substrate. Flexible-Rigid printed circuits are boards that bring in a unique combination of superior technology a flexible Storage conditions printed circuit made of a thin polyamide of 0.1-0.3 mm with a rigid printed circuit on an FR4 substrate. These printed circuits are used more and more lately, having the

green, red, blue, Storage conditions white, black. Only the outer layers need to be covered with solder mask, the inner copper layers are protected by the adjacent substrate layers. The soldering mask soldermask is made of a fluid substance like an ink and is applied in a thin layer similar to varnish on the

(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 conditions Storage using pads for bonding the component terminals and electrically connect them using traces of
