What issues should be noted during the use of wave soldering rods?

Solder rodIt is one of the soldering products. Tin bars can be divided into lead-free tin bars and lead-free tin bars. Both are used in arc welding. At present, the design of some wave peak furnaces on the market is not ideal. The wave peaks are too high, the peak platforms are too wide, the double-wave peak furnaces are too close to each other, and rotary pumps are used. The peak is too high. When the solder drops from the peak, the temperature drop deviation is relatively large. The solder mixed with air rushes into the tin furnace, causing oxidation and semi-dissolution, resulting in the formation of solder droplet in the solder bar. The rotary pump failed to take proper preventive measures and continuously pressed the tin slag into the furnace. The chain reaction in the loop accelerated the generation of tin slag,So, what should everyone pay attention to when using it? The editor of JJY Solder Paste Factory will tell you:

1Removal of slag in wave soldering

Scum is an oxide formed on the surface of solder rods, and the rate of its formation depends on temperature and agitation. The higher the temperature and the greater the agitation on the solder surface, the more scum is formed. Antioxidants can also be added to form a protective film on the tin surface to reduce the oxidation of tin.

The oxides on the surface of the solder rod can prevent the solder from reoxidizing, so it is not necessary to remove the scum frequently. As long as it doesn't affect the push of the waves, it's fine to clean it once a day. You can also push the tin slag to a corner, add reducing powder to the tin slag and stir it again, which can reduce most of the tin slag to tin.

2The addition of new solder bars in wave soldering

During the wave soldering process, the amount of tin will continuously decrease. When it drops to a certain level, new tin bars should be added in time. To maintain the liquid level of tin and reduce the oxidation of tin caused by the large drop of tin waves.

3ImpuritiesCuThe removal (leaded and lead-free tin bars), and regular detection of the composition of solder in the tin furnace (lead-free tin bars)

The most appropriate time to add the solder strip is to always keep the distance between the solder surface and the peak as short as possible. Have you frequently cleaned up the solder dross so that the solder falling from the peak can enter the furnace as soon as possible instead of remaining on the solder dross? Uneven heating can also cause excessive solder dross. Regular furnace cleaning is also very crucial. If the furnace is not cleaned for a long time, the impurity content in the furnace will be relatively high, which is also one of the reasons for excessive tin slag.
