What is rigid flex pcb board?
Rigid-flex PCB board, it is a circuit board that combines flexible and rigid circuit board technology in the application. Most rigid-flex boards are composed of multiple layers of flexible circuit boards, which are attached to one or more rigid boards from the outside and/or from the inside, depending on the design of the application. The flexible substrate is designed to be in a constant deflection state, and is usually formed as a deflection curve during rigid flex pcb manufacturing or assembly.
Hitech rigid flex pcb manufacturing process
After the production of FPC flexible boards is completed, the production of Hitech rigid flex pcb boards can be completed through the following processes.
- Punching
Drill holes on FR4 and PP film, and the design on the alignment hole is not the same as the general through hole. After the punching is completed, browning is required.
- Riveting
Laminate copper clad laminates, PP adhesives, and FPC circuit boards and place them neatly. The original old process is to laminate and pressing step by step, but it is a waste of time. After many attempts, we found that the stacking process can be completed once.
- Laminate
This is a relatively complete step in the production of rigid-flex pcb board. Most of the materials are integrated for the first time. First, the bottom layer is copper clad laminate and PP film, above are the FPC flexible board produced in the previous process, and a PP film is placed on the FPC flexible board, then place the last layer of copper clad laminate. All materials to be laminated are placed in order and pressed together.
- Trimming
That is to remove the part of the circuit board where there is no circuit at the edge of the circuit board currently and in the future. Afterwards, it is necessary to measure whether the material has excessive expansion and contraction. Because the PI used in the production of flexible boards is also expansion and contraction, this has a very large impact on the production of circuit boards.
