Semi-flexible circuit boards

Printed Circuit boards that have partially flexible as well as rigid structures are termed semi-flexible or half-flexible boards. They generally cost less than so-called starrflex printed circuit boards and are preferred when only a few bendable cycles are required.

In the manufacturing process, the flexible areas are scored to a predetermined, exactly defined residual thickness, so that these correlate with the required and physically possible bendable needs and cycles.
