Second, put the PCB into the LED soldering machine and the LEDs will be automatically soldered onto the surface of the PCB by the machine.
Third, let the PCB pass through the reflow soldering machine to make LEDs fixed on the PCB.
Fourth, put the PINs into the holes of the PCB by hand.
Fifth, press the heads of the PINs with the pressing machine and solder them with TIN.
Sixth, quality test. Check if there is any fault.
