World's First Ultra-Thin Multilayer Circuit Board

Posted by Hemos on from the first-to-the-post dept.

neutron_p writes "Seiko Epson has developed the world's first 20-layer circuit board. Multilayer circuit boards are normally produced by using a photolithography. However, the industry has struggled to produce thin, lightweight, high-density multilayer circuit boards. Seiko Epson uses an inkjet-based manufacturing process, which has many advantages over a traditional photolithography process."
