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….
