Solder wireIt is one of the most common types of solder in our electronics industry. During the soldering of solder wire, as the solder wire is filled with rosin, when the soldering iron is at a high temperature, the molten solder wraps around the rosin. The rosin inside rapidly vaporizes at high temperatures and breaks the wrapped solder, resulting in a cracking sound. At the same time, some shiny small tin beads of solid metal will pop out. This is the phenomenon of solder explosion. Now, let's have the Shenzhen tin wire manufacturer introduce it to you:

The main causes of tin explosion and tin burst are:

1The environment is humid, and the solder wire or circuit board gets damp. Due to the weather conditions, there is a lot of moisture in the air and the humidity is high. If the solder wire or circuit board is not properly stored, it may get damp and have moisture adhering to its surface. At this time, when we carry out soldering operations, it may cause solder explosion or solder burst.

2The tip of the soldering iron is too hot. The content and composition of flux in different solder wires are not the same. Excessively high temperatures can make the flux extremely active, thereby causing solder explosion.

3Solder wire processing issues. During the production process of solder wire, if there are cracks in the solder wire when it passes through the wire drawing machine, the drawing oil may seep into it along with the cracks, which can also cause the occurrence of solder explosion during the welding operation.

Treatment method:

1Strengthen storage measures to prevent moisture. Control temperature and humidity, and create a dry storage or working environment.

2During the production process of solder wire, strengthen inspection and control to prevent cracked solder wire from entering the wire drawing stage. If any are found, the cracked parts should be cut off for disposal.

3Strengthen the random inspection of semi-finished and finished products.

4In case of damp or continuous heavy rain, before the welding operation, please dry the plates to be welded to remove the moisture from the air on the surface of the plate pads.
