First of all, you need to connect the fire line and the neutral line to the power side of the electric iron to ensure that the electric iron gets the working power.
Then, insert the IC integrated circuit into the weld base, making sure that the corresponding position of the pins and the weld base is correct.
Next, the pin to be welded is heated with a soldering iron, and the solder is applied to the contact point between the pin and the weld base.
Finally, wait for the welding to be completed, unplug the soldering iron, and let the IC IC cool and finalize. It should be noted that during the welding process, attention should be paid to controlling the temperature and welding time of the soldering iron to avoid damaging the IC integrated circuit.
No grounding wire can also be welded, direct welding line, charged will not break down the integrated circuit (as long as the integrated block itself is not energized).
The grounding of the soldering iron shell is mainly to prevent the induction of static electricity on the integrated block, and it is best to connect the grounding wire to the soldering iron shell for the computer integrated block with high integration.
