UsedSolder pasteSuch people might have such an experience:Why is there such a big difference in quality among solder paste products of the same specification? High-quality solder paste can be printed in one go, while counterfeit and shoddy solder paste always have various problems. The solder paste manufacturer will take everyone to explore the explanations within this:

1The solder paste formulas are different

The production methods and formulas of solder paste vary among different solder paste manufacturers. Solder paste produced with a good formula has better stability performance and superior product quality. Poor formula leads to poor quality stability of solder paste products.

2The quality of tin powder products is different

High-quality solder paste is made from superior solder powder and has excellent climbing and solderability. Poor-quality solder paste, on the other hand, is made from regenerated tin powder, which has been oxidized to some extent and has relatively poor solderability.

3The manufacturing processes are different

High-quality solder paste is usually produced in a dust-free and constant-temperature workshop by a vacuum mixer, with uniform color of the solder paste. The production process of counterfeit and substandard solder paste is not guaranteed. It is made by hand and stirred, and oxidation may occur during the production process.

4Incorrect operation

No matter which solder paste is not properly stored, it will produce oxidized tin, resulting in poor soldering effect. In addition, the operational skills during the printing process are also the key to solder paste soldering.
