Flexible printed circuit boards (PCBs) are those, which have conductor patterns printed on a flexible insulating film. The rigid PCBs are responsible to hold all the components. The flexible film connects two rigid PCBs. Thus, rigid flex PCBs are a combination of both, rigid, and flexible PCBs. This is a permanent combination, meaning these two types of PCBs are permanently connected to each other. You can get custom manufactured asymmetrical rigid flex printed circuit boards having outward flexible layers, or symmetrical rigid flex PCBs with inward flexible layers.
If you are looking for experienced manufacturer of these rigid-flex PCBs, then we have you covered. Sierra Assembly is one of the well-known manufacturer of rigid flex circuit boards and we have the capability provide your designs based on your specifications and application requirements.
