component off with suitable tools on the component side.
b. Remove solder from mounting holes with suction desoldering aid or wooden toothpick.
REPLACEMENT
a. Cut leads of replacement component to allow 1/4 inch more than finished length. Shape leads to conform
with holes in card.
b. Insert component leads into mounting holes. Position component in the same manner as the original.
c.
Solder leads to bottom of printed conductor side of card, making sure component maintains proper position.
d. Clip the excess component leads to within 1/32 inch from soldered surface.
NOTE
When replacing axial lead components such as tubular capacitors &
resistors, it is not necessary to unsolder the faulty component. You may
clip the leads close to the body of the faulty component, remove the
component, and straighten the lead end still soldered to the card.
Introduce the new component by placing it properly, then wrap the leads
of the replacement once around the original lead stub.
Solder the connection and clip excess lead.
