What causes tin cracking in solder wire during production? How to solve it?

Nowadays, many manufacturers are placing ordersSolder wireWhen it comes to this, people usually ask why the phenomenon of tin explosion occurs during soldering, what causes this situation and how to avoid it. In fact, "tin explosion" It is a common phenomenon during solder wire soldering operations. Mainly, when the high-temperature soldering iron tip touches the solder wire during the soldering operation, some conditions may occur. Now, JJY solder Paste Manufacturer will lead you to understand some of the reasons:

Sometimes, there is the issue of moisture absorption: Due to the presence of moisture in the air, especially during the spring rainy season, particularly in the humid weather of Guangdong, solder wires (solder wires) or circuit boards may become damp and retain moisture on their surfaces due to improper or inadequate storage, which can cause intermittent solder cracking or explosion.
Problems in tin wire processing: During the production of solder wire, if there are cracks in the solder wire (tin wire) when passing through the wire drawing machine, the drawing oil will seep in through the cracks, which can also cause the occurrence of tin explosion during the soldering operation.

How to solve:

1When producing solder wire, the content of flux should be appropriately reduced to lower the moisture content inside. However, this approach is based on the premise that after reducing the amount of flux, there can still be good solderability, firmness and other soldering effects, because the quality of the solder wire is ultimately reflected in the soldering effect. 

2Strengthen storage measures to prevent moisture, control temperature and humidity, and maintain a dry storage or working environment. 

3During 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.

As mentioned above, everyone still needs to be more careful and attentive during the operation process to prevent unnecessary situations from recurring. If you still have any questions or want to learn more about soldering, please feel free to call for consultation!!
