This paper reviews the definition, construction and benefits of flexible printed circuit boards, before looking at traditional and emerging applications that are now possible due to a Trackwise innovation that enables the globally unique manufacture of multilayer flexible printed circuits of unlimited length.

With the development of advanced flex PCB manufacturing solutions, such as provided by Trackwise’ Improved Harness Technology™ ( length unlimited multilayer flexible printed circuits), the paper re-examines the comparative benefits of flex PCB and twisted pair cable, specifically with regard to data cabling for high speed, low noise applications.
