Copper plating process.
The difference between electrolytic refining of copper and copper plating is that:
Electrolytic refining of copper: crude copper often contains Fe.Zn.Ni.Ag.Au, etc., the main reaction of the anode when electrified.
The process of applying the principle of electrolysis to plating a thin layer of other metals or alloys on the surface of some metals.
Electroplating copper: CuSO4 solution anode and electrode reaction is metal copper Cu-2e- = = Cu2+ cathode and electrode reaction is plating metal Cu2++2e-=Cu.
Copper chemical element cu, is a kind of element, there is very little elemental copper in nature.
Because it is more active, it is easy to combine with other elements to form compounds.
Process flow chart of electroplating copper.
It generally includes three stages: pretreatment before electroplating, electroplating and post-plating treatment.
Complete process:
1. Full-plate electroplating with pickling.
Hardware and decorative plating process.
Hardware and decorative plating process.
Copper "pattern transfer" acid deoiling "two-stage countercurrent rinsing" micro-etching "secondary" pickling "tin plating" secondary countercurrent rinsing.
2. Countercurrent rinsing "pickling" pattern electroplating copper "secondary countercurrent rinsing" nickel plating "secondary water washing" dipping citric acid "gold plating" recovery "grade 2-3 pure water washing"
