| The next step is to tin the RCA jack center terminal with
solder. This helps the soldering process of the wire to be quick,
minimizing the heat to the center wire. In this picture you can see the
black insulation around the center terminal. Although this black
insulation shoulder isn't exposed much, the objective is to cover this
center connection with heat shrink tubing as best possible to insulate the
center wire from ground after the wire is soldered on.
Proper insulation around the center terminal will prevent shorts. |
 |
| You're ready to solder the RCA jack onto the center wire.
Put a .5" long piece of .25" diameter heat shrink tubing around the center
wire. Quickly solder the wire to the center post of the RCA
jack. Remember, do not solder the ground wire, that will need to be
bare strands of wire to pinch in the base. |
 |
| This is what the solder joint should look like. Make
sure you let the soldering iron heat up fully before soldering the wire to
the connector. You want to be quick about soldering the wire to
prevent the wire from heating up too much, potentially conducting heat to
the heat shrink tubing, resulting in premature shrinkage. We all know
the problem with that. |
 |
| After soldering on the center wire, do you best to shrink
the tubing over the entire center terminal to prevent shorts. In this
example you can see the yellow tubing slipped off one side. That's not
ideal, but it will work OK. If this happens, use the best
location with insulation to place the ground wire on the threads to pinch in
the base, minimizing the risk of a short. |
