Clean the soldering iron tip and add a small amount of solder to the very tip.
This may take a few tries because the solder may tend to ball up and move
away from the tip.
Figure 2-35
shows a small amount of solder on the tip of the
soldering iron.

Installation of ZIF tip. Connect the ZIF tip to the ZIF probe head as shown in
Figure 2-30
and
Figure 2-31
. This allows the probe to be used as a handle for
the ZIF tip to allow positioning in the DUT. Position the lead wires on the target
points and then briefly heat the solder joints. There should be enough solder to
form a good fillet and enough flux to make the joint shinny. There should not
be so much solder that the big solder ball is formed that could cause a solder
bridge or overheat the leads on the ZIF tip. This is shown in
Figure 2-36
.
