Flex PCB boards or flexible printed circuit boards, as the name suggests, carry out the function of regular PCB boards while being physically flexible.
Polyimide PCB is a printed circuit board made of polyimide material. Polyimide is a lightweight, flexible material with excellent electrical properties and low thermal expansion.
For very advanced devices that require very limited spacing or continuous movement, we need to use multi-layer flexible PCBs, This type of flexible PCB has three or more copper layers.
