WARNING: ISOPROPYL
ALCOHOL IS TOXIC AND
FLAMMABLE. DO
NOT BREATHE VAPORS. USE IN WELL VENTILATED
AREA FREE
FROM SPARKS, FLAME
OR HOT SURFACES.
WEAR
SPLASH
GOGGLES,
SOLVENT
RESISTANT
GLOVES, AND OTHER
PROTECTIVE GEAR.
IN CASE OF
EYE CONTACT,
FLUSH WITH WATER
AND SEEK MEDICAL
ATTENTION.
IN CASE
OF SKIN CONTACT,
WASH
WITH
SOAP AND WATER.
3. Soldering
A.
Strip sufficient
insulation from
the wire or component
leads
so that no insulation
will touch
the solder
connection.
Insulation
clearance is the gap
between the insulation
and the edge of the
terminal or
solder
cup. Refer to Figure 207. Refer
to Table 201 for insulation clearance.

B.
Surfaces to
be joined by soldering
must be
free of dust,
oil and oxides.
Clean surfaces
with solvent or
wire brush, do not use steel wool.
C. Pretin wires
and leads before
joining by soldering.
Part leads or terminals
pretinned by the
manufacturer
do not
require tinning
unless corrosion
has occurred
during
storage. Corrosion
must
be removed and the
part pretinned before
soldering.
D. When
required, shrink
tubing or
other insulating
sleeving should
be installed
on wires prior
to
attachment to terminal.
Refer to Figure
205.
E. Hold
the parts to be soldered
together in a position
to assure proper
fit during the soldering
operation.
(1) Wires and component
leads should be wrapped around a turret
terminal or solder hook, or held,
in
a manner that will prevent
the wire from
moving while the solder
is cooling. Movement
of the
wire during
cooling will result in
a cold solder joint.
(2)
The wrap of a conductor
around a turret
terminal should not
be less than 90 degrees
or more
than 270 degrees.
Refer to
Figure 201
F.
The soldering
iron tip should
be clean, smooth
and brightly
tinned. A cellulose
sponge
moistened with
water
provides a good pad
for cleaning the tip.
(1) The soldering
iron should be a size
that will heat the joint
rapidly, but will not
damage adjacent
areas.
(2)
The soldering iron tip should be grounded
when soldering voltage sensitive components.
