Solder paste is generally classified into the following categories:

1No-cleaning solder paste. This type of solder paste has a smoother soldering surface with less residue and can be processed through various techniques There is no need for further cleaning. While ensuring the welding quality, it shortens the production process and speeds up the production progress;This kind of solder paste is the most widely used and has a wide range of applications.

2Ordinary rosin cleaning type, this solder paste shows a good "soldering speed" during the soldering process and can ensure a good "soldering effect". After the soldering work,PCBThere is a considerable amount of rosin residue on the surface, which can be cleaned with an appropriate cleaning agent to ensure that the cleaned surface has good insulation resistance and can be tested through various functions.

3Water-soluble solder paste, due to technical reasonsPCBThe residue on the surface of the board was generally too large, the electrical performance was not ideal, which seriously affected the product quality and was used at that timeCFCThe cleaning agent is used for cleaning becauseCFCIt is not conducive to environmental protection and is banned in many countriesCFCTo meet the demands of the market, water-soluble solder paste was produced. After the soldering work with this solder paste is completed, it can be washed with water, which not only reduces the production cost for customers but also meets environmental protection requirements.
