Problems solved by technology

[0002] In the original continuous copper plating of steel strips, multiple copper plating tanks, auxiliary tanks and other auxiliary equipment are required. The continuous copper plating production line of steel strips is 80 meters long and occupies a large area. The steel strip production line is about 20,000 yuan per meter , the one-time investment is too large, the overall production efficiency is low, and a large number of staff are required for maintenance operations, resulting in a waste of financial and material resources

Abstract

The invention discloses an electroplating technology. The electroplating technology sequentially comprises the steps of pretreatment before electroplating, the electroplating process and electroplating post-treatment, wherein pretreatment comprises the steps of oil removal, water washing, activation and water washing; the electroplating process comprises the steps of palladium and nickel plating,nickel plating, gold plating and pure matte tin; electroplating post-treatment comprises a drying process. A steel strip is in an shape, so that the occupied area is greatly saved, and the cost of a production line is reduced by about one half; the content of phosphorus in sulfate copper plating is extremely small, so that the bonding of a coating is tighter; an manufactured electronic device is not easy to deweld; resources can be effectively saved; the safety of personnel is protected.

Description

technical field [0001] The invention relates to an electroplating process. Background technique [0002] In the original continuous copper plating of steel strips, multiple copper plating tanks, auxiliary tanks and other auxiliary equipment are required. The continuous copper plating production line of steel strips is 80 meters long and occupies a large area. The steel strip production line is about 20,000 yuan per meter , The one-time investment is too large, the overall production efficiency is low, and a large number of staff are required for maintenance operations, resulting in a waste of financial and material resources. In the original continuous copper plating of steel strips, only one or two steel strips can be electroplated at a time. In the content of the present invention, the steel strips are in an S-shaped direction in the pre-treatment tank and the plating tank, which greatly reduces the occupied area and saves the production line. The cost is about one-half, ...
