Abstract

The invention relates to the technical field of welding processes, and discloses an LED circuit structural part and a welding process thereof. The welding process comprises the following steps that 1)a welder must wear anti-static gloves, anti-static wrists and anti-static work clothes, an electric soldering iron must be grounded, a workbench is an anti-static workbench, LED lamps to be welded andPCBs are flatly placed on the workbench, and bare-handed touch of two terminal pins of each LED lamp is strictly forbidden; and 2) the LED lamps are inserted into wire holes in the PCBs according tothe original circuit diagram design, and then welding is conducted one by one from left to right or from top to bottom. According to the LED circuit structural part and the welding process thereof, welding discs of the PCBs and the pins of the LED lamps are accurately preheated, so that the situation that the LED lamps are damaged or welding points do not reach the standard in the welding processis avoided; and finally through appearance inspection and repair treatment, the situation that welding does not reach the standard or products which do not reach the standard flow out is avoided, andthe effect of simple, convenient, efficient and accurate welding is achieved.

Description

technical field [0001] The invention relates to the technical field of welding technology, in particular to an LED circuit structure and its welding technology. Background technique [0002] With the acceleration of the packaging and replacement of electronic components, the original in-line type has been changed to flat-mounted type, and the connecting cables are also replaced by FPC soft boards. If there is a slight increase in welding, it will damage the components or cause poor welding. Therefore, the first-line manual welding personnel must have a certain understanding of welding principles, welding processes, welding methods, welding quality evaluation, and electronic foundation. Soldering is a science. Its principle is to heat and melt the solid solder wire with a heated soldering iron, and then make it flow into the metal to be welded with the help of flux, and form a firm and reliable solder joint after cooling. When the solder is tin-lead alloy and the soldering s...
