Stack-up for FPC

The following is the usual FPC stackup information. If you need custom FPC stackup, please make note and we will manufacture according to your requirement.
Polyimide (PI) is the most commonly used thermal curing insulating material in flexible circuit processing. The thickness range of the material is generally 12.5μm (0.5mil) and 125μm (5mil). Divided into with glue and without glue, the DK with glue is 3.5, and the DK without glue is 3.3.
