How do you solder aluminum PCB?
In the production process of offering aluminum PCB fabrication services, in order to ensure a better application effect, hand-soldering tin wires are usually used afterwards. Then, what issues should be paid attention to for manual soldering wire of PCB metal base printed board?
1. Pay attention to the welding temperature
Due to the particularity of the metal base printed board material, in order to ensure the PCBA welding effect, it is necessary to ensure the operation of the temperature level during welding, the welding temperature should be kept as constant as possible, and the welding accuracy should be paid attention to. Only in this way can a very good application effect be guaranteed.
Second, select suitable raw materials
In the metal base printed board welding process, it is particularly important to select suitable raw materials. Try to choose some ultra-low temperature welding rods and their relative flux, so that the welding effect will be better.
Third, it is harmful to apply force to spot welding with a soldering iron tip
The soldering iron tip transfers the heat to the PCB spot welding. The key is to increase the total contact area. Applying force to the spot welding with an electric soldering iron has no effect on heating. In many cases, it can cause damage to the welded parts. Welding points such as resistors, power switches, and connectors are generally fixed on plastic prefabricated components, and the result of force is likely to cause the components to become invalid.
Summary: Although manual welding is rarely used in the manufacture of large quantities of electronic equipment, manual welding is still inevitable for the maintenance and adjustment of electronic equipment. At the same time, manual welding is a theoretical professional skill, and the quality of welding will also impair the maintenance effect.
