Overview

The TriMode Resistor and Extended Resistor
Solder Tips allow you to create customized,
hands-free connections from your circuit to
Tektronix P7500 Series TriMode probes.

Integral resistors on the tips include

Using the Solder Tips

General recommendations:

The tips cannot support the weight of the
attached probe. Therefore, before you
solder the resistors or ground wires to the
circuit board, position the tips so that you
can secure the probe to the circuit board
to relieve strain on the tips and the solder
connections.

Use a flux pen to add flux to the solder tips
and to your test points. The flux makes
soldering easier.

Only use ESD-approved soldering irons and
no-clean flux

If you are using the tip ground connection,
use the wire provided in your accessory kit
with the P7500 Series TriMode probes.

Procedure

1. Choose a location where the solder tip
resistor leads can reach your test points.

If you are using a ground connection, note
which solder tip ground via is closest to your
circuit ground.

2. Apply solder to the test points on your
circuit.

3. If you are not using the ground, solder the
tip resistor leads to the test points on your
circuit, clip off any excess, and go to step 10.

If you are using a ground wire, apply solder
to the solder tip ground via that you chose.

4. Position a length of wire about 1-inch long
under the s

5. Heat the solder tip via and insert the wire.

6. Cut the excess wire on the other side of the

solder tip, flush with the board.

7. Cut the ground w

wire as short as
performance.

8. Solder the ground wire to the circuit and
clip off any excess wire.

9. Solder the resistor leads to the test points on
your circuit and clip off any excess leads.

10. Push the end of t
until it seats in the probe head.

11. For a secure mechanical connection, use
double-sided tape or hot glue to secure the
tip to your circuit.

12. Secure the probe to the circuit board with
tape or hook-and-loop strips.

Replacing th e Re

sistors

The resistors that are presoldered to the tips need
to be replaced pe

riodically, due to normal use. A
kit of replacement resistors is available (order
part number 020-

2937-00).

Procedure

1. Carefullyapplyasolderingirontotheviaon

the tip board and

remove the existing wire.
Work quickly with a low-heat soldering
iron.

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.

2. Add fresh solder to the via, if necessary.

3. If you are replacing the resistor on the

extended resisto

r tip, cut one lead of the

resistor to approximately 0.6" (15mm).

If you are replacing the resistor on the
(shorter) resistor tip, cut one lead to 0.2"
(5mm).

4. If you are replacing the resistor on the
extended resistor tip, slide a piece of tubing
included with the resistor kit over the lead.
This will insulate the resistor lead.

5. Heat the solder in the via and thread the cut
resistor lead into the via until the:

esistor tip.

you are replacing the resistor on the (shorter)
resistor tip.

6. Cut excess l ead on the bottom of the board.

7. Cut the remaining resistor lead to 0.1"

(2.5mm).
