Samsung Electronics 2-9
2-2-3 (c) Installation
a. Clean the place where a new part will be located.
b. Apply water-soluble flux.
c. Set a part correctly in place. Prevent it from shift-
ing.
d. Stick the part fast without contacting it directly
with the soldering iron. Put 0.3mm solder between
the iron and the part so that it can melt into the
part.
e. Check the soldered part with a magnifier.

2-2-4 (a) Type
There are the following types of chip tantalum con-
denser and chip filter.
¥ Chip coil
¥ Chip tantalum condenser
¥ Chip tantalum electrolysis condenser
¥ Chip aluminum electrolysis condenser
¥ Chip transformer
¥ Chip filter
2-2-4 (b) Remoral
1. Use a special solder-removing iron.
a. Choose an iron tip that suits the size of the part.
b. Put the iron tip to the part to be soldered.
c. Remove the part when solder melts.
d. Remove the remaining solder completely with
solder-removing wire.
2. Use two irons.
a. Use an iron with small flat tip.
b. Apply heat to both ends of the part at the same
time.
c. Remove the part with the tip of the iron while
melting.
d. Remove the remaining solder completely with
solder removing wire.
