Rigid Flex PCB Manufacturing from 2 to 30 Layers

"Designed in 3D space, rigid-flex PCBs eliminate the board-to-board connectors,
which makes multiple designs possible."

What is Rigid Flex PCB

Rigid-flex PCBs essentially are flexible PCBs that have rigid FR4 PCB layers. The flexible section is the internal FPC layers of the rigid-flex PCB, and rigid FR4 PCB sections scatter on the top and bottom. The exposed flexible PCBs are positions that require the flexibility of products.
The rigid FR4 sections and the flexible section are electrically interconnected. And copper used for the FPC section has to be rolled copper.
How do we fabricate rigid-flex PCBs?
We fabricate the flexible PCB layers and rigid FR4 PCB layers first. On the rigid layers, the areas for the exposed FPC are without circuits. Second, we laminate the flexible layers and rigid layers and then laser cut to remove the unwanted rigid FR4.

Rigid Flex PCB Available Structures

rigid-flex PCB structure
Symmetrical rigid flex PCB construction - the board is manufactured with inward symmetrical flex layers. Capability is from 3R+1F to 24R+6F.
Asymmetrical rigid flex PCB construction - the board is manufactured with outward asymmetrical flex layers. Capability is from 2R+1F to 24R+6F.
HDI multilayer rigid flex PCB construction - the board's rigid section is with blind/buried mirovias. HDI capability is 4+N+4.

Advantages and Applications of Rigid Flex PCB

Advantages of rigid flex PCBs are dynamic and mechanical stability, space-saving, simplified installation, freedom of 3D design, reduced overall product weight.
Applications of rigid flex PCBs range from aerospace & defense systems to computers, smartphones, and cameras, especially products with a compact space.
