Product introduction: The anti-discoloration agent for copper materials after electroplating is a special protective agent for copper and copper alloys and is a water-soluble process. It is a nanotechnology product. This protective agent forms a colorless and transparent film on the surface of copper and copper alloys, with a film thickness of several nanometers. It can prevent water, seawater, atmosphere, oxygen, hydrogen sulfide, sulfur dioxide, and some organic vapors from corroding the workpiece. Mainly used for the protection of copper and copper alloys in indoor environments.
Process features:
. Water-soluble process, safe and environmentally friendly
. Simple process operation. Just immerse the thoroughly cleaned workpiece in the working fluid to form an effective protective film on the surface of the workpiece
3. This film hardly affects the welding performance and contact resistance of the copper layer, and is suitable for electronic components and Protection of the copper layer of the circuit board
. The protective layer has no protective effect against the corrosion of ammonia or ammonia
. The protective film can withstand baking at temperatures of ℃-℃ for several hours without any reduction in protective performance
.The treatment area is large, and it can treat at least - square meters per liter, and the actual maximum has reached 3 square meters/liter
. Compared with other systems containing formic acid, the acetic acid system has better stability and is less corrosive.
.Environmental protection index of this product: complies with EU R environmental protection standard
Process flow:
Renchang copper passivator is extremely easy to operate, just dilute the concentrated solution in pure water and it can be used. The process is: copper plating, washing, washing and dipping in protective agent (pay attention to temperature and time, too short time will affect the protection effect, too long is okay), water washing (very important), water washing, spin drying (temperature should not be too high), inspection and storage
