Why do circuit boards need copper cladding?
Generally, there are several reasons for copper cladding. 1.EMC. For large-area ground or power copper cladding It will play a shielding role. Some special grounds, such as PGND, play a protective role. 2.PCB process requirements. Generally, in order to ensure the electroplating effect or lamination deformation, copper is laid on PCB layers with less wiring….
