Rigid Flex PCB

Rigid Flex PCB have been used in the military and aerospace industries for more than 20 years. In most Rigid Flex PCB, the circuitry consists of multiple flexible circuit inner layers selectively attached together using an epoxy pre-preg bonding film, similar to a multilayer flexible circuit. However, a multilayer rigid flex circuit incorporates a board externally, internally or both as needed to accomplish the design.

High level benefits of rigid flex circuits are as follows:

• Better reliability, signal integrity, noise reduction, and impedance control
• Reduces mechanical space and device weight
• Improves design freedom
• HDI microvia
• Cost-saving alternative to multi-layer FPC
