Frequently Asked Questions

What is a flex-rigid PCB and how does it differ from a standard PCB?

A flex-rigid PCB combines flexible polyimide sections with rigid FR4 layers into a single integrated board. Unlike standard rigid PCBs, it can be bent, folded, or shaped in three-dimensional space, enabling compact designs that eliminate separate connectors and cables. This reduces assembly errors, lowers overall weight, and improves reliability in demanding applications like medical devices and aerospace electronics.

How many layers can a flex-rigid PCB support?

What base materials are used in flex-rigid PCB manufacturing?

What surface finish options are available for flex-rigid PCBs?

What quality standards do your flex-rigid PCBs comply with?
