The laser template is processed by the laser cutting machine after the computer directly outputs the CAD file. It has the following characteristics:
◆ High precision, the position precision and size precision of the leakage 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.
◆ The processing cycle is short, 10,000 pads can be cut per hour, and as many as 15,000 round holes can be cut, and data processing and processing can be completed in one go. Due to the direct processing of data-driven equipment, the process between design and manufacturing is reduced, and it is possible to respond quickly to the market.
◆ Plan control, good quality consistency,. Stencil making is basically waste-free. At the same time, the defect rate of laser stencil printing is low, which is suitable for large-volume and automated SMT production needs.
◆ The hole wall is smooth, the roughness is less than 2um, and the opening can be made small at the top and big at the bottom by the beam focusing characteristics, with a certain taper, which is convenient for solder paste release, and the volume and shape of the solder paste application can be controlled;
