Double-wave soldering machine
PCB panel through double wave soldering machine, there is some strength, such up or down. Ensure the LED panel solder very well, then we can reduce the rate of rosin joint.
Process Control --4

unleaded solder paste unleaded solder paste
keep the unleaded solder paste in the ice box
When use paste, it need to thaw for 3 or 4 hours
Mixing solder paste for 5—10 minute
Putting the solder paste to steel mesh surface, then draw to the PCB surface
