1, laser microporous technology
With the mature laser engraving technology, the micro-hole processing with a minimum diameter of 0.02mm can be realized. When the backlight is turned on, it can display a perfect laser engraving pattern, which is a new logo solution.
2, laser welding technology
Through effective control of the laser light source, OPD realizes the welding technology of aluminum and copper. The drawing force can reach more than 15N and the thrust can reach more than 30N.
