(Printedcircuitboard, referred to as PCB) is a substrate for assembling electronic parts. It is a printed board that forms point-to-point connections and printed components on a general substrate according to a predetermined design. The main function of this product is to enable various electronic components to form a predetermined circuit connection, play a role in…

1.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….

Via is one of the important components of multi-layer PCB, and the cost of drilling usually accounts for 30% to 40% of the cost of PCB board manufacturing. Simply put, every hole on the PCB can be called a via. From the perspective of function, vias can be divided into two categories: one is used…
