Problems solved by technology
[0002] At present, the residual copper of the electroplated copper pin fixture is treated by nitric acid micro-etching. Nitric acid is a strong oxidizing and corrosive acid, which has great safety hazards during use. The nitrogen content of the nitric acid waste liquid is high, and the waste liquid is not easy treatment, which pollutes the environment a lot, and the nitric acid solution is easily brought into the bath solution of the post-processing process, which is easy to cause bath solution pollution, resulting in product scrapping and a reduction in the service life of the bath solution
Moreover, the traditional nitric acid nitric acid etching has high requirements on temperature and environment, and the nitric acid etching method will increase with the increase of copper ions in the tank, and the etching ability will change, which is not conducive to the removal of residual copper on the hanger.

The invention discloses a copper electroplating pin fixture residual copper treatment device. The copper electroplating pin fixture residual copper treatment device comprises a reaction pool; a pair of cathode plates is arranged on the left and right side walls of the reaction pool; a placing frame is arranged in the reaction pool; one group of conductive chucks is arranged above the placing frame; a rectifier is arranged on the external side of the reaction pool; a cathode of the rectifier is connected with the cathode plate through a lead; an anode of the rectifier is connected with the conductive chucks through leads. A copper electroplating pin fixture residual copper treatment process comprises the steps of firstly, adding a solution, which is prepared by copper sulfate and sulfuric acid, to the reaction pool and clamping the conductive chucks on the fixture with residual copper; secondly, placing the fixture in the placing frame; and thirdly, enabling the rectifier to work to perform deplating. The copper electroplating pin fixture residual copper treatment device has the advantages of convenient operation, simple process, small pollution and good residual copper removing effect.
