Characteristic Of Rigid-Flex circuit

Use of Rigid-Flex circuit boards can reduce the total cost of the final product.

Rigid-flex circuit is a multilayer printed circuit board with both rigid and flex electric interconnecting layers. A 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.

Embedded Flex “e-Flex”: comparison to HDI/ELIC Rigid-flex circuits.

• Compatible with Rigid PCB stacked vias processing
• Retains dynamic flex, rapid prototyping, and improved panel utilization
• Proprietary technology requiring license and technology transfer limits availability
