[0020] Electroplating is an indispensable and important process step in the production of printed circuit boards, and electroplating uniformity is an important indicator for evaluating electroplating quality. The electroplating uniformity of existing electroplating equipment is poor. The results of its electroplating uniformity show that the copper thickness tolerance area is mainly distributed at both ends of the flybar, which is the main reason for the low overall uniformity. At present, the gantry electroplating line uses side strips on both sides of the flybar to disperse the current. The specifications of the side strips are different, which cannot effectively disperse the current and affect product quality.

It is understandable that the worker clamps the circuit board 300 to be electroplated on the bracket 100 through multiple clamps 111, and preferably the edges are flush with the hanging rod 110, ensuring that the circuit board 300 is placed vertically, and two clamps 111 are reserved at the outermost ends, and then the horizontal plates 220 of the two baffles 200 are respectively hung on the clamps 111 at the two ends. Further, the vertical plate 210 is close to the side of the circuit board 300 and abuts against the edge of the circuit board 300. It should be noted that the horizontal plates 220 of the two baffles 200 are facing each other in the back direction and are clamped on both sides of the circuit board 300. It can effectively disperse the current, reduce abnormal scrapping such as film clamping and burning, and the copper skin on the baffle 200 can be directly peeled off, the baffle 200 is recycled, and the peeled copper skin can be sold at a high price.
