What is Rigid-Flex PCB?

The inflexible PCB and FPC are incorporated by pressing according to the demands, comes out a special circuit board with the benefits of stiff PCB and FPC, which is called inflexible rigid flex PCB.

Since the rigid flex boards have both flexible areas and rigid locations, they certainly supply great help to save the inner spacing, lower the quantity, as well as boost the efficiency of the products.

Because of these advantages, rigid flex PCBs are gradually becoming the core electronic parts of premium digital products.

Rigid Flex PCB Advantages

☆Smaller and complex structure

☆Reduce board size and weight

☆Reduce parts count

☆Reduce parts count

☆Easier for SMT compared to FPC

☆Modular interfaces (ZIF)

☆Simplify testing conditions

☆Reduced freight & assembly costs

☆Unleash the creativity of case design
