5.
Crimp or bend the lead (or leads) around the
terminal to form a good joint without rely-
ing on solder for physical strength, unless
otherwise instructed in the STEP- BY -STEP
ASSEMBLY. If the wire is too large to allow
bending or if the step states that the wire
is not to be crimped, position the wire so
that a good solder connection can still be
made.
6.
Position the work, if possible, so that gravity
will help to keep the solder where you want
it.
7. Place a flat side of the soldering iron tip
against the joint to be soldered until it is
heated sufficiently to melt the solder.

8. Then place the solder against the heated
terminal and it will immediately flow over
the joint; use only enough solder to thor-
oughly wet the junction. It is usually not
necessary to fill the entire hole in the
terminal with solder.
9. Remove the solder and then the iron from
the completed junction. Use care not to move
the leads until the solder is solidified.
A poor or cold solder joint will usually look
crystalline and have a grainy texture, or the
solder will stand up in a blob and will not have
adhered to the joint. Such joints should be re-
heated until the solder flows smoothly over the
entire junction. In some cases, it may be neces-
sary to add a little more solder to achieve a
smooth bright appearance.
