High precision, the position accuracy and dimensional accuracy of the leak hole on the formwork are guaranteed. The precision of the laser machine itself is very high, the X and Y axis precision can reach 3um, and the repeatability can reach 1um. And because the data adopts computer design files, the computer is directly driven, which reduces the possibility of deviation in the process of light drawing and graphics transfer. , especially for large-format circuit boards, this advantage is more prominent.
