What preparations need to be made before lead-free solder paste is printed?

Lead-free solder pasteIt is an indispensable material in the electronic soldering industry. It can firmly connect electronic components to printed circuit boards, forming stable and reliable electronic products. But, do you know? There are some preparatory works that must be done before lead-free solder paste printing; otherwise, it will affect the printing and soldering effect, and even cause faults or damage to electronic products. So, what are the matters that need attention? Now, Shenzhen JJY Solder Paste Manufacturer will explain it to you:

1After taking the solder paste out of the refrigerator, pay attention to the expiration date of the solder paste. If it has expired, it cannot be used and should be scrapped. When taking solder paste, the principle of "first in, first out" should be followed. If there is any solder paste that has been opened before but not used up, it should be used first.

2After lead-free solder paste is taken out of the refrigerator, it must be warmed up at room temperature4For more than an hour, avoid the generation of moisture.

3The lead-free solder paste that has been warmed up well should be stirred in a centrifuge1~2Minutes, or open the lid and stir by hand. The manual stirring time is3Do not open the lid before stirring for about minutes.

4All operations and solder paste specifications, etc. must be well recorded for future verification.

These are the four points to note before lead-free solder paste printing. They are: checking the expiration date and usage sequence of the solder paste, warming the solder paste to avoid moisture generation, stirring the solder paste to make it flow evenly, and recording the operation and specifications of the solder paste, etc. After completing these tasks, lead-free solder paste can be smoothly put into production and use. Of course, to achieve better soldering results, there are still other preparatory works to be done, such as cleaning the solder paste printer and designing the steel mesh.
