Operation method and welding steps for tin plating on electric soldering iron
Regarding the knowledge of using electric soldering irons, newly purchased electric soldering irons must be evenly coated with a layer of tin on the iron head before use, which is convenient for welding and can prevent surface oxidation of the soldering iron head. Here is an introduction to the operation method and welding steps of electric soldering iron tin plating. Let's take a look together.
Prepare a piece of fine sandpaper, then gently polish the soldering iron head and heat it with electricity. Dip the soldering iron head in rosin, touch the soldering wire with the blade, melt and coat the soldering iron head to complete the tin plating operation.
If the old soldering iron head is severely oxidized or has foreign objects attached to the surface, it can be removed with steel to expose the metallic luster on the surface, and then re tinned.
Basic steps of welding
1. To ensure good conductivity of the solder joint, first polish the soldering iron head with sandpaper. Be careful not to wear the soldering iron head excessively, as excessive wear can easily lead to oxidation.
2. Heat the electric soldering iron with electricity, and when the temperature can melt the solder, apply flux to the soldering iron head, and then evenly apply the solder to the soldering iron head.
3. Use a soldering iron tip with solder to contact the solder joint. After the solder is immersed in the solder joint, slowly pull on the soldering iron.
4. After welding is completed, power off the electric soldering iron and place it on the soldering iron holder. Be careful not to be burned by residual heat.
5. The residual soldering flux on the circuit board can be cleaned with alcohol to prevent the carbonized soldering flux from affecting the normal operation of the circuit.
