Sharing methods for improving the welding quality of electric soldering irons
1. When using an electric soldering iron for welding, it is necessary to ensure that each welding point is firmly welded and in good contact to ensure welding quality.
2. Good solder joints require bright, smooth, and free from burrs, with a moderate amount of tin. Tin and the solder are firmly fused. There should be no false soldering or false soldering.
3. Pay attention to preventing the problem of false soldering and false soldering: False soldering refers to only a small amount of solder stuck at the solder joint, resulting in poor contact and intermittent disconnection. False soldering refers to a situation where it appears to be soldered on the surface, but in reality it is not soldered on. Sometimes, with a single hand pull, the lead will be pulled out of the solder joint.
Only through extensive and careful welding practice can these two major problems be avoided.
4. When welding circuit boards, it is necessary to control the time. If the time is too long, the circuit board will be burnt or the copper foil will fall off. When disassembling components from the circuit board, the electric soldering iron tip can be attached to the solder joint, and after the tin on the solder joint melts, the component can be pulled out.
5. Fluxes (rosin and soldering oil) are crucial during welding. Fresh rosin and non corrosive soldering oil help to achieve high-quality welding and make the surface smooth and beautiful. Use a versatile flux.
Reasons for electric soldering iron leakage
The main reason for the leakage of soldering iron is caused by the leakage of the soldering iron core.
The soldering iron core is composed of an electric heating wire, an insulation layer support, and an insulation layer. When the insulation layer is damp or aged for too long, the insulation level may decrease, leading to leakage of the soldering iron core. Then, it flows out through the heat transfer shell of the electric soldering iron and the soldering iron head.
The handle of an electric soldering iron may also experience leakage faults after excessive aging and specialization.
After the electric soldering iron leaks electricity, the problem is very serious and can easily cause electric shock accidents. It poses great harm to people and electronic and electrical equipment to be repaired. Please immediately replace the soldering iron core and leakage components, and if necessary, replace them as a whole.
