Normally, the rigid parts which is made of FR4, is from one layer to multi layers. The vital parts is the flex circuits which connect the Rigid PCs, and it is one layer or multi layers. Right now, we can make the rigid-flex circuits over 10 layers.
Rigid-flex PCB is differentiated from multi-layer circuits with stifferners by having conductor on the rigid layers. Plated through holes (PTH) extend through both rigid and flexible layers.
BEST CO., LTD. provide various sizes of Rigid-Flex Circuit boards, of different layers. All Rigid-Flex Circuits are tested with flying-probe testing machine reflecting all Gerber data to insure continuity and other data requirements. We can provide fast prototype, on time delivery, great quality for you. We can also do SMT/SMD as per client request. Please contact us today for more information about rigid flex circuits.
