Mounting a device on the cold plate

Rev. CUpdated 2026-09-30

Mount a device on the temperature-controlled cold plate so that calibration and measurement share the same thermal boundary.

Before you start

Switch the heating current off and confirm the door interlock indicator is green. Let the cold plate reach its set temperature.

Mount the device

  1. Clean the cold plate and device baseplate with isopropyl alcohol.
  2. Apply thermal grease in a thin, even layer, or place the TIM pad for TDIM measurements.
  3. Position the device with the fixture pins and tighten the clamp to the torque in the table below.
  4. Connect the heating, sense and gate leads to the DUT connector panel.
Package Clamp torque Fixture
TO-247 0.6 N·m F-TO247
62 mm module 3.0 N·m F-M62
EconoDUAL 3.0 N·m F-ECD3
Note

Use the same fixture and torque for calibration and measurement. Remounting the device invalidates the K-factor.
