4 Layers Rigid Flex Circuit Boards Fast Smt Contract Manufacturing

PCBA Capability

A rigid flex printed circuit board (PCB) is a hybrid circuit board design that integrates elements from both hardboard and flexible circuits. Rigid flex PCBs are rigid at some points on the board and flexible at others. Because of this, rigid flex circuits can be folded or continuously flexed while maintaining the shape of areas that need extra support. The circuits are typically multi-layered and are comprised of flexible circuit substrates joined with rigid boards. The flexible layers are buried internally and completely penetrate the rigid sections of the PCB.

Available structures for rigid flex PCBs

There are numerous, different structures available. The more common ones are defined below:

Traditional rigid flex construction (IPC-6013 type 4) Multilayer rigid and flexible circuit combination containing three or more layers with plated through holes. Capability is 22L with 10L flex layers.
Asymmetrical rigid flex construction, where the FPC is situated on the outer layer of the rigid construction. Containing three or more layers with plated through holes.
Multilayer rigid flex construction with buried / blind via (microvia) as part of the rigid construction. 2 layers of microvia are achievable. Construction may also include two rigid structures as part of a homogeneous build. Capability is 2+n+2 HDI structure.

Rigid Flexible PCB that we made for customers:

How can we guarantee quality? We do these actions to meet quality

1. 100% IQC check for all material incoming
2. Factory used ERP system to control lead time and quality , customer drawing (with size and spec.) will come with lot card on online board.
3. All Inner layer will do 100% AOI , and use plastic sheet between core to avoid scratch .
4. After lamination board we will do a cross section to Test board thickness and dielectric thickness .
5. On drill hole process , we use hole film to compare the board to Avoid hole missing or hole too big
6. On process , we would do cross section to Make sure hole wall copper .
7. For outer layer circuit , we do 100% AOI checking . for HDI board ,we would test board before solder mask
8. On solder mask process , we have inspect the board solder mask 100% .
9. 100% to testing finished board , if there is impedance control , we will do impedance control.

10. For production board , we would do first article board first .
