Abstract

The invention provides a detection method of bonding force between nickel aminosulfonate plating solution clad layers, and a method for reliability detection of the bonding force between the plating layers generating abnormal conditions to control the plating liquid through detection of the bonding force of the plating liquid to avoid the problem of the bonding force of the plating liquid. The electroplating substrate is firstly degreased, washed with water, then pickled and washed; the treated electroplated substrate after processing is placed on the plating solution for the first detection;the electroplated substrate is continuously placed on the plating solution for electroplating to perform secondary detection to add three electroplating detection as required and determine the bondingforce between the plating liquid. The detection method provided by the invention is a scheme that eliminate the plating liquid problem through detection of the bonding force of the plating liquid tohelp the production with rapid search of a production line, determines whether the bonding force of the plating liquid has problems or not through the lab electroplating test to further determine thesource causing the poor bonding force problem so as to achieve the purposes of reducing unnecessary material resource and man resource loss and improving the working efficiency.

Description

technical field [0001] The invention relates to a method for detecting a coating of a nickel sulfamate plating solution, in particular to a method for reliably detecting the binding force between coatings of a nickel sulfamate solution. Background technique [0002] There is an interaction force between particles in the crystal, which is called "binding force". Electroplating is to form a conductive metal layer on the surface of the electroplating substrate through chemical electroplating, and electroplating will be superimposed between the metal plating layers. No matter which step has poor bonding force, the electroplating work cannot continue. There are many reasons that affect the poor bonding force between the coatings, such as pretreatment problems, excessive pickling, a large amount of metal impurities in the plating solution or too much organic matter. Electroplated products will eventually lead to unqualified products or reduced performance due to poor bonding forc...
