High Power UV Laser Marking in the Semiconductor Industry
Copper foil is a negative electrolytic material, a thin, continuous layer of metal foil deposited on the base layer of the circuit board, which acts as the conductor of the PCB. It easily adheres to the insulating layer, accepts the printed protective layer, and forms a circuit pattern after etching. Due to the small thickness of the copper foil, it is easy to lose balance or affect the accuracy due to relatively high impact or material, but the RFH 10w UV laser can solve this problem.
