Rigid-Flex PCB Series

3layer Rigid-Flex PCB

At PCBMay, we design and manufacture a wide range of standard and custom rigid-flex printed Circuit Boards. The 3 layers rigid-flex circuit board comprises a single flexible layer and two rigid layers. This type of rigid-flex PCB is designed to create a dynamic interaction between the circuit board and the electronic product in which it is used.

4layer Rigid-Flex PCB

PCBMay offers 4 layers of rigid-flex PCB with 2 layer flex PCB in breakaway panel form, where the breakaway panels are created using the tab routing. These panels are designed such that they do not sag during reflow or wave soldering. These panels remain attached to the PCB during the assembly process and are removed just before the inspection phase.

5layer Rigid-Flex PCB

PCBMay provides rigid-flex printed circuit boards in various standard and custom specifications. These printed circuit boards are used regularly in industries such as power, automobile, telecommunication, and lighting. PCBMay’s 5layer rigid-flex printed circuit boards have gained popularity over the years. These printed circuit boards are known to offer flexibility.

6layer Rigid-flex PCB

PCBMay can provide single, as well as multilayered printed circuit boards, among which 6 layer rigid-flex PCB with stiffener is the most popular one. The stiffeners are added to the PCBs to improve their strength and durability. They help to support the PCB in the manufacturing phase by minimizing the deflection.

7layer Rigid-Flex PCB

7layer Rigid-Flex PCB comprises 7 layers and is made from FR4+polymide. The polyamide material helps improve rigidity, flexibility, and toughness. We can provide this printed circuit board in maximum panel size 18″*24″, and thicknesses of 0.5mm~3.2mm, surface finished: Immersion gold, LF HASL, Immersion Silver, and Immersion Tin.

8layer Rigid-Flex PCB

PCBMay is committed to offering rigid-flex circuit boards quickly and consistently without sacrificing quality. Our engineering team can work with customers who demand nothing short of perfection. With years of effort in the field, we have gained expertise in producing several kinds of PCBs, and one of the types we offer is 8 layer rigid-flex PCB.

Rigid-Flex PCB By Copper (5)

  • 0.5oz Rigid-Flex PCB

    This is 4 layer rigid-flex PCB, 1oz copper for outer layer and 1/2oz for inner layer, surface finish is immersion gold, 1.6mm(rigid parts) and 0.13mm (flex parts) for thickness, whose application is medical device.

  • 1oz Rigid-Flex PCB

    PCBMay 1oz Rigid-Flex PCB is the standard copper for your project. You will send your RFQ to us, we love to offer good price and delivery time for you, meanwhile, our engineering team will give you some suggestion.

  • 2oz Rigid-Flex PCB

    2oz copper is 75um copper, PCBMay can manufacture 2oz for inner layer and outer layer of the rigid-flex PCB. If you have any engineering questions, please email them to us, we’d love to help you all the time.

  • 3oz Rigid-Flex PCB

    Do you have 30z copper of rigid-flex PCB? Typically, the Min. trace width/space is 0.25mm/0.25mm for mass production, if it’s a prototype, PCBMay can make 0.2mm/0.2mm for the Min. trace width/space.

    4oz copper is heavy copper, which is not normal for the rigid-flex PCB, but PCBMay can manufacture it for you. Typically, the applications are power supply from aerospace, automotive or the charge of the cars.

Rigid-Flex PCB By Colors (5)

  • Green Rigid-Flex PCB

    You often see the green color of the rigid-flex circuit boards in the PCB industry, which is the same as rigid PCB. There are many different applications such as medical devices, military & defense, automotive, ect.

  • Black Rigid-Flex PCB

    You might see the black rigid-flex PCB, the actual color of the PCBs is soldermask, not PCB itself. One of the main reasons why the solder mask remains black is that such circuits do not require the reflection of light.

  • Blue Rigid-Flex PCB

    As a reliable PCB manufacturer in China, PCBMay can produce different colors of the rigid-flex PCB, such as blue color. We have rich experience and knowledge to manufacture these blue rigid-flex PCBs for you.

  • White Rigid-Flex PCB

    Typically, the white PCB is just for LED lighting, because this color looks very pure and makes the light is very bright. As for the white rigid-flex PCB, they’re used in the lighting of medical operation devices.

  • Red Rigid-Flex PCB

    Red soldermask is easy to distinguish from other colors, what’s more, it depends on the designer of the project. This is 8 layer rigid-flex PCB, thickness 2.0mm(rigid part)+0.2mm(flex part) and surface finish ENIG.
