P-Flex™ are flexible printed circuits that are manufactured by overlaying copper plating on printed silver circuits. In this technique, silver nano-ink is first printed on heat-resistant PET using inkjet printers, before electroless copper plating is applied over it. Conventional circuit boards hitherto are made by adhering metal to the entire surface before melting off the undesired areas. Elephantech, Inc. has since developed a unique manufacturing technique called Pure Additive™ that is a reversal of this conventional method. In their new method, metal nanoparticles are printed on the necessary areas only using an inkjet printer, before electroless plating technology is used to consolidate the metallic structures. As a result of this technique, “plates” that were necessary in the conventional method have become redundant, and this optimization of materials and processing operations has led to a tremendous reduction in cost and lead times. P-Flex™ is expected to find its way into a wide variety of small-lot productions and trial manufacture processes. ※MTRL TOKYO (FabCafe MTRL) provides and installs free samples.
