pretty! RFH 355nm UV laser cutting copper foil multi -line   Which do you think is more difficult to process precision materials and large machinery?   Looking at the copper foil with only micron (UM) thickness in your hand, RFH is easily completed through ultraviolet laser, cutting off the high accuracy, smooth edges and no burrs, and no signs of carbonization. It is perfect! Materials such as copper foil are absolute necessities in the field of PCB and battery, and they are also one of the most important electrolytic materials.
