Abstract
The invention provides an electroplating solution for copperelectroplating and an electroplating process. The electroplating solution comprises the following components of 180-220g / L of main salt, 120-250g / L of amino sulfonic acid and 0.15g-0.25g / L of conductive salt, and a solvent is water. The electroplating process comprises the following steps that (1) metalcopper is put into the electroplating solution as an anode; (2) a workpiece is put into the electroplating solution as a cathode; and (3) a direct-current power supply is connected for electroplating. Inner stress of a copper electroplated layer obtained through electroplating by utilizing the electroplating solution is low, the electroplating requirements of electronic products are met, safety is achieved, and accidents are not prone to occurring.
Description
technical field [0001] The invention belongs to the technical field of electroplating solution, and in particular relates to an electroplating solution and an electroplating process for copper electroplating. Background technique [0002] With the development of industrialization, the problem of environmental pollution is becoming more and more serious. For the protection of the environment, clean, environmentally friendly and energy-saving production has attracted more and more attention from the industry. In the cyanidecopper plating process of the electroplating industry, the production process must use the cyanidecyanidecopper plating process. There are highly toxic cyanides, which pollute the environment extremely seriously and pose a serious threat to the health of workers; as people's environmental protection With the enhancement of awareness, it is urgent to develop an environmentally friendly and clean copper plating process to replace the traditional cyanide cop...
