Poor soldering of electronic products with
tin bars can cause problems with circuit boards. Let's introduce tin bar + flux to ensure excellent solder joints.
Perfect solder joints: use the right flux, there are many types of flux, there are lead-free flux and lead flux, which one you use when soldering is very important, choose the right flux for the excellent quality of solder joints Role is crucial.
The use of solder bar: First of all, you need to know the melting temperature of the solder bar, but the actual working temperature is 20 degrees higher than its melting temperature. At this time, the dispersibility of the solder bar is the best. It is best to use a solder bar with strong oxidation resistance because it produces relatively less tin slag, which is of great help to the welding of solder joints and reduces the occurrence of waste products.
Selecting the right flux and suitable solder bar is a strong guarantee for the solder joints, and the perfect solder joints can be welded only by the close cooperation between the solder bar and the flux.
