Soldering process for soldering lamp

All solder lamps will use soldering process, which is divided into copper solder and glass solder. So what kind of standard does the soldering process need to reach to be called good? In fact, it is very simple and easy to judge the soldering process of a solder lamp. It can be started from the following aspects. First, the Tin Road is flat and smooth, and the Tin Road is relatively flat and smooth. Except for some places where tin and surfacing are needed due to structural problems, the whole tin road does not have much ups and downs. Second, there is no tin leakage. To see if tin leaks, a simple method is to see no tin leakage from the joint observed outside the all-copper lamp. Third, no light leakage. The light leakage phenomenon is mostly caused by two reasons. One is the light leakage at the joint of the glass solder lampshade due to the lack of solder; The other is because the side of the glass solder lampshade facing the ceiling can also cause light leakage because it is not in a plane. Fourth, there is no virtual welding. Virtual welding can be said to be a taboo for solder lamps. It is easy to cause the entire glass solder lampshade to fall and cause some unnecessary secondary disasters. Whether the virtual welding can be judged by the naked eye to observe whether the connection between the tin path and the lampshade is solid. It is so simple to judge the soldering process of solder lamp. Will you?
