A unique new approach of printing functional materials with unparallel precision and repeatability. Technology called Ultra-Precise Deposition (UPD) is a nanodispensing method capable to print high density and high viscous materials with the resolution down to 1 µm in feature size and with high ratio of width to height after single pass. For this method material extrusion is controlled by a pressure, which means it is not supported with high electric field. Thanks to this there are no limitation if the substrate is conductive or dielectric.
Nano-Ops is commercialising an automated wafer-based process and fab-in-a-box based on the directed assembly technology which can 'print' features down to 20nm. Here, In the first step a pattern is first etched into a template wafer.
Printed batteries offer thinness and flexibility, enabling new applications, but their production is deceivingly complex. Gunter Hübner from Stuttgart Media University offered some insights at the e-Swiss conference last week.
Experimenting in the world of Flexible Hybrid Electronics (FHE) comes with a variety of hurdles. Printing technologies are vastly different in terms of materials compatibility and have pros and cons that make them suitable for particular applications. Choosing materials that match the printing technology you intend to use is the most important decision you’re going to make. But what if one could print, digitally, using any paste and ink on any substrate? Read more
Why can microLED technology can help narrow the energy gap in electronic devices? The first slide shows the battery gap- Ahmed (Intel) has collected data by year showing that power demand of phones far exceeds the power supply level of batteries, creating a "battery gap" which ...
Phosphors or QDs for color conversion in LCD and microLED ? Which will win? This is an evolving technology space to watch. Here, it is shown that phosphor technology is evolving, enabling not just red but also green narrowband color conversation with small particle sizes compatible with microLEDs
Molecular particle free inks can offer extreme formability and stretchability, allowing the design and production of 3D shaped and/or in-mold electronics parts with extreme curvatures and complex shapes.
How to overcome the traditional limits of LDS (laser direct structuring) to metallize 2D and 3D objects made from all kinds of surfaces?
Gallium-Indium-Tin is an interesting material for stretchable electronics. It can be formed into a non-toxic RoHS-compliant gel and applied to almost any substrate to form stretchable conductive metallizations and circuits.
Screen printing never ceases to advance and is entering into ultrafine line printing territory. FERNANDO ZICARELLI explains in this short 5-min talks important considerations to achieve fineline printing and further push the resolution down:
Here, the additive nature of the process means that the production process is environmentally friendlier and does not involve etching chemicals. Furthermore, the digital nature of the patterning (inkjet printing) means that designs can be changed faster.
We first discuss emerging and existing applications for ultra fineline screen printing, outlining how evolution of screen printing can unlock various electronic applications. Next, it will review other printing technologies extending the linewidth resolution to sub-micron range
