Flexible PCB

Flexible printed circuits board (Flexible PCB) is a kind of electronical conductors with conductive pathway printed on a bendable film that acts as an insulating (dielectric) base material and coated with a dielectric cover layer on the top. Depands on your interface requirements, the Flexible PCB can be developed using polyester or polyimide (Kapton) as the base material.

The structure can be rigid or flexible to reduce interconnection and incorporate tails directly into the circuit. Flexible PCB can be designed from simple single layer copper flex on polyester(single layer FPCB), to complex double sided on polyimide(double layer FPCB), and even intricate multi-layer composition.

  • Single Sided Flexible PCB
    Single Sided Flexible PCB
    Single layer Flexible PCB consisted of one conductive layer, suitable when space is limited.
  • Double Sided Flexible PCB
    Double Sided Flexible PCB
    Double layer Flexible PCB is make of two conductive layers with an insulating layer between. It is a ideal product when circuit density is required.
  • Multi Layer Flex
    Multi Layer Flex
    The multi-layer flex is the FPC combines either single sided Flexible PCB and double sided Flexible PCB. It's a efficient solution when met the unavoidable crossovers.
