Rigid-Flex boards are printed circuit boards that are formed by areas of rigid parts made of FR4 material linked together with areas of flexible parts made of polyamide material with different thicknesses.
or other purposes. Each of the conductive layers board Rigid-Flex is designed with copper tracks (similar to wires on a flat surface) that provide electrical connections on that conductive layer. Another manufacturing process adds plated or metallized holes that allow interconnections between layers. PCBs mechanically support electronic components using pads for bonding the component terminals and
Electronic computer aided design software is available to do much of the layout work. Multilayer PCBs allow for much higher component density because the component paths on the inner layers would occupy the space between the components. The increase in the need for multilayer printed board Rigid-Flex circuit boards with more than
and length, must be small enough for the current the conductor will carry. It is recommended that the Rigid-Flex board power and force paths be larger than the signal paths. In a multi-layer board, an internal layer may be mostly solid copper to act as a ground plane for shielding and
