Abstract
The invention provides a surface treatment process before metal electroplating. The surface treatment process before metal electroplating comprises the following steps: a. slag removal: removing impurities on the surface of a workpiece; b. spraying: carrying out spraying cleaning on the workpiece for 10-15 minutes under a spraying water pressure of 5-10MPa; c. pollution removal: treating the workpiece for 15-20 minutes by virtue of prepared pre-treatment solution; d. rinsing: transferring the workpiece, soaking the workpiece in a washing groove filled with running water, and rinsing the workpiece for 5-10 minutes; e. ultrasonic cleaning: transferring the workpiece, soaking the workpiece in a cleaning groove filled with a modified carbon cleaning agent and carrying out ultrasonic cleaning for 10-15 minutes; f. steam cleaning: carrying out vacuum n-decane steam cleaning on the workpiece for 5-10 minutes; and g. drying: carrying out vacuum drying on the workpiece at a temperature of 80-100 DEG C. The surface treatment process before metal electroplating, which is provided by the invention, is simple in procedures, convenient to operate, good in surface treatment effect, and beneficial to the subsequent electroplating procedures for the workpiece.
