Two Surface Finishing Methods that Protect Copper of 8 Layer Rigid-Flex PCBs
As the name implies, 8 layer rigid-flex PCBs are manufactured with 8 conductive copper layers. If these copper layers are left unprotected, they started deteriorating leaving PCBs useless. Hence, in order to withstand the test of time, PCB manufacturers use reliable surface finishes to expand the service period of these crucial components. Amongst the several
