Rigid-Flex PCB Manufacturing Solutions
Rigid flex printed circuit boards are a hybrid of flexible and rigid board technologies. Depending on the application, most rigid flex boards are made up of multiple layers of flexible circuit substrates attached to one or more rigid boards externally and/or internally. Using rigid-flex PCBs has several advantages. Because they have a rigid layer that protects the flexible layer, they are more durable than traditional flexible PCBs. They also have a higher component density, allowing for the design of more complex circuits. Furthermore, rigid-flex PCBs can be bent or folded to fit into tight spaces, making them useful in applications where space is limited.
