The trend of multi-layer, functional, integrated and light, thin, short and small in PCB design and manufacturing has put forward more requirements and challenges for PCB design and manufacturing. The drilling process is an indispensable and very important process in the manufacturing process of printed circuit board.

With the tremendous impact of new technologies such as 5g, Internet of things and artificial intelligence on the electronic world, the PCB manufacturing industry has made a lot of development. New trends in PCB development are catching up quickly. It is estimated that the global PCB market scale in 2023 will be about US $70-75 billion.

For PCB printed circuit board drilling, the upper and lower backing plates are used to prevent the copper foil on the surface and bottom of the circuit board from blooming and generating burrs, so as to make the drilling surface of the circuit board smooth, improve the quality of PCB printed circuit board and improve the yield.
