Component name of the circuit board: triode, thick film resistor, plug-in terminal, heat shrinkable sleeve, sponge pad, anti-static bag

Solder paste: SnAg3.0Cu0.5 lead-free high temperature solder paste 305T800

Welding method:

1. The temperature of the soldering iron is controlled between 330 °C and 350 °C.

2: The connector cannot be welded, and the left and right are skewed and raised.

3: The tin point should be full and bright, and there should be no sharpening, less tin, bubble holes and too much tin.

4: The PCB board needs to be affixed with bubble cotton, then the sleeve is heat-shrinkable, and the air gun is used for heat shrinking.
