Precautions and temperature setting methods for using a soldering iron
2020-10-19
The SOLDERING IRON is the primary tool for soldering components and wires. Before use, several factors require attention, including temperature setting. Let's explore the precautions and temperature setting methods for using a SOLDERING IRON.
Precautions for Use:
1. The SOLDERING IRON should have a ground wire;
2. Before using the SOLDERING IRON, check that the operating voltage matches the rated voltage of the SOLDERING IRON;
3. The SOLDERING IRON should be kept dry and should not be used in excessively humid or rainy environments;
4. After powering on the SOLDERING IRON, do not arbitrarily strike, disassemble, or install its heating element parts;
5. When removing the soldering iron tip, disconnect the power;
6. After disconnecting the power, it is best to use the residual heat to apply a layer of solder to the soldering iron tip to protect it;
7. When there is a black oxide layer on the soldering iron tip, use sandpaper to remove it, then power on, and immediately apply solder;
8. The sponge is used to collect solder residue and solder beads; it should be squeezed just enough so that no water comes out;
9. Perform "5S" before and after soldering.
Temperature Setting:
1. For general through-hole electronic components, set the actual temperature of the soldering iron tip to (330-370 degrees); for surface mount components (SMCs), set the actual temperature of the soldering iron tip to (300-320 degrees).
2. The temperature is determined by actual use; it is most suitable to weld a solder point in 4 seconds. Observe the soldering iron tip; if it turns purple, the temperature is set too high.
3. For microphones and buzzers, use silver-containing solder wire, with a temperature generally between 270 and 290 degrees.
4. When soldering large component leads, do not exceed 380 degrees; only increase the soldering iron power.
5. Special materials require special soldering iron temperature settings.
Using a SOLDERING IRON requires great care and attention. Improper operation can not only affect the soldering effect but also cause harm. Therefore, mastering the basic operating requirements is a prerequisite for safe work.
