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.

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.

If you are looking for more information about flex circuit construction methods, we recommend seeing our technical article on the latest material and construction methods provide the highest quality rigid-flex PCBs.
