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.
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 Rigid-Flex board inner layers would occupy the space between the components. The increase in the need for multilayer printed circuit boards with more
has the role of a reference indicator for the components on the PCB. Graphics and text on a circuit board's PCB are usually printed with a non-conductive permanent epoxy ink. The color is usually white, although other colors are board Rigid-Flex available: yellow, black, blue, red. Screen printing is
flat sheet of insulating material FR4, Rogers or Polyamide for flexible circuits, and a layer of copper foil, laminated to the substrate. Chemical etching divides the copper into separate conductive lines called Rigid-Flex board tracks or circuit paths, pads for connections, metallized holes (vias) for passing connections between layers of
