Product Details

Double sided flexible circuit (FPC) consists of double-sided copper clad material with top and bottom cover films (PI or Green/Yellow Oil, Carbon Ink, etc).  Two conductive layers with an insulating layer between, plus conver layers on outer layer. The cover films are pre-routed to access copper from both sides using plated thru holes(PTH).

Characteristics of product

  • This is the FPC that turns on the electric current in circuits on front and rear sides by through-hole plating.
  • More complex wiring is available than single sided FPC.
  • As the parts can be mounted on both surfaces, it is possible to use the space effectively.
  • The minute part to be mounted on surface can be mounted without reinforcing board.
