What are the criteria for customers to choose solder paste? When each surface mount manufacturer selects solder paste, it hopes to obtain lower solder paste to reduce production costs. However, the low price of solder paste does not necessarily meet their own production needs. So, what are the general standards for solder paste manufacturers?Today, the solder paste manufacturer is about to tell you something about this aspect. Let's take a look together.

1The solder joints are filled with tin. This is a special requirement90%According to the expectations of the guests on both sides, if the solder joints are to be filled with solder, it is necessary to select the appropriate activity and relatively good solder paste wetting performance.

2,pcbThe surface of the board shows no residue or whitening. In the face of such special requirements from customers, most manufacturers decide not to clean the solder paste. Once the problem of the board surface is caused by whitening after soldering, the post-soldering cleaning method can be chosen to solve it.

3There is no leakage of electricity or other poor electrical performance. When the customer has this requirement, do not easily choose solder paste with strong activity or high halogen content. Once the layout prerequisite can only use this kind of flux, the user can clean it to solve the problem.

4Poor conditions such as Wuxi beads, continuous soldering or virtual soldering, and missed soldering are typical undesirable situations in electronic soldering. Most manufacturers will therefore conduct relatively strict inspections and use them, fully considering the quality of the products and choosing the correct onesSMTSolder paste is the fundamental factor to avoid such adverse factors. Use solder paste with good activity and wettability, and combine it with a good manufacturing process.

The above is the customer selection we have discussed with you todaySolder pasteWhat are the standards? From this, it can be seen that such users' demands. As a domestic solder paste manufacturer, only by meeting the users' demands can it truly be recognized by customers.
