Aerospace Flexible Printed Circuits

Reducing the weight of cables in aircraft by up to 60% can significantly lower fuel consumption and costs while also contributing to a decrease in carbon emissions. Amphenol Trackwise’s unique manufacturing capabilities are designed to help achieve these weight savings.

Why flexible printed circuits are ideal for Aerospace?

Flexible multilayer PCBs can offer significant benefits over conventional aerospace harness technology and wiring harnesses, including:

Our patented process allows us to manufacture flexible multilayer printed circuit boards of any length.  Currently, the longest requested by a customer has been more than 72 metres / 236 feet in length, making it the world’s largest flexible multilayer PCB.

Trackwise’ unique patented manufacturing process has been developed to enable the production of multilayer, flexible printed circuits of any length. This patented^* process is called Improved Harness Technology ^TM (IHT).

Flexible multilayer PCBs were initially designed in the mid-20th century to replace traditional wiring.  However, they faced limitations in length and needed intermediate connections for extended runs. These connections, combined with the inherent weight of wiring, contributed to increased overall weight, cost, complexity, and the risk of unreliability. 

All the benefits of Twisted Pair, but using Flex Printed Circuits

If your project required LVDS, twisted pairs can be represented in length unlimited FPCs whilst maintaining all the benefits of traditional wiring including reduced AMI and improved signal integrity.
