• Rigid Flex PCB Benefits and Applications

    Rigid-Flex PCB Designs guidelines By Altium Academy . Rigid flex PCB have been used in the military and aerospace industries for more than 20 years. In most rigid flex circuit boards 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.
