At the recent printed Electronic conference staged by IDTechEx in Dresden Germany, Koichi Mizugaki of SEIKO EPSON Corporation described how SEIKO EPSON has been working on the manufacture of Printed Circuit Boards through inkjet printing. Koichi Mizugaki introduced

He said the desktop electronic factory is on the way and summarised the benefit of the inkjet route as follows:
