Flex boards with stiffener are formed by a flexible part of polyamide material to which a rigid material of FR4 is attached.
of material are laminated together in an alternating sandwich: copper, substrate, copper, substrate, copper, etc.; each layer with board Flexible stiffener of copper is etched and any internal sleepers (which will not extend to both outer surfaces of the finished multilayer board) are plated before the layers are laminated together. FR-4 epoxy
yellow, black, blue, red. Screen printing is used to render useful information on the PCB board that can help Flexible board with stiffener users during assembly. It is used to mark component values, part numbers, test points, polarity, etc. Screen printing does not influence the printed circuit and the possible problems that may appear may be slight
paths, pads for connections, metallized holes (vias) for passing connections between layers of copper as solid conductive areas Flexible board with stiffener for electromagnetic shielding or other purposes. Each of the conductive layers is designed with copper tracks (similar to wires on a flat surface) that provide electrical connections on that conductive layer. Another
