Characteristic Of Rigid-Flex circuit
The use of Rigid-Flex circuit boards can reduce the total cost of the final product.
The rigid-flex circuit is a multilayer printed circuit board with both rigid and flex electric interconnecting layers. The composition of flexible and rigid substrates in a single circuit board creates unique opportunities. The technology allows designers to replace multiple PCBs interconnected with connectors, wires and ribbon cables to create a single circuit board while improving performance and reliability. Furthermore, because rigid-flex circuit PCBs can be bent, folded or twisted, they make an ideal solution for optimizing applications with tight space limitations by using the third dimension.
