<p id="isPasted">As electronic devices continue to evolve and proliferate, at once making our day-to-day lives easier and enhancing capabilities on an industrial level, the question of environmental impact becomes increasingly urgent. That’s because just as electronic devices and products become more ubiquitous, so too does electronic waste. In 2022 alone, a reported 62 million tonnes of e-waste was produced, marking a massive 82% jump from 2010.<sup>[1]</sup> If that wasn’t concerning enough, this volume of e-waste is rising at a rate of five times faster than documented e-waste recycling.</p><p>While these are daunting figures, there are real efforts being made to minimize e-waste and the general ecological footprint of electronic devices as well as to facilitate recycling of components like printed circuit boards (PCBs). This will be the focus of this article and an upcoming <a href="https://www.eventbrite.ca/e/printing-biodegradable-pcbs-tickets-1361028917129?aff=wevolver">webinar</a> hosted by Voltera with guest Jiva Materials on June 5, 2025.</p><p><span class="fr-img-caption fr-fic fr-dib fr-draggable"><span class="fr-img-wrap"><a href="https://www.eventbrite.ca/e/printing-biodegradable-pcbs-tickets-1361028917129%E2%80%9D%20with%20%E2%80%9Chttps://www.eventbrite.ca/e/printing-biodegradable-pcbs-tickets-1361028917129?aff=wevolver" target="_blank" rel="noopener noreferrer"><img src="https://images.wevolver.com/eyJidWNrZXQiOiJ3ZXZvbHZlci1wcm9qZWN0LWltYWdlcyIsImtleSI6ImZyb2FsYS8xNzQ3OTg2ODIzNDQ0LVdlYmluYXIgMTFfRXZlbnRicml0ZSBoZWFkZXIuanBnIiwiZWRpdHMiOnsicmVzaXplIjp7IndpZHRoIjo5NTAsImZpdCI6ImNvdmVyIn19fQ==" style="width:100%px" class="fr-fic fr-dib" /><span class="fr-inner">Find more details about the upcoming webinar, including how to register </span></a><a href="https://www.eventbrite.ca/e/printing-biodegradable-pcbs-tickets-1361028917129%E2%80%9D%20with%20%E2%80%9Chttps://www.eventbrite.ca/e/printing-biodegradable-pcbs-tickets-1361028917129?aff=wevolver" id="isPasted">here</a></span></span></p><h2 id="isPasted">The environmental cost of traditional PCBs</h2><p>The environmental impact of the electronics industry has been a significant concern in recent years, as the market for electronic products, including smart devices and IoT appliances, has continued to grow. This ecological impact is both generated by e-waste—one of the fastest growing solid waste streams in the world according to the WHO <sup>[2]</sup>—as well as through the manufacturing of electronic components, including printed circuit boards. </p><p>PCB production specifically has been flagged as an environmental issue for a few reasons. For one, many of the materials currently used in PCBs are non-renewable, including conductive metals like copper, rare earth elements (REE) like neodymium, and epoxy resins. Looking at the life cycle of a PCB, the extraction and mining process for copper ore and REE can’t be ignored: not only are these energy intensive, they result in the pollution of land and water. Moreover, the mass manufacturing of PCBs is also energy intensive, requiring high-temperatures for processes like lamination and the use of industrial equipment that generates harmful emissions.</p><p><span class="fr-img-caption fr-fic fr-dib"><span class="fr-img-wrap"><img src="https://images.wevolver.com/eyJidWNrZXQiOiJ3ZXZvbHZlci1wcm9qZWN0LWltYWdlcyIsImtleSI6ImZyb2FsYS8xNzQ3OTg2ODM5ODM4LVJGSUQgcHJpbnQuanBnIiwiZWRpdHMiOnsicmVzaXplIjp7IndpZHRoIjo5NTAsImZpdCI6ImNvdmVyIn19fQ==" style="width:100%px" class="fr-fic fr-dib" /><span class="fr-inner">An RFID tag printed on Voltera’s NOVA platform with Copprint LF-301 nanocopper ink on paper</span></span></span></p><p id="isPasted">Perhaps the greatest ecological challenge, however, has come from the disposal and recycling of PCBs. Since the components that make up a PCB—including resin, glass and conductive pathways—are bonded, it is difficult to separate them at the end of the PCB’s life. This has meant that the vast majority of defective or outdated PCBs end up in landfills, making up 42% of e-waste by weight.<sup>[3]</sup> On top of that, up until very recently, the most viable PCB recycling processes relied on incineration, which not only consumes energy itself, but also generates toxic emissions. </p><h2>Introducing Soluboard®</h2><p>Fortunately, there have been recent advances in making PCBs more sustainable. One of these advances comes from UK-based Jiva Materials, which has developed the world’s first fully recyclable PCB substrate, Soluboard®.</p><p>Soluboard® is a game-changer in rigid PCB production, offering a carbon footprint reduction of up to 67% compared to more conventional glass-fiber and epoxy substrates. The eco-friendly substrate is made by impregnating natural, degradable fibers within a water-soluble polymer along with a halogen-free flame retardant. This results in a composite material that is formed into copper clad laminate panels, which form the base of PCBs.</p><p>The Soluboard® substrate can be used in PCB production workflows, using techniques like water-based etching, electroplating or printing technologies like Voltera’s <a href="https://www.voltera.io/blog/introduction-direct-ink-writing-printing-technology?utm_campaign=Wevolver&amp;utm_source=website&amp;utm_medium=soluboard&amp;utm_content=diw">direct-ink-writing</a> (DIW), as well as curing, drilling, and more. At the end of the PCB’s life, the board can simply be placed in hot water (within a controlled environment), where the substrate will dissolve, making it easier to recover reusable materials, like copper, rare minerals, and the natural fiber. These materials can then be reused in the production of new PCBs.</p><h3>The Benefits of Soluboard®:</h3><ul><li><p>Made from biodegradable non-toxic materials </p></li><li><p>Facilitates recovery of non-renewable materials, like copper and rare minerals</p></li><li><p>Compatible with standard processes like water-based etching, electroplating, drilling, routing, and soldering (including low temperature soldering)</p></li><li><p>Compatible with Plated Through Hole (PTH) </p></li><li><p>Demonstrates flame retardancy rating equivalent to UL94 V1</p></li><li><p>Reduces carbon footprint by 67% compared to FR4 substrates</p></li></ul><h2>Voltera’s contribution to sustainable printed electronics</h2><p>Other solutions, like Voltera’s aforementioned DIW printing systems, are also playing a key role in the development of more sustainable PCBs. The company’s flagship novel electronics printing platform, <a href="https://www.voltera.io/products/nova?utm_campaign=Wevolver&amp;utm_source=website&amp;utm_medium=soluboard&amp;utm_content=nova">NOVA</a>, uses a precision dispensing system to selectively deposit conductive or dielectric inks onto a wide variety of substrates. This solution not only enables users to rapidly iterate electronic devices—such as sensors and wearables—to accelerate development, but also supports materials research and serves as a key tool in the development of more sustainable PCB materials and devices.</p><p>For example, NOVA is a great tool for testing the compatibility between sustainable substrates—such as the rigid Soluboard® or flexible substrates like paper and PET—and printable materials, including those at the cutting-edge of sustainable electronics, like carbon and graphene-based formulations. Researchers can therefore use Voltera’s technology to explore how these materials perform together and to develop new applications that support more sustainable electronics. </p><p>A number of <a href="https://www.voltera.io/use-cases/customer-stories" target="_blank" rel="noopener noreferrer">Voltera customers</a> are currently investigating the use of self-healing materials to make electronics that can heal themselves when a defect occurs. For instance, a research team at Polytechnique Montreal is using the Voltera’s products to develop self-healing, stretchable and recyclable polyurethane-PEDOT:PSS materials, which could have applications in biosensing and pressure sensing.<sup>[4]</sup> The Bao Group at Stanford is also working with the <a href="https://www.voltera.io/products/v-one?utm_campaign=Wevolver&amp;utm_source=website&amp;utm_medium=soluboard&amp;utm_content=v-one">V-One PCB printer</a> to develop self-healing robotic skins.<sup>[5]</sup> The sustainable impact of this capability could be massive down the line, as PCBs and sensors could have longer lifespans, directly minimizing e-waste.</p><p><span class="fr-img-caption fr-fic fr-dib"><span class="fr-img-wrap"><img src="https://images.wevolver.com/eyJidWNrZXQiOiJ3ZXZvbHZlci1wcm9qZWN0LWltYWdlcyIsImtleSI6ImZyb2FsYS8xNzQ3OTg2OTgyMTY2LWV6Z2lmLTM2ZWY4MDM1NDlmMTBmLmpwZyIsImVkaXRzIjp7InJlc2l6ZSI6eyJ3aWR0aCI6OTUwLCJmaXQiOiJjb3ZlciJ9fX0=" style="width:100%px" class="fr-fic fr-dib" /><span class="fr-inner">Students from Politechnique Monstreal using NOVA for materials research</span></span></span></p><p id="isPasted">Voltera’s NOVA and V-One platforms offer additional sustainability benefits, including minimized material usage and waste resulting from the additive deposition approach. Since this method deposits material only where needed, there is far less waste than more conventional processes like etching, which is subtractive. </p><p>The desktop printing solutions also allow R&amp;D labs and electronic developers to bring their prototyping in-house, eliminating reliance on third-party manufacturing and the emissions associated with shipping. On top of that, by directly printing electronic circuits based on digital designs, Voltera’s solutions eliminate the need for PCB screens and other tooling, further lowering the environmental impact. </p><h2>Learn more about sustainable electronics </h2><p>The state of sustainable PCBs will be the focus of an upcoming webinar hosted by Voltera with guest Jiva Materials. The online event, taking place on Thursday June 5, 2025 at 11 a.m ET, will present technological innovations that are pushing electronics in a more ecological direction. </p><p>Jack Herring, CPO and Founder of Jiva Materials will present the innovative Soluboard®, explaining in detail its technical specifications and applications in PCB production.

On the road to more sustainable printed electronics

<p id="isPasted">Multilayer printed circuit boards (PCBs) represent a growing proportion of PCBs made today, with the growth driven in large part by the increased demand for miniaturized electronics. It makes perfect sense: after all, smaller electronic devices necessitate the compaction of circuits without decreasing functionality. In this article, we’ll be looking more specifically at testing and repair techniques for multilayer PCBs and the challenges that this type of circuit brings up. We’ll also be talking about technologies at the forefront of PCB repair, including XTPL’s direct writing platform.</p><h2>Understanding Multilayer PCBs</h2><p>Before diving into repair methods for multilayer PCBs, it is first important to understand the role of this type of circuit in the broader electronics industry. Generally speaking, there are different types of printed circuit boards, including single-sided PCBs, double-layer PCBs, and multilayer PCBs. The latter are the most complex and typically have the greatest functionality. In the simplest terms, this is because combining multiple layers into a single PCB makes it possible to increase the amount of circuitry without significantly increasing the board’s footprint. </p><p>While any PCB with at least three layers is considered a multilayer PCB, it is technically possible to have hundreds of layers in a single PCB. In a smartphone, most PCBs have around 10 layers.<sup>[1]</sup> Unlike single-layer PCBs, which consist of a conductive layer on a substrate, multilayer PCBs sandwich conductive layers (typically copper foils) and insulating layers (prepregs and core) above and below a rigid substrate. </p><p>There are several benefits to integrating multilayer PCBs in electronic devices, including greater circuit density, which allows for greater functionality and performance while economizing on size. Multilayer PCBs also tend to be higher in quality since they require more in-depth planning at the design stage than simpler PCBs. </p><p>Despite these benefits, however, multilayer PCBs do bring with them an added level of complexity, not only in terms of production methods but also when it comes to repair. This complexity is driven by a couple of factors. For one, identifying where a fault exists in the multilayer PCB is far more challenging than with a single-sided PCB, since a defect can be located on one of the board’s inner layers. When the fault is found, it then requires extreme precision to repair it without damaging or compromising the rest of the board. Unfortunately, these challenges have often meant that whenever a multilayer PCB isn’t functioning properly, it has to be completely replaced. </p><h2>Diagnostic Techniques for Multilayer PCBs </h2><p>Fortunately, advanced technologies and manufacturing methods are unlocking more effective diagnosing and repair of defective multilayer PCBs. Let’s take a look at some of the techniques that are making a difference.</p><p>In order to identify a defect in a multilayer PCB, electronics manufacturers and repair shops can use a variety of diagnostic tools, such as a multimeter, which can measure the current of the PCB at different points to find an open circuit. In-circuit testing (ICT) is another commonly used method, which positions probes at specific points of the PCB to measure resistance and other factors. Both of these quality control tests are non-destructive and can thus be helpful for finding a defective circuit, but may be limited when it comes to finding the exact location of a broken or weak trace.</p><p>For this, there are more advanced non-destructive processes, like X-ray scanning or automated optical inspection (AOI). X-ray technology can capture images of the internal structure of a multilayer PCB and reveal specific defects. AOI, for its part, uses specialized high-res cameras and advanced software to scan multilayer circuits, comparing the final product to the original Gerber file to identify any discrepancies. With AOI, it is key that the layers of a multi-layer PCB are scanned before final assembly and lamination.</p><h2>Repairing Multilayer PCBs</h2><p>Unfortunately, the repair of multilayer printed circuit boards remains a big challenge in the electronics industry. It’s easy to understand why: if there is any defect or damage to one of the inner laminated layers of a PCB, it is very difficult (and in some cases impossible) to get inside to repair it without damaging or compromising another element of the board.</p><p>There are techniques like microdilling that can give repair professionals access to a defective trace inside a multilayer PCB. In most cases where this is possible, a defective trace or via would have to be rerouted using a conductive trace or wire. Generally, delaminating a multilayer PCB is not recommended since it is both time and cost consuming.</p><p>There are also other PCB board repair techniques that can be implemented for multilayer PCBs, particularly when a defect is located on the board’s surface. For example, direct writing processes like XTPL’s Ultra-Precise Dispensing (UPD) technology can <a href="https://xtpl.com/pcb-boards-how-to-repair-open-defects-with-xtpl/">repair open defects in PCBs</a> with a high degree of efficiency and precision. More specifically, UPD uses a pressure-based dispenser to selectively deposit conductive nanoinks or nanopastes onto a substrate. Notably, the technology is capable of dispensing traces and lines with a resolution of 1 µm, making it suitable for miniaturized electronic circuits. </p><p>When it comes to PCB repair, XTPL’s UPD technology can fill in broken or too-thin traces with a conductive ink, like Ag Nanoink CL34, a conductive silver ink with up to 50% bulk silver conductivity. The company’s silver Nanopaste CL85, one of its flagship products, offers a higher viscosity that makes it possible to apply the material to vertical surfaces and 3D topographies with a high level of accuracy. </p><h2>XTPL, at the Forefront of PCB Repair</h2><p>Ultimately, dispensing processes like XTPL’s UPD are suitable for circuit board testing and repair, particularly when it comes to single-sided and double-layer PCBs. But they can also be employed to repair the surfaces of multilayer PCBs or inner circuits before they are laminated, helping electronics manufacturers to overcome some of the challenges of repairing multilayer PCBs.</p><hr /><h2 id="isPasted">Resources</h2><p>[1] PCB Design Requirement for Smartphones [Internet].

Multilayer PCBs are at the forefront of printed electronics today but bring with them some challenges related to testing and repair.

Multilayer PCBs and the Cutting-Edge of Circuit Board Repair

<p id="isPasted">Reliability is a top priority in defense and aerospace electronics in harsh, unforgiving environments. The MIL-I-46058C standard is a guideline for <a href="https://hzo.com/conformal-coating-types" rel="noopener" target="_blank">conformal coating materials</a> that helps keep PCBAs safe from military environments, ensuring dependable performance. Although<a href="https://www.ipc.org/TOC/IPC-CC-830C-toc.pdf" rel="noopener" target="_blank"> IPC-CC-830</a> replaced this standard in 1998, understanding MIL-I-46058C is still non-negotiable for industry compliance and mission success.</p><p>Even though deemed inactive for new designs since 1998, MIL-I-46058C remains an independent standard for companies who supply conformal coatings for two essential reasons: it is the only published standard that includes a qualified product list used by the DOD, and the standard also requires certification by an independent third party.</p><p>The criteria set forth by MIL-I-46058C for conformal coatings are integral in <a href="https://hzo.com/blog/conformal-coating-for-drones-which-is-best" rel="noopener" target="_blank">aerospace</a> and defense applications. These coatings must withstand extreme atmospheric conditions, rapid pressure changes, and varying degrees of moisture and chemical exposure. Adherence to such standards ensures operational effectiveness and safety in critical missions.</p><h2>Importance of MIL-I-46058C</h2><p>In the realm of military specifications and standards, MIL-I-46058C stands out for its stringent criteria for conformal coatings. It represents a level of assurance for military equipment that non-military standards do not necessarily guarantee. By complying with this specification, manufacturers and defense contractors can affirm the longevity and performance of their electronic components, even in the harshest environments, by using the proper coating materials.</p><p>The primary function of conformal coatings is protection: they are a <a href="https://hzo.com/solutions/protection-capabilities" rel="noopener" target="_blank">barrier that prevents contamination</a>, such as chemicals, moisture, and humidity, from causing short circuits or <a href="https://hzo.com/blog/corrosion-water-damage-electronics" rel="noopener" target="_blank">corrosion</a>.</p><p>Coatings such as acrylics, <a href="https://hzo.com/blog/polyurethane-conformal-coating-services-for-electronics" rel="noopener" target="_blank">urethanes</a>, <a href="https://hzo.com/blog/epoxy-conformal-coating-services-for-electronics" rel="noopener" target="_blank">epoxies</a>, silicones, and <a href="https://hzo.com/coatings/parylene-coating" rel="noopener" target="_blank">Parylene </a>also resist corrosive gases and salt sprays, reduce mechanical stress due to handling or thermal expansion, and protect against corrosive gases and salt sprays.</p><p>MIL-I-46058C is pivotal in enhancing product longevity and dependability by defining the performance criteria for conformal coatings. Electronics treated with MIL-spec conformal coatings typically showcase better performance over their lifecycle and are less likely to fail due to electrical shorts, interference, or damage from environmental factors.</p><p>Examples of criteria include:</p><ul><li><a href="https://hzo.com/blog/what-is-dielectric-strength-formula-testing-table-of-values" rel="noopener" target="_blank">Dielectric Breakdown Resistance</a>: Coatings must not degrade when subjected to high voltages.</li><li>Insulation Resistance: Coatings should maintain high resistance to prevent leakage currents.</li><li>Hydrolytic Stability: Insulation properties must remain intact even when exposed to moisture.</li><li><a href="https://hzo.com/blog/what-is-thermal-conductivity-explanation-measurement-uses" rel="noopener" target="_blank">Thermal Shock Resistance</a>: The insulating capacity must withstand sudden temperature changes.</li></ul><h2>Military Standards for Humidity and Environmental Protection</h2><p>MIL-I-46058C establishes clear humidity and environmental protection requirements.

This characteristic is particularly valuable in high-density circuitry where electrical components are closely packed, reducing the risk of interference or shorts between conductors.</p><p>Coatings under the MIL-I-46058C specification are designed to act as electrical insulators, creating a dielectric layer that safeguards circuitry from shorts and arcing caused by environmental challenges.</p><p>Their resistance to electricity contributes significantly to preventing malfunctions and potential damage. With an appropriate application, conformal coatings provide excellent insulation, even under fluctuating electrical loads.</p><h3>Defining Thermal and Mechanical Standards</h3><p>The MIL-i-46058C specification is instrumental in defining the thermal and mechanical performance parameters for conformal coatings used in military and aerospace applications. It ensures that coatings are capable of functioning under stringent conditions without degrading performance, encompassing:</p><ul><li><a href="https://hzo.com/blog/tensile-strength-at-yield-testing-standards-specs-material" rel="noopener" target="_blank">Tensile Strength</a>: The coating's ability to withstand pulling forces without breaking</li><li>Thermal Shock Resistance: The coating's capacity to endure sudden changes in temperature without compromising its structural integrity</li><li>Flexibility: The ability of the coating to flex with the substrate material, which is essential for performance during mechanical or thermal stress</li></ul><h2>Mastering Application Techniques for MIL-I-46058C Conformal Coatings</h2><p>Whichever application process (dipping, spraying, <a href="https://hzo.com/coatings/parylene-coating/process" rel="noopener" target="_blank">vacuum deposition</a>, brushing) is used, achieving uniform coating and coverage is the primary concern. Factors such as temperature, humidity, and the geometry of the printed circuit board (PCB) can all influence the outcome. It's essential to follow strict processing guidelines, provide adequate training for operators, and implement inspection procedures to ensure that the conformal coatings delivered meet the high standards set by MIL-I-46058C.</p><h3>Quality Control, Testing, and Industry Compliance</h3><p>In the realm of conformal coatings and electronic circuit protection, Quality Control (QC) and rigorous testing are pivotal in ensuring that products meet the stringent requirements of MIL-I-46058C. For manufacturers and service providers in the electronics industry, adherence to recognized standards is a benchmark for quality and a requirement for credibility and trustworthiness in the marketplace.</p><p>It's essential to have a well-established process encompassing multiple tests and inspections to comply with the MIL-I-46058C specification. This involves:</p><ul><li>Thorough examination of thickness uniformity and coverage using various measurement techniques</li><li>Stringent electrical testing to ensure that the conformal coating does not impede the intended function of the PCB</li><li>Mechanical and environmental stress testing to verify that the coating can withstand harsh conditions without degrading</li></ul><p>Quality control in the application of conformal coatings is multi-faceted, including:</p><ul><li>Visual inspections for <a href="https://hzo.com/blog/common-conformal-coating-defects-and-solutions" rel="noopener" target="_blank">surface defects</a> post-application</li><li>Adherence to production protocols that minimize the risk of contamination</li><li>Product batch testing to ensure consistent quality across different manufacturing lots</li></ul><p>These QC procedures are integral to maintaining the high standards expected in industries where reliability is paramount.</p><h2>Processes for Ensuring Compliance with MIL-I-46058C</h2><p>Coatings optimized for the MIL-I-46058C specification must undergo tests to affirm that the PCBs meet the rigorous demands of their respective applications. The MIL-I-46058C specification outlines a series of stringent tests to evaluate the corrosion resistance of conformal coatings.</p><p>High humidity exposure, salt fog conditions, and immersion trials are methods used to simulate extreme environments and validate a coating's protective capabilities. Adherence to these testing protocols is crucial for manufacturers to certify that their conformal coatings meet the high standards expected for components in critical applications.</p><ul><li>Humidity Exposure: Coatings are tested for their ability to withstand high moisture levels without degrading.</li><li>Salt Fog/Spray Testing: Assesses the coating's resistance to corrosive salt environments mimicking marine conditions.</li><li>Immersion Trials: Ensures that coatings can protect components even when submerged in liquids.</li></ul><p>Through rigorous testing and compliance with MIL-I-46058C, electronics manufacturers can ensure that their products stand up against environmental challenges, thereby reducing maintenance costs and extending the operational lifespan of the devices they protect.</p><p><span class="fr-video fr-deletable fr-fvc fr-dvb fr-draggable"><iframe width="640" height="360" src="https://www.youtube.com/embed/X5bOkx2wC6s?&amp;wmode=opaque&amp;rel=0&amp;enablejsapi=1&amp;origin=https://www.wevolver.com" frameborder="0" class="fr-draggable"></iframe></span></p><h2 id="isPasted">Industry Certifications and Compliance</h2><p>While the MIL-I-46058C provides a comprehensive framework, aligning with broader industry certifications reinforces a commitment to excellence.

<p id="isPasted"><a href="https://hzo.com/conformal-coating-types" rel="noopener" target="_blank">Conformal coatings</a> are polymeric films on printed circuit boards (PCBs) that protect against hazards like moisture, pollution, chemicals, and temperature changes. This layer of material is vital for the longevity and reliability of electronic parts. But sometimes, conformal coating removal or rework is necessary.</p><p>There are five primary conformal coating materials: acrylics, epoxies, silicones, urethanes, and Parylene. Each material presents its advantages, limitations, challenges, and application methods. Understanding these details can help operators determine how best to remove each material. This is why we will start with a brief summary of each coating material's properties.</p><h3><strong>Acrylic (AR) Conformal Coating Properties</strong></h3><ul><li>Low moisture absorption</li><li>Relatively short drying times</li><li>Clear protective coating</li><li>Good electrical and physical properties</li><li>Typically brushed, sprayed, or dipped</li></ul><h3><strong>Epoxy (ER) Conformal Coating Properties</strong></h3><ul><li>Very robust</li><li>Excellent chemical and abrasion resistance</li><li>Very rigid conformal coating</li><li>High dielectric strength</li><li>Typically brushed, sprayed, or dipped</li></ul><h3><strong>Silicone (SR) Conformal Coating Properties</strong></h3><ul><li>Good humidity and moisture resistance</li><li>Low toxicity</li><li>Easy to apply</li><li>Easy to repair</li><li>Typically brushed, sprayed, or dipped</li></ul><h3><strong>Properties of Urethane (UR) Conformal Coatings</strong><strong> </strong></h3><ul><li>Moisture and oil-resistant</li><li>Fungicidal</li><li>Good flexibility</li><li>Can be thinned to achieve a chosen viscosity</li><li>Typically brushed, sprayed or dipped</li></ul><h3><strong>Properties of Parylene (XY) Conformal Coatings</strong></h3><ul><li>Biostable, biocompatible</li><li>Excellent chemical resistance</li><li>Superior conformality</li><li>Exceptional corrosion resistance</li><li>Applied by chemical vapor deposition (CVD)</li></ul><p><img src="https://s3-us-west-1.amazonaws.com/wevolver-project-images/froala%2F1744699992332-BL0100_HZO_Conformal_Coating_Removal_Inline_1.webp" style="width:100%px" class="fr-fic fr-dib" /></p><h2 id="isPasted">Why Does Conformal Coating Need to be Removed?</h2><ul><li>Incorrect application - this may lead to incomplete coverage, bubbles, or excessive thickness. If these defects hurt the circuit board's function or reliability, operators must remove and reapply the coating.</li><li>Need for repairs - during repairs, removal allows for precise soldering and component replacement.</li><li>Rework - this often involves altering circuits, necessitating access that is obstructed by existing coatings.</li><li>Failure analysis - failure analysis can prevent future errors. But, technicians must examine the original circuit materials without obstruction.</li></ul><h2>Before Removing Conformal Coatings - Safety Precautions</h2><p>Safety is paramount before removing conformal coatings from electronic components. The compounds and methods for stripping conformal coatings can be risky. If proper precautions are not followed, they can harm health.</p><h3>Essential Safety Measures</h3><p>Dedicated working environments with adequate ventilation are required. This is non-negotiable. Solvent fumes can be harmful if inhaled in high concentrations. So, a well-ventilated area, using natural means or fume extractors, minimizes inhalation risks. Also, some coating removal techniques create dust or aerosols. So, use suitable air filtration systems.</p><p>Flammability is another factor to consider. Several solvents and chemicals employed in the removal processes are highly flammable. To prevent combustion, keep the workspace free of ignition sources, like sparks or open flames.</p><p>Electricity poses a significant risk. Turn off and unplug all devices. This will prevent accidents during the conformal coating removal process.</p><h2>How to Remove Conformal Coating - First Step</h2><p>Check the coating on the PCB you want to remove. This will help find the best method to remove the conformal coating. You can usually confirm this by contacting your coating supplier. Or, look for a JEDEC or IPC label on the board. Coatings are designated as AR, SR, ER, UR, or XY, indicating which coating you are working with. If there are no labels, you can still identify the material via methods outlined by the IPC below.<br />Each conformal coating has distinct properties. So, you can test for transparency, solubility, hardness, thermal removal, and thickness. These tests will show you which type of coating you have. For more information, see <a href="https://www.ipc.org/TOC/IPC-HDBK-830.pdf" rel="noopener" target="_blank">IPC’s “Coating Removal, Identification of Conformal Coating” guidelines</a>.</p><h2>Coating Removal Techniques</h2><p>After identifying your coating, the next step is to choose the removal technique. Popular methods are briefly discussed below:</p><h3><strong>Peeling Method</strong></h3><p>For RTV silicone or thick rubber coatings, use a dull blade or knife to slit and peel off the coating.</p><h3><strong>Chemical Solvent Method</strong></h3><p>This process effectively removes urethane, acrylic, and silicone coatings. Prep the area with high-temperature tape and apply solvent using a foam swab.</p><h3><strong>Grinding and Scraping Method</strong></h3><p>This removal technique can grind away thin, hard coatings with a micro motor or rotary-style tool or soft coatings with a rotary brush.</p><h3><strong>Thermal Method</strong></h3><p>Using low-temperature heat, gently burn and melt the coating material.</p><h3><strong>Micro Sandblaster Method</strong></h3><p>This technique involves projecting a fine abrasive powder onto the coating to flake off the material.</p><p><img src="https://s3-us-west-1.amazonaws.com/wevolver-project-images/froala%2F1744700313082-BL0100_HZO_Conformal_Coating_Removal_Inline_2.webp" style="width:100%px" class="fr-fic fr-dib" /></p><h2 id="isPasted">Which Technique is Best for My Conformal Coating Material?</h2><h3><strong>Urethane Coatings</strong></h3><ul><li>Grinding and scraping method</li><li>Solvent method</li><li>Micro-blasting method</li></ul><h3><strong>Acrylic Coatings</strong></h3><ul><li>Thermal removal method</li><li>Chemical solvent method</li><li>Scraping and grinding method</li><li>Micro-blasting method</li></ul><h3><strong>Epoxy Coatings</strong></h3><ul><li>Thermal removal method</li><li>Grinding and scraping method</li><li>Micro-blasting method</li></ul><h3><strong>Silicone Coatings</strong></h3><ul><li>Grinding and scraping method</li><li>Micro-blasting method</li><li>Chemical solvent method</li><li>Thermal method</li></ul><h3><strong>Parylene Coatings</strong></h3><p>Parylene coatings are often hard to remove. You can usually use micro-blasting, grinding, scraping, and thermal methods. But at HZO, we have simplified the reworking process using technology.

Conformal Coating Removal - How to Get Started WReference

<p id="isPasted">If you're reading this article on ensuring good Parylene adhesion, chances are you already know a bit about<a href="https://hzo.com/coatings/parylene-coating" rel="noopener" target="_blank"> Parylene</a> and its <a href="https://hzo.com/coatings/parylene-coating/properties/" rel="noopener" target="_blank">properties</a>, and now you're more curious about the process. As the Process Engineer Manager at HZO, I can't stress enough how beneficial streamlined, optimized production processes are when bringing our customer concepts to life. </p><p>Our customers come from different industries but tend to want one thing in common—a durable, high-performance coating. <a href="https://hzo.com/blog/why-is-parylene-coating-conformal-process-makes-perfect" rel="noopener" target="_blank">Parylene</a> needs <em>good adhesion to do that</em>. <br /><br />You already understand the importance of a clean, well-prepared surface from daily life. When was the last time you waxed your car without washing it first? If you applied wax over a dirty, dusty, or greasy surface, the wax wouldn't bond adequately; there would be streaks, uneven coverage, and poor protection. <br /><br />Similarly, if a PCBA isn't adequately cleaned before applying a <a href="https://hzo.com/blog/parylene-c-biocompatibility-properties" rel="noopener" target="_blank">Parylene coating</a>, contaminants prevent it from adhering well, leading to weak coverage and potential failure. Surface preparation is understood and used across various industries—from chefs thoroughly cleaning a non-stick pan of debris before cooking to nail salons, filing and buffing nails, and swabbing them with acetone before applying paint. <br /><br />Yet, it is a concept that I feel isn't discussed enough when we talk about coating reliability. I'm going to explain why surface prep and cleaning might be more important than you think and give you an overview of the process so you can walk away with some actionable tips to use on your production line. I will go into precise cleaning techniques, so if you are an assembler and your goal is to clean your PCBAs and components before sending them to be coated, you will also find value in this post.<br /><br />But first, let's talk about why your assemblies and components need surface prep. </p><h2>Careful! That Sample May Not Be As Clean As You Think </h2><p>Surface preparation and board cleaning are hot topics in our industry, and an entire history of why this is a debate would be beyond the scope of this article. If you are looking for that type of deep dive, <a href="https://www.aqueoustech.com/learning-center" rel="noopener" target="_blank">Aqueous has a great reference</a>.<br /><br />I've observed, anecdotally, in my career that prospective customers often choose to skip surface preparation during sampling, and this can correlate with poor coating adhesion. Despite explaining the importance of surface preparation for achieving strong adhesion, we've encountered situations where, when we first recommend cleaning and outline the risks of not doing so—such as encapsulating contaminants like dust or dirt—prospects often decline to proceed with cleaning in order to save on costs or processing time. <br /><br />While there are cases where the outcome is acceptable, failures frequently occur due to contaminants trapped on the board. Given that not all potential sources of contamination on the manufacturing floor are immediately visible to the naked eye, our partners may be misled into skipping this crucial step. This can lead to issues down the line, as even invisible contaminants can compromise the quality of the coating adhesion and ultimately can lead to corrosion and other reliability issues.<br /><br />This can frustrate our partners because of wasted time and resources, as we will have to start again, this time with surface preparation. However, it's somewhat understandable if you don't consider all of the possible sources of contamination on the manufacturing floor that may not even be visible to the human eye. </p><p>Contamination Sources </p><ul><li>Flux residues</li><li>Material handling </li><li>Upstream/ Downstream </li><li>Touch up and Repair </li><li>Fingerprints</li><li>Dirt </li><li>Lint</li><li>Skin oils </li><li>Hand Lotions</li><li>Salts from worker perspiration </li><li>Particulate matter in the air from cardboard </li></ul><p><img src="https://s3-us-west-1.amazonaws.com/wevolver-project-images/froala%2F1744246639467-hzo-surface-cleaning-contaminents.webp" style="width:100%px" class="fr-fic fr-dib" /></p><p id="isPasted">Think of these tiny contaminants as ticking time bombs when they come between the Parylene coating and your component. The coating may not lift right away - causing delamination - but only time will tell if you have a huge issue on your hands. If you're not a fan of risk, read about how to ensure good <a href="https://hzo.com/blog/parylene-coating-thickness-how-much-is-enough" rel="noopener" target="_blank">Parylene</a> adhesion with surface prep and precise cleaning techniques.</p><h2><br />Ensuring Adhesion with The Surface Prep Process</h2><p>Again, proper preparation of the substrate is crucial for the coating to adhere correctly. The surface should be clean (as possible) and free of contaminants that could interfere with the bonding process. First, use appropriate cleaning agents for the substrate to remove grease, dirt, oil, and other contaminants. <br /><br />The choice of cleaning agent depends on the type of contamination and the material of the substrate. Common cleaning agents include:<br /><br />Solvent and Aqueous-Based Cleaners</p><ul><li>Isopropyl Alcohol (IPA): Effective for removing light oils, grease, and flux residues.</li><li>Alkaline Detergents: Solutions containing surfactants, such as sodium hydroxide or potassium hydroxide, break down organic contaminants.</li><li>Citrus-Based Cleaners: Environmentally friendly options that dissolve oils and grease.</li><li>Deionized (DI) Water with Detergents: Used for water-soluble contaminants and light residues.</li></ul><p>At HZO, we commonly recommend an ultrasonic wash and bake for precision removal and less abrasive cleaning. The ultrasonic wash uses high-frequency sound waves in a cleaning solution to remove contaminants such as dust, oils, and residues from the substrate at a microscopic level.</p><p>This method provides deep, uniform cleaning, especially for intricate or delicate components. Following this, the bake step involves heating the substrate to eliminate moisture and volatile residues that could interfere with the adhesion and uniformity of the parylene coating. Together, these steps enhance coating reliability, ensuring a clean and stable surface for deposition.<br /><br />Specific pre-treatment surface modification steps may be required depending on the material, such as aluminum, steel, or plastic. You can use physical surface modification to give the Parylene physical roughness to latch onto. At HZO, we use plasma to roughen the surface and increase the surface area for adhesion. In this process, bombardment by active Argon atoms causes roughening at the molecular level.<br /><br />You can also use chemical surface modification methods. These give coatings like <a href="https://hzo.com/blog/how-much-does-parylene-coating-cost-all-things-considered" rel="noopener" target="_blank">Parylene</a> a chemically attractive surface on which to bond. We use adhesion promotors such as silane to create a stronger bond. </p><h3>Precise Cleaning Techniques  </h3><p>Cleaning is not just about removing visible dirt; it also involves eliminating microscopic contaminants that could prevent the coating from bonding or make customer parts appear aesthetically unappealing. We tailor the cleaning method to the contamination and the substrate. Sensitive substrates cannot handle all cleaning methods. <br /><br />For example, isopropyl alcohol is sometimes used to clean surfaces. We avoid solvent cleaning unless we know it's the proper solvent for the material to prevent damage or ensure no residues that could affect adhesion. After using solvents, we recommend using dry, filtered air to blow off any remaining residues or moisture. <br /><br />The following chart describes types of substrate materials and their reactions to cleaning methods. </p><table><tbody><tr><td><strong>Substrate Materials</strong></td><td>Reactions to Cleaning Methods</td></tr><tr><td>Electronic Components</td><td>Generally tolerate all cleaning methods, but items such as displays, MEMS, and optical components can be sensitive.</td></tr><tr><td> Solder Mask</td><td>Very robust but can be discolored by plasma. A known point of delamination and contamination in surface energy.</td></tr><tr><td>Other Conformal Coatings</td><td>Some conformal coatings have very low surface energy, and some can inhibit cure of other coatings (acrylics and silicones, for instance).</td></tr><tr><td>Solder Joints</td><td>Combined with the standoff gap of components and chips, these are areas most likely to hold contaminants both before cleaning (flux) and after (the solvent or detergent).</td></tr><tr><td>Other Metallic Surfaces</td><td>Copper and silver can be discolored by aqueous/acidic/basic solutions in cleaning, as well as possible oxidation or tarnishing.</td></tr></tbody></table><h3>Compressed Air and Ionizers </h3><p>Compressed air and air ionizers play a crucial role in the final stages of surface preparation for Parylene coating by ensuring no residual contaminants remain on the substrate. Dry, filtered compressed air, used in short bursts to avoid dislodging components, can remove any remaining dust, lint, or microscopic debris that may have settled after previous cleaning steps. This step is crucial for intricate or delicate components where trapped particles could compromise coating uniformity. <br /><br />Alongside compressed air, air ionizers are often used to help neutralize static charges that attract dust and contaminants to the surface, especially in environments with sensitive electronics or plastic components. By eliminating electrostatic forces, air ionizers prevent airborne particles from re-adhering, ensuring a clean, contamination-free surface for optimal Parylene adhesion and performance.</p><h2>Environmental Considerations and Safe Handling Procedures</h2><p>Environmental conditions, such as room cleanliness, can affect the quality of a coating application. Specks of dirt, lint, or other particulates in the air could easily land on the components or assemblies. Keep items such as cardboard boxes off the floor and the production line orderly. <br /><br />The process is always essential. To avoid contamination before coating, ensure that the coated parts are not exposed to contaminants like dust, as contaminants on the surface may interfere with adhesion.<br /><br />Additionally, industry standards, such as <a href="https://shop.ipc.org/ipc-a-610" rel="noopener" target="_blank">IPC-A-610</a>, provide recommended practices for safely handling electronic assemblies to minimize the amount of contamination. Recommendations include: </p><ol><li>Keep workstations clean and neat. Do not eat, drink, or use tobacco products in the work area. </li><li>Minimize the handling of electronic assemblies and components to prevent damage. </li><li>When gloves are used, change as frequently as necessary to prevent contamination from dirty gloves. </li><li>Do not handle solderable surfaces with bare hands or fingers. Body oils and salts reduce solderability, promote corrosion and dendritic growth. They can also cause poor adhesion of subsequent coatings or encapsulates.</li><li>Do not use hand creams or lotions containing silicone since they can cause solderability and conformal coating adhesion problems. </li><li>Never stack electronic assemblies, or physical damage may occur. Special racks may be provided in assembly areas for temporary storage.</li><li>Always assume the items are ESDS (Electrostatic Discharge Sensitive) even if they are not marked.</li><li><p>Personnel must be trained and follow appropriate ESD practices and procedures.</p></li><li><p>Never transport ESDS devices unless proper packaging is applied.</p></li></ol><h2><br />Parylene Adhesion Tests </h2><p>Regarding customer projects, we never make any assumptions, no matter how optimized or streamlined the process is. <em>Test everything</em>. We use cross-hatch testing internally to ensure our coating bonded well. <br /><br />Cross-hatch testing is a widely used method for evaluating the adhesion strength of coatings to a substrate. This test involves making precise cuts in the coating, typically in a grid or cross-hatch pattern, using a sharp blade or specialized cutter. After scoring the surface, adhesive tape is applied and quickly removed to assess how much the coating detaches. The adhesion is then rated based on the percentage of coating removed, with classifications ranging from excellent adhesion (no coating loss) to poor adhesion (significant peeling or flaking). Cross-hatch testing provides a quick and reliable way to assess coating durability and performance, ensuring that coatings meet quality and industry standards before being subjected to real-world conditions.</p><h2><br />A Good Cleaning Process Brings Parylene to Life</h2><p>When people contact us about Parylene coating, it's typically about a property they’ll need to meet a spec or solve a problem. For example, they need superior corrosion resistance. They'll also need good adhesion, which means they'll need good surface prep. <br /><br />My team and I work daily to bring customer visions to life through streamlined, dependable processes. Our problem-solving skills save our customers money and time and enable and enhance our amazing technology at HZO. <br /><br />In the coming months, I'll share more about how you can use the process to do the same for your company. Of course, I can't share the custom solutions we've developed for our partners, but I'm happy to provide value where I can. <br /><br />Do you have questions about process engineering in Parylene or surface preparation?
