Product Description: anti copper oxidation discoloration black, protect the copper surface

I. Introduction    

1, copper is mainly used to prevent copper corrosion antioxidant discoloration oxidation, protect copper surface and any copper ions caused, and through the anion and the copper surface contact to produce an anti oxide film, so as to achieve the role of antioxidant. The antioxidant antioxidant layer of copper and copper surface generated uniformly, and the finished bare copper wire with strong appearance luster, not easy to produce pits, spots and black, and exposed a long time inventory.

2, when used in the concentration of water as long as about 0.03%, can play a role.

3, copper antioxidant and water is easy to mix, very short immersion time to achieve the purpose of protection of copper.

4, copper antioxidant on the surface of the protective layer, and will not affect the subsequent processing operations, such as solderability or brass weldability.

5, the other with a little cleaning machine, cooling tank to maintain a high level, used for quite a long time, will accumulate considerable amount of impurities, such as copper, oil and other must be within a week, the cooling bath updated to keep stable quality.

6, the subsequent drying must (must be dry.)

Two, process flow

Acid degreasing, micro etching, pre oxidation, oxidation prevention, washing and hot air drying

Three, safety and protection
