PCB is an indispensable product in the electronics industry. It has a wide range of uses, increasing usage, and product quality requirements. improve. The labor cost has gradually increased. Need to achieve high capacity, to increase speed, improve yield, reduce costs, optimize products, only to replace the machine.

After the plated copper plate comes out of the copper-plated area, it must be acid-washed, washed, anti-oxidized, micro-etched, blow-dried, dried and other post-treatment equipment. Previously, the board was manually taken, if the thickness of the production board was 0.036. When the ultra-thin plate of mm~0.1mm is used, the plate is scratched and deformed, and the quality is not met. If the copper plate after the completion of copper plating can be automatically transported into the post-processing equipment without human intervention, this will not only greatly improve the efficiency and quality of the company's production, but also enhance the company's competitiveness in the market.
