If the nozzle tip is coated with
oxidized film or the like, its thermal
conductivity deteriorates. In contrast,
if the nozzle end is wetted with a
small amount of clean solder, its
thermal conductivity increases.
1. Melt the solder.
Position the nozzle above the
lead to be desoldered as shown
in the illustration and melt the
solder.
CAUTION
Never allow the nozzle to touch the
board itself.
Confirm that the solder is melted.
CAUTION
To confirm that all solder is melted,
observe the inside of the hole and
the backside of the P.W.B. If this
is difficult to do, try slowly moving
the lead with the nozzle. If the lead
moves, the solder is melted. Never
move the lead by force. If it doesn’t
move easily, the solder isn’t yet fully
melted.
2. Extract the solder.
After confirming that the solder
is completely melted, extract the
solder by pressing the button (or
squeezing the trigger)
CAUTION
Never leave any solder remaining
inside the hole in the P.W.B.
3. Problems during
desoldering.
If solder remains, resolder the
