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 electronic connector assembly electric plating process, which sequentially comprises the steps of electric plating pretreatment, electric plating process and an electric plating post treatment process, wherein the electric plating pretreatment comprises the process steps of deoiling, water washing, activation and water washing. The electric plating process comprises theprocess steps of nickel plating and pure tin atomization; the electric plating post treatment comprises a drying process. A steel belt has the S-shaped trend; the occupied area is greatly reduced; about 1 / 2 of the production line cost is reduced; the phosphorus content in sulfate copper plating is very low, so that the plating layer combination is tighter; a manufactured electronic device cannot easily generate desoldering; the resources can be effectively saved; the safety of personnel is protected.

Description

technical field [0001] The invention relates to an electroplating process, in particular to an electronic connector 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 ...
