Solder paste manufacturer explains that, during use, Solder paste may change in viscosity and suffer from problems such as drying out. For example, poor print quality, insufficient deposition and low tin content will all reduce the yield during soldering.

There are many reasons for these problems. From a chemical-reaction standpoint, new substances form between the Solder Flux and the tin powder. JJY Solder Paste Manufacturer now tells our partners how to avoid Solder Paste drying out too easily:

Perhaps many partners have faced this: if Solder paste has been used for too long or stored for a long time, it feels a pity to throw it away. JJY Solder Paste Manufacturer reminds partners that the Flux contains active agents and plays a key auxiliary role in soldering.

At room temperature, the chemical properties of the flux are relatively stable. Flux is added to remove surface oxides from the workpieces to be soldered and to improve their wettability; its main function is to alter the functional-group structure.

Under any conditions, a chemical reaction always takes place between the solder flux and the tin powder. Since the reaction rate is affected by temperature, the lower the temperature, the slower the reaction. It follows that storing solder paste at low temperature preserves it better and extends its service life. At room temperature, the service life of solder paste depends on the speed of the reaction between the flux and the solder powder.
