Rigid-Flex PCB Manufacturer
A rigid-flex printed circuit board (PCB) is a type of PCB that combines the advantages of both rigid and flexible PCBs. It is made up of a combination of rigid and flexible layers, which allows it to be both rigid and flexible in different areas.
Rigid-Flex PCB Manufacturing Solutions
Rigid flex printed circuit boards are boards that use a combination of flexible and rigid board technologies. Most rigid flex boards consist of multiple layers of flexible circuit substrates attached to one or more rigid boards externally and/or internally, depending upon the design of the application.There are several benefits to using rigid-flex PCBs. They are more durable than traditional flexible PCBs because they have a rigid layer, which helps to protect the flexible layer. They also have a higher density of components, which allows for more complex circuits to be designed. In addition, rigid-flex PCBs can be used in applications where space is limited, as they can be bent or folded to fit into tight spaces.

The received assembled PCB's worked flawlessly. The placement of the parts is excellent. I had a very good contact with Mis wang the WINOW engineer who took care of our project. She asked the right questions to make sure the project was finished correctly. We had a very pleasant communication, fast and to the point.
This board is needed to charge the lipo batteries of my robotic platform (rover). First time order with excellent communications throughout the ordering, manufacturing progress and up to delivery tracking. Very good price especially the first order with a discount credit.
Boards arrived yesterday and got started on assembly. Excellent, solder wetting, clean line
definition, via drill holes exactly in the middle of via lands.
Please pass my thanks back to one and all who made such excellent boards.
