What problems can be avoided by standard operation of electric soldering iron
1. High temperature soldering can damage some electronic components, including plastic connectors, relays, LEDs, electrolytic capacitors and multilayer ceramic capacitors.
2. High temperature will bend the circuit board, resulting in damage to multilayer ceramic capacitors (common damage)
3. High temperature soldering will cause thermal shock to components
4. High temperature will dissolve or deform plastic components
5. High temperature soldering will accelerate oxidation and affect the diffusion and wettability of solder
6. It is necessary to use highly active (strongly corrosive) flux
7. To provide more heat and welding for a longer time to achieve the ideal welding effect
8. It is easy to produce tin bridge and false soldering, and it is not easy to correct
9. It is easy to produce solder balls and flux flying
10. Shorten tip life
11. The color of the solder joints will be darker
12. The operator will feel uncomfortable and worry about whether to change the welding mode
