Rigid-flex PCB

  • Flexible printed circuit board (Flexible PCB) is a common term that is synonymous with flexible circuits. While the term “FPCB” is generally used to describe rigid printed circuitry, “flexible PCB” is a little contradictory because “boards” aren’t really flexible. Some companies, like All Flex, design and manufactures flexible PCBs, but not rigid PCBs.
    There are many similarities between the two, but also significant differences.

  • 4L Rigid flex printed circuit board

    Rigid flex PCB circuit are a hybrid construction flex circuit consisting of rigid and flexible substrates which are laminated together into a single structure. Each layer of rigid-flex circuit are electrically interconnected by plated through holes (PTH), which is different from a flexible circuit with FR4/PI stiffener on top or bottom of flex circuit only by the means of preventive or thermal sensitive adhesive only, no PTH.

    Rigid-flex board enjoy the advantage of both rigid FR4 PCB and flexible circuits. In rigid area, components will be soldered on, and whole board can be bendable at the flexible circuit area, so that to save space of assembly, make whole product into a small size but with tight trace designing.

    Also people don't need to solder the FPC on PCB, or connect FPC on PCB via connector, furthermore, that plated through hole interconnection is more stable, firm than soldering or connector. So more and more rigid flex board circuit has been widely used in both military and civil area.

  • Flexible printed circuit boards and rigid flex circuit boards are highly durable, reliable, and allow you to design your circuitry to fit a device rather than building a device to fit the circuit board. That is why the design is created upon receipt of specifications that meet the purpose of the final product.
