Embodiment 1
[0022] Embodiment 1: an LED circuit structure and its welding process, comprising the following steps:
[0023] 1) Welding personnel must wear anti-static gloves, anti-static wrists and anti-static overalls. The electric soldering iron must be grounded. The workbench is an anti-static workbench. Place the LED lamp and PCB board to be welded flat on the workbench. It is strictly forbidden to touch the LED with bare hands. The two lead pins of the lamp;
[0024] 2) Insert the LED light into the wire hole in the PCB board according to the original circuit diagram design, and then solder one by one from left to right or from top to bottom. The glue of the LED light and the PCB board should keep a distance of more than 2mm. The soldering temperature is 260°C to 300°C, and the soldering time is 1 to 4 seconds. During the soldering process, the angle between the soldering iron tip of the electric soldering iron and the PCB board is 30 degrees. pins of the lamp and heat it evenly;
