Termination Pin Removal

Termination pins can be removed with or without the probe and optional spacer plates installed.

Removing Termination Pins & Probes with the Probe & Spacer Plates Installed:

The ETR-EXT tools are designed to remove and install terminations pins from the Back Plate with the Probe and Spacer Plates in place. These tools would typically be used for field repairs where it is not practical to remove all of the probes and disassemble the Probe and Spacer Plates from the fixture. The tools are designed to remove and install termination pins in Back Plates up to .625 [15.88] in thickness when the fixture is designed around QA’s Fixture Layout Examples. Note: the Probe and Spacer Plates must be in place in order to prevent the tool from being damaged. If these plates are removed, use the standard ETR tools for termination pin removal and the ITR tools for installation.

Step 1

Remove the X Probe from the Probe Plate with QA’s PERX tools, tweezers, or needle nose pliers. Identify the termination pin from the bottom side of the Back Plate for removal and move adjacent wires and components to prepare the termination pins to be removed. This will help prevent damage to nearby contacts while the termination pin is being driven out.

Step 2

Guide the nose of the tool into the mounting hole in the Probe Plate until the nose of the tool contacts the interconnect pin on the termination pin. Make a small mark on the shank of the tool located at the top of the Probe Plate with a pencil or fine line marker. This mark will be used to gauge the set height when installing the replacement termination pin.

Step 3

The termination pins are removed by tapping lightly on the tools “striker” with a small hammer. The wireless XTDS termination pins are used with both the X50 and X75 Probes. In cases where an X75 Probe is connected with an XTDS termination, the ETRX50-EXT tool would be used, not the ETRX75A-EXT tool.

Removing Termination Pins & Probes with the Probe & Spacer Plates Removed:

The termination pin removal requires use of an ETR tool. This tool is used when a termination pin has been damaged and must be replaced. These tools are designed to remove the termination pins from the Back Plate once the Probe and Spacer Plates have been removed. Following these instructions will ensure that the Back Plate will not be damaged:

Step 1

Be sure that the termination pins are set flush, prior to extraction.

Step 2

The ETR tool is placed onto the interconnect pin of the termination pin and driven out by tapping lightly on the tools “striker” with a small hammer. With care, the tool will also remove the termination pins with broken interconnect pins. The tool is designed to remove termination pins in mounting plates up to .625 [15.88] in thickness. To help prevent the tool from being damaged it is recommended that the termination pin first be set to .000 with an ITR-FL tool (on termination pins set below .000, this step is not required). Because of the delicate nature of the ETRX31 and ETRX39 tool, extra care must be taken so that the tool does not get damaged. Use the ETR-EXT extended tool only when the Probe Plate and Spacer Plates are installed. The ETR-EXT tools are delicate and may buckle if proper support is not in place.
