Sierra - Flexible Printed Circuit Boards (Pcbs)
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.

There are a number of benefits of using the rigid flex printed circuit boards, and this is why these boards find their use in a wide range of applications. The following are some features that prove to be beneficial:
- The entire process of printed circuit board assembly is simplified.
- Lesser number of solder joints are required in a rigid flex PCB. This increases the connection reliability.
- The circuit design of a rigid flex board is streamlined. This helps reduce the overall package space. The weight of the package is also reduced.
- The total PCB costs and expenditure is reduced considerably by using these circuit boards.
All the beneficial features explained above, make these circuit boards ideal for use in a wide range of applications. Some most common applications of these PCBs include:
- Digital Cameras
- Military Weaponry
- Cell Phones
- Aerospace Systems
