How to store lead-free tin bars?

Everyone knows that lead-free tin bar is a kind of solder material that needs to be used in soldering operations, and it is mostly used for wave soldering. The storage of lead-free tin bars is mainly for lead-free tin bar manufacturers, and some customers who use lead-free tin bars usually buy tin bars that are added to wave soldering at one time for direct production and soldering.

 

So let's understand the storage and storage problems of lead-free tin bars below:

 

1. Avoid dark and humid places. If the lead-free tin bar is placed in these places for a long time, it will affect the oxidation resistance of the tin bar.

 

2. Avoid high-temperature warehouses. Although the melting point of lead-free tin bars is above 200 degrees Celsius, the normal environment is basically no problem for lead-free tin bars; but if the temperature of the warehouse is very high, or there is a fire source nearby, it is still necessary to avoid such a place Store.

3. Don't put it next to flammable and explosive materials. If the flammable and explosive materials keep burning in the warehouse, it is also a great hazard to the lead-free tin bar.

 

4. Keep it in a clean place. The lead-free tin bar itself is very smooth, clean and bright, has good ductility, and is flat and free of impurities. Therefore, the ductility of the article is often guaranteed in the solder. However, if there is a lot of dust in the warehouse, it will eventually accumulate on the solder. In the future use, it is not only inconvenient to use, but also makes the surface of the welded article dirty.
