Common Flex & Rigid-Flex Circuit Board Material Stack-Up

Below you will find various flex and rigid-flex PCB stack-ups ranging from 4-layers all the way up to 12-layers. With these stack-ups, we can support a wide variety of alternatives, from single to multiple airgaps, uneven flex layer counts, and a singular flex section. Here is a blog post on Flex PCB Stack-up Documentation.

Beyond this, we can also support rigid-flex stack-ups all the way up to 18-layers. For stick-up questions, requests, and feedback, feel free to contact us and we will refer you to our flexible circuits product manager to assist in creating the stack-up that best suits your design needs.
