Flexible Circuits are made from materials allowing for a non-planar positioning within the end product. Typical materials are polyimide-based, and can go under trade names such as Kapton (DuPont).

Applications for Flex circuits include products featuring repeated flex cycles (cellular phones, automatic doors).

They are also being used as connectors for LED-based lighting systems. Often, there are two components:

  • Metal substrate LED PCB
  • FR-4 based digital driver PCB
These two devices are often connected with a high profile and sometimes costly connector cable; however, a flexible PCB provides a lower profile, slimmer design, and higher reliability.
