There are many high level benefits to Rigid Flex circuits including:
Connection Reliability – Connecting rigid layers with flexible cables is the foundation for combination rigid flex circuits. Rigid flex constructions eliminate the need for board-to-board connectors or wiring harnesses to link rigid boards together.
Five Layer Rigid Flex
Five Layer Rigid Flex
Lower Part Count – Compared to a traditional rigid board, rigid flex circuits require fewer parts and interconnections by eliminating wire harnesses and board-to board connectors.

FQA
1. Rigid-flex PCB vs. rigid PCBs and flexible PCB, What are the differences?
As the name suggests, rigid-flex PCB is a mixture of rigid and flexible PCBs.
Rigid-flex PCBs combine the excellent qualities of both while eliminating many of their limitations.
Rigid-flex PCBs combine flex circuit design with rigid materials.
By layering the flexible PCB board inside the rigid printed circuit board material, the versatility of the flexible printed circuit is finally combined with the stability, strength, and circuit wiring density of the rigid printed circuit board.
This mixing opens possibilities for more complex and mechanically challenging rigid-flex PCB designs.
Rigid-flex PCB simplifies the electronic design by eliminating flexible cables, connectors, and discrete wiring.
Its electrical performance has been enhanced compared to its counterparts because the circuit is an integral part of the overall structure.
All electrical and mechanical connections are contained in the rigid-flex PCB, providing electronic designers with greatly improved service reliability and electrical performance.
Although the cost of rigid-flex PCBs is usually higher than flexible PCBs and rigid PCBs.
However, rigid-flex PCBs’ reliability, weight reduction, strength, and space-saving advantages are generally ideal in specific applications and are superior to any other electronic packaging technology.
Ultimately, rigid-flex PCB provides the best benefits of rigid PCBs and flexible PCBs in one solution.
