Causes of solder explosion on soldering machine PCB
PCB board inspection
The inspection of the PCB is relatively simple. It is required that the surface of the PCB be dry and free of moisture. Some factories do not store the PCB well, and it is easy to cause the PCB to be wet. At this time, the solder explosion will occur when the solder is properly connected to the tin.
Inspection of flux
Manufacturers of machines and equipment that use automatic soldering machines use solder wire for the flux. The phenomenon of tin explosion occurs mainly because the moisture in the air will affect the flux. To avoid this phenomenon, If it happens, the operator should check and replace the air filter at any time. Customers using liquid fluxes should pay attention to the composition of the solution. Some manufacturers use methanol to replace isopropyl alcohol or anhydrous ethanol in order to reduce production costs. Methanol itself contains a small amount of water, which often occurs during soldering. The phenomenon of tin explosion.
What is the reason for the tin explosion phenomenon in the soldering PCB version? The above is the introduction of the relevant content. The humidity environment is monitored. Generally, the occurrence of tin explosion can be solved. http://hfkjbxg.icu/
