Rigid-Flex PCB - A Perfect Modern Connection Solution for Circuits
Overview of Rigid-Flex PCB
- PCBONLINE is good at rigid-flex PCBs, a type of the most advanced boards. The rigid-flex PCB is a type of circuit board that combines the features of the rigid board and the flex board - it can be twisted, folded or rolled into the required shape at some points, and can maintain hard and stable at some points.
- Designed in 3D space, the rigid-flex PCB eliminates the solder joints and cables, which makes multiple material and design layouts possible.
- Given that rigid-flex PCBs have greater spatial efficiency, they benefit all electrical applications and are widely used in the electronic products.
Advantages of Rigid-Flex PCB
Why Choose Rigid-Flex PCB from PCBONLINE
- • We use the best materials with a good heat/sweat/chemical resistance to manufacture rigid-flex PCBs.

- • We can produce custom rigid-flex PCBs at any volume as per you required, for mass production, small-batch prototypes, commercial purpose, and hobby-level services, etc.
- • Our professional team can provide advice for free if there's any problem in your layout.
- • We can provide one-stop service including rigid-flex PCB layout, electronic components, PCB manufacturing & assembly, and your final product assembly.
Rigid-Flex PCB - Manufacturing and Tech Specs
Materials & Equipment for Manufacturing
- Materials: For the flex material to make the soft part, PCBONLINE chooses the kind of smaller size and film - Kapton, which has excellent flexibility, great high-temperature/sweat/weather/chemical resistance, high hygroscopicity, good electrical and mechanical properties, and good flame retardancy.
- For the polyester imide (PI), PCBONLINE chooses DuPont, which is made in America.
Equipment:
The requirements for rigid-flex PCB production equipment are higher than those for the FPC and the regular PCB, and PCBONLINE's equipment is at an advanced level.
A.Drilling equipment: we use the advanced ESI UV laser drilling machine and the Hitachi CO2 laser drilling machine.
B. Printing equipment: we use the laser imaging machine and automatic exposure machine.
C.Automation equipment: we use the VCP plating line, the automatic reinforcing laminating machine, and the automatic laminating machine.
Manufacturing Process
Rigid-flex PCB Layout:
The PCB layout is an important process before the PCB manufacturing. The design is different according to your need, but three aspects need considering: 1) spatial efficiency; 2) stackup design; 3) high performance relationships. If you need us to design the PCB layout for you, we can make sure that there is coordination in designing and fabrication portions.
PCB Manufacturing:
Step 1. Cut lamination
The flexible part: we will prepare the adhesive, polymide, flexible materials respectively. The rigid part: we will also prepare the rigid material for the next process.
Step 2. Process the above four materials
In this step, we will press fit holes on the adhesive and polymide respectively, and make the inner layer out of the flexible and rigid material respectively.
Step 3. Laminate into stack-up
We will place the above processed materials in appropriate positions accurately and laminate them into the stack-up. Then the frame of the rigid-flex board is built.
Step 4. Finish the outer layer
We will finish the outer layer and its following steps.
