Multi layer, flexible pcb is 'world's largest'

UK firm develops ‘world s largest’ multi layer flexible pcbs

Gloucestershire based company Trackwise has developed a technique for manufacturing flexible printed circuit boards of any length.

For aerospace and other high value, mass critical applications, the pcbs can be used as an alternative to traditional wiring harnesses, offering space and weight savings of up to 75%.

Company md Philip Johnston said: "Flexible multi layer pcbs were originally developed in the second half of the 20th century as a replacement for wiring cable but due to length limitations the cable or harnesses replaced were typically internal to equipment rather than point to point harness replacement.

"Any longer runs of pcb would have to be made via intermediate connections, representing additional weight, cost and complexity as well as a source of potential unreliability. Our recent innovation means that these intermediate interconnects can be removed."

Trackwise is just one of more than 30 high tech companies in the Innovation Showcase at Venturefest Bristol 2012. For more info visit
