Solder pasteCan it be thawed repeatedly? This is essentially fine, but it is very difficult for us to achieve in the actual operation process. What's the reason? Today, the solder paste manufacturer will introduce it in detail together.
After being taken out of the refrigerator, the solder paste can be defrosted over and over again under the assumption of no oxidation. But in the actual operation process, you will see that the condition of no oxidation was not met in the first place. As long as you open the cap and use it, the solder paste may undergo an oxidation reaction with the oxygen in the air. This will very likely shorten the service life of the solder paste. Within the reasonable usage period, we must use up this bottle of solder paste as soon as possible; otherwise, it will be scrapped.
So, in practical use, we can freeze the solder paste at most twice. If the solder paste is thawed after being sealed and stored in the future, its soldering effect will be even worse, failing to meet expectations and causing greater losses.
