Installing the tips
Quick Connect Flex Solder Tips Kit
Follow these steps to attach a Flex solder tip assembly and P7300 probe to a
circuit board.
1. Identify a location on the circuit under test where the Flex solder tip can be
placed and soldered. To avoid damaging the tip, do not bend the flexible
substrate to a radius tighter than 1/8-inch (3.2 mm).
2. Solder the tip leads to test points on your circuit board. For optimum
performance and signal integrity, keep the lead lengths equal and as short as
possible. Use tweezers to bend the leads, if necessary.
3. To protect the tip and soldered connection, secure the tip to the circuit using
double-sided tape, glue, or the fastener kit that came with the probe. For
optimal signal integrity at higher frequencies (≥8 GHz), insert a 20 mil
mm) or thicker insulated spacer between the tip and the circuit board.

Replacing the tip wires
The 8-mil wires that are pre-soldered to the tips need to be replaced periodically,
due to normal use. Use the following procedure to replace the wires.
1. Carefully apply a soldering iron to the via on the flex tip and remove the

If a small piece of wire is in the via, heat the solder and use another piece of
wire to push the wire fragment from the via.
4. Heat the s
older in the via and insert the bent end of the new wire into the via,
until it bottoms against the flex tip.
5. Cut the e
xcess lead on the bottom of the flex tip.
6. Repeat if necessary on the other tip input.

Bandwidth and rise time are similar to
the short flex solder tip, but are also
dependent upon the bandwidth of the
interposer used.
Performance is determined by the probe and tip used with the square
pin adapter.
