[ The tip before soldering ]
Apply solder to the tip end before operating.
NOTE: Applying sufficient solder makes removing easier.

The tip before soldering


Use SMD Type : Shape Quad

This shape is capable of heating IC lead wires on all 4 sides at the same time. It is used for removal of QFP.

Use it for removing QFP.
1.Apply flux to the leads.
2.Warm the IC.
3.Remove it using tweezers, etc.


Use SMD Type : Shape Tunnel

This shape is capable of heating IC lead wires on 2 sides at the same time. It is used for removal of SOP.

Use it for removing SOP.
1.Apply flux to the leads.
2.Warm the IC.
3.Remove it using a pick-up wire, etc.
