Selection and use of soldering iron when soldering wire
Soldering iron selection is very important for the good or bad soldering effect of the solder wire. Because the solder wire on the tin is mainly rely on the temperature of the soldering iron head to make it melt to achieve the purpose of the final welding.
1. Solder wire to have a good welding effect must choose the most suitable soldering iron head welding. According to the different design of the circuit board and different products on the temperature sensitivity of the difference, the choice of the appropriate and the iron head is particularly important. The right iron head can make the soldering wire welding to achieve twice the result with half the effort.
2. Soldering wire soldering must use a good thermal iron. Good thermal iron tip can reduce the temperature of the soldering wire welding, especially for electronic components of heat resistance considerations and the requirements of safe operation, this is particularly important.
3. Use the manufacturer's matching soldering iron tip. Iron head after a period of use will appear oxidation phenomenon, this time must replace the iron head. Emphasis is placed on the replacement of the iron head must be the same as the original configuration of the soldering iron. This can reduce the solder wire in the soldering process in a variety of failures, improve safety.
4. Soldering iron temperature must be adjusted before welding. We selected a good welding temperature according to the characteristics of the soldered product, and then adjust the temperature of the soldering iron tip, we can not be based on the soldering iron tip of the meter to determine the temperature of the tip of the soldering iron, because the meter may be damaged, producing errors. So you should test the temperature of the tip of the soldering iron with a thermometer before soldering the wire.
5. The soldering effect of the soldering wire and the soldering iron often maintenance also has a relationship. Soldering iron use for a period of time will produce oxidation, gray or black and other bad status quo, which will affect the performance of the solder wire on the tin. So we should regularly clean the soldering iron with a sponge dipped in flux to remove the oxides on the soldering iron, if necessary, should also replace the soldering iron head. There is also more than 10 minutes do not carry out soldering wire welding, should be removed from the power supply.
