Solder paste manufacturers will tell you: What are the benefits of storing solder paste?

Solder paste is a new type of soldering material, composed of solder powder, fluxes and other surfactants, thixotropic agents, etc. Many people are wondering what effects will occur after reflow soldering if it is not used in the conventional way. Solder paste is a relatively expensive and difficult-to-store soldering product among tin-based soldering materials. Improper storage is very likely to cause various adverse phenomena during the use of solder paste. JJYSolder paste manufacturerNow let me tell you all about the benefits of storing solder paste?

Storage method of solder paste:

I. Storage of Solder Paste: As solder paste is a chemical product, it must be stored in5-8The cold storage with a certain degree of temperature, the advantage of doing so is to reduce the activity of the chemical flux in the solder paste and extend the service life of the solder paste. The solder paste should not be placed in a high-temperature area, as it will cause a qualitative change in the solder paste.

2. Solder paste warming: The activity of solder paste is greatly reduced when it is refrigerated, so it should be used in advance2-4Leave the solder paste at room temperature for an hour to restore its activity and bring it to the best soldering state.

Iii. Solder paste Stirring:

1Stirring is to ensure that the tin powder in the solder paste is evenly mixed with the flux. However, if the stirring time is too long, it will damage the shape of the tin powder and even its viscosity. The general stirring time is approximately2About a minute.

2If hard lumps form on the surface of the solder paste before stirring, remove the surface lumps before use.
