Why does lead-free solder wire splash rosin

The phenomenon of rosin splashing often occurs during soldering of lead-free solder wire. Welding personnel generally call it "explosed tin" or "fried rosin. When encountering this situation during lead-free soldering, employees' productivity will be affected. How to prevent this from happening? Xinghongtai tin engineers will discuss with you:

1. The temperature is too high when soldering lead-free solder wire.

The melting point of lead-free solder wire is generally about 227 degrees, so the temperature of the soldering iron is generally adjusted to 280 degrees -300 degrees. If the temperature of your soldering iron is higher than 300 degrees, then the undesired phenomenon of lead-free solder wire splashing rosin will appear. At this time, you should readjust the temperature and control the soldering temperature.

2. The product quality of lead-free solder wire has a great impact.

If the quality of the lead-free solder wire is not good, if it is made of rosin flux containing moisture and recovered tin, then the phenomenon of rosin splashing or tin explosion will occur. If the occurrence of blasting tin or splashing rosin is too frequent, then you need to consider changing suppliers, indicating that the quality of their lead-free solder wire is not good.

3. Whether the soldering iron tip is oxidized will also affect the soldering of lead-free solder wire.

After a long soldering time, the soldering iron head will become oxidized and gray or black. Such a soldering iron head is useless and needs to be replaced. Therefore, for the soldering of lead-free solder wire, always check the use of the tip and replace it if necessary.

4. Lead-free solder wire should be placed in a cool and ventilated place.

If the lead-free solder wire is placed in a dark or wet place, the lead-free solder wire is prone to moisture if it is left for a long time. If the lead-free solder wire is wet, there will be a phenomenon of splashing rosin or exploding tin. . Therefore, Xinghongtai tin industry engineers suggest that lead-free solder wire should be placed in a cool and ventilated place. Also, lead-free solder wire cannot be left for too long. Generally, it is safer to use it out within 3 months. Therefore, lead-free solder wires can be purchased in bulk at one time.

5. The welding process level of employees is also related.

When soldering lead-free solder wire, employees generally need to be trained in advance before they can operate the electric iron. The most important thing when soldering lead-free solder wire is to master the speed of pushing or pulling the wire. If it is pushed too fast or pulled too hard, it will also cause tin explosion or splashing.
