<Care of Iron Tip>
1) Check iron tip by eyes every fixed time
Oxide is left on the iron tip. Study of the number of air blow cleaning.
“Solder rise” exceed the solder plated area. A malfuction is occurred by leavening a
corrosion by chloride element in flux.
Replace the iron tip.
Bad solder flow Remove pre-soldering on the iron tip
completely. Cool it to room temperature and
remove oxidation by a sand paper. Then turn
it on again and make pre-soldering to the iron
tip surface during rising temperature.
Transformation of iron tip Need to change of iron tip by the corrosion of
chloride
element in flux and wear
phoenomenon.
2) Check for soldering defect
Imperfection of electric connection by of flux
membrane. Clean the surface and make iron tip
temperature high and heating longer.
Rough soidering surface This defect occurs if the heating temperature is
high or low. Adjust it to proper temperature.
Soldering removes and comes off because the
solder does not melt. Shortage of heat
Solder flow A malfuction is occurs if the heating
temperature is high, the heating time is long or
the exceeding solder feed amount is supplied.
There are many solder defects except the above mentioned as follows:
“Solder shortage”, “Icicle”, “Solder excess”, “Burning film” etc.
Please select suitable condition by seeing through the solder states.
