Flex PCBs & Rigid Flex PCBs
 

Flex PCBs, also known as flexible printed circuits or flexible electronics, provide greater options for designers and engineers when assembling electronic circuits.

 

They are constructed from flexible, high-performance plastic material, usually polyimide, which enables the board to bend or "flex" during use. This flexibility opens them up to use in a wide range of applications.

 

Here are the most common types of flex circuit construction:

  • Single-sided flex PCB
  • Double-sided flex PCBs
  • Multi-layer flex circuits
  • Rigid flex PCB
  • Sculptured flex circuit board
