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.

Ultra-Precise Deposition for the Fabrication of Next-Generation MicroLED and QD-LED Displays

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.

Additive and high-throughput nanoscale multi-layer printing materials and devices on any substrate?

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.

Printed battery technology: thin, flexible, and low cost for everyday objects

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

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:

How to screen print sub 30um features?

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.

Additively manufactured FPCBs with bulk-like conductivity and soldering?

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
