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.
the substrate. Chemical etching divides the copper into separate conductive lines called tracks or circuit paths, pads for connections, metallized holes (vias) board Rigid-Flex for passing connections between layers of copper as solid conductive areas for electromagnetic shielding or other purposes. Each of the conductive layers is designed with copper tracks (similar
or unwanted electrical contact with possible loose wires. board Rigid-Flex For its function of helping to prevent solder shorts, the coating is called a solder mask. Soldermask is generally green in color but can have different colors: green, red, blue, white, black. Only the outer layers need to be covered with solder mask, the inner
The longer the route or the higher the frequency, the better adaptation is required. When producing the printed circuit with controlled impedance, the impedance will be controlled by acting on the dimensions of the tracks and the distance between them, i.e. the insulation. For a board Rigid-Flex multilayer printed circuit with a specific
