Pay attention to the welding temperature
After all, the material of aluminum substrate is different. In the case of welding, there is no doubt that we should do a good job in controlling the temperature level, so as to ensure the good welding effect and reasonably prevent certain problems.To ensure that the temperature can achieve the requirements of soldering tin, in addition, pay attention to good temperature control, do not need to be too high, otherwise that is very harmful.Welding temperature as far as possible or to ensure a very fixed, but also need to pay attention to the accuracy of the welding line, only in this way can truly ensure a very good application effect.If it is to control the temperature, of course, there will be no big problem.
Materials suitable for raw materials
Due to the whole process of welding, there is no doubt that the appropriate raw materials should be selected, so the aluminum substrate can be welded more easily.And in the case of welding, try to select some ultra-low temperature electrode and its relative welding flux, so the welding effect will be better.It is suggested that it is not necessary to apply flux of flux core type, which will lead to more difficult problems, and the welding after the event will also suffer certain harm.It is suggested that appropriate raw materials should be selected and then post welding should be carried out. In this way, the effect of solution will be better.
It is harmful to apply force to spot welding with iron head
The key to spot welding is to increase the total area of touch. It is futile to use electric iron to add force on spot welding and heating.In many cases, it can cause damage to the soldered parts, such as resistors, power switches and connectors. The welding points of the connectors are usually fixed on the plastic prefabricated components, and the results of force application are very easy to cause the original invalid.
The accuracy of solder wire must be ensured when the final aluminum substrate is made of manual solder wire.
Manual welding is a traditional welding method. Although manual welding is rarely used in the mass production of electronic equipment, it will inevitably continue to be used in the maintenance and adjustment of electronic equipment. The quality of welding also immediately endangers the maintenance effect. Manual welding is a professional skill with strong theory. After mastering the general methods, you should practice more. Practice more, and you can have good welding quality.
