CNSMT WAVE SOLDERING MACHINE
Application
crafting process
After the board enters the wave soldering machine through the conveyor belt, it passes through some form of flux coating device where the flux is applied to the board by means of crests, foaming or spraying. Since most fluxes must reach and maintain an activation temperature during soldering to ensure full solder joint penetration, the board must pass through a preheat zone before entering the crest. Preheating after flux application can gradually raise the temperature of the PCB and activate the flux. This process also reduces the thermal shock that occurs when the assembly enters the peak. It can also be used to evaporate all possible absorption of moisture or carrier solvents that dilute the flux. If these things are not removed, they will boil over the peak and cause solder sputter, or steam will remain inside the solder to form a hollow. Solder joints or trachoma.
