Soldering
Inaduertant soldering
of
delicate component can cause
component
damage. Carefully read and
fllow
the reccauting in Section 6.2.1
for
component removal and soldering
to
safeguard the Maple
computer's circuitry.
6.3.1
Removing
and
Installing
Parts
(1) When removing parts such
as
IC's, transistors, etc. from the board, cut the lead wires
of
the
parts
with
nippers and remove
the
solder.
Melt
the solder rapidly
to
prevent the parts from ab-
sorbing the heat.
(2) Solder each part quickly and use cooling agents
to
cool the part (to
protect
the parts and print-
ed circuit board).
(3) When removing parts, remove the solder from the holes using SOLDER REMOVER; pull
out
the lead wires,
which
were cut
in
advance. This should
be
done
without
excessive use
of
force
in
order
to
protect
the land and
print
pattern from being removed.
