Process features
: .Water-soluble process is safe and environmentally friendly
.The process operation is simple. Just immerse the thoroughly cleaned workpiece in the working fluid to form an effective protective film on the surface of the workpiece
. This film almost does not affect the welding performance and contact resistance of the copper layer and is suitable for electronic components and circuit board copper. Protection of the protective layer
. The protective layer has no protective effect against the corrosion of water
. The protective film can withstand baking at temperatures ℃ - ℃. The protective performance will not be reduced for - hours
. The treatment area is large It can treat at least - square meters per liter. The actual maximum has reached 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: in line with EU r environmental protection standards
Process flow:
The operation of the special anti-discoloration agent for Pearl River Delta copper materials is extremely simple. 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 (note that the temperature and time are too short, which will affect the protection effect. It doesn’t matter if the protection effect is too long). Washing (very important). Washing, drying and drying (the temperature cannot be too high). Inspection and storage
