It is my opinion that the initial driving impetus for the development of stretchable circuits was a bit different than normal, meaning that military and aerospace have traditionally driven the development of arcane electronic interconnection technologies as they did with the development of both flexible and rigid-flex circuits. In contrast, it was a consumer-driven market that appears to have been the gate opener in the form of wearable electronics.
For the past year, I’ve talked about various aspects of developing a great vendor-customer relationship with your PCB fabricators from trust to confidentiality and sharing the future. Here are 10 questions to ask yourself when testing the strength of your current partnership with your vendor.
While flexible circuits continue their forward march, over the past decade, there has been increased interest and use of stretchable circuits for a variety of new applications where circuits have the ability to deform and/or elongate elastically and return to their original size. This upstart variation of the venerable flexible circuit has been given the title of "stretchable circuit," and it appears that they are going to be an increasingly important subset of future flexible circuit designs.
This article will present a hybrid manufacturing process to manufacture FHE systems with a two-layer interconnect structure utilizing screen printing of silver conductive ink, filled microvias to connect ink traces at the different layers, and use of the traditional reflow process to attach the semiconductor chips to the printed substrates.
July was a fun, productive month for IPC on the government relations front. Most notably, IPC’s workforce development efforts were recognized at the White House in Washington and on a factory floor in Michigan. On another front, we've launched an online platform that makes it easier for our members to contact their elected officials, and we’re using it to seek more R&D funding for an important industry project.
