The PCB mbadamba is generally glued together by several layers of resin material, and the internal copper foil is used for wiring, and there are 4, 6, and 8 layers. Among them, drilling occupies 30-40% of the cost of printed circuit boards, and mass production often requires specialized equipment and drill bits. Good PCB drill bits use good quality cemented carbide materials, which have high rigidity, high hole position accuracy, good hole wall quality, and long life.
