Design of Rigid Flex PCB

Rigid-flex PCBs utilize 3D design, allowing the circuit board to fold or twist to create the desired shape for the product.
Designing circuit boards in 3D allows for higher spatial efficiency, ideal for situations where reducing space and weight may be necessary.
Rigid-flex PCBs are typically thinner than other circuit boards, making them an excellent choice to meet any thin or lightweight packaging requirements your product may have.

The Advantages of Rigid Flex PCB

By eliminating the need for connectors and cables between individual rigid components, circuit board size and overall system weight can be reduced.

Compared to flexible boards, handling during assembly is easier, simplifying the PCB assembly process.

This greatly improves reliability, eliminating the need for delicate, fragile wiring that is prone to solder joint and connection issues.

              Rigid Flex PCB Assembly Process


The first step in the manufacturing process is to create the rigid-flex PCB stack-up. This involves laying down the flexible and rigid layers in their proper order.


Then, an assembler adds the components to a pick-and-place machine. This machine can identify and arrange both rigid and flexible components.


After placement, the components get laminated together. Then, assemblers remove excess materials from the rigid-flex board.


Finally, the assembler performs post-processes, such as applying finishes, soldering, and drilling. Once that’s finished, the rigid flex PCB is ready to package and ship.
