Operation

Project Manager

Project Manager

Launch SanjVIEW from the Windows 10 start screen shortcut; once the license verifies, the Project Manager window opens. From here you can select:

Key features of the Project Manager window:

Beginning thermal imaging on a new device:

  1. Place the device under test (DUT) on the probe station.
  2. In Project Manager, confirm all components show a green status light (unless the NIR camera is unavailable).
  3. Select the desired illumination option and "Channel Number," and focus the microscope. A live DUT image appears on the right of the screen.
  4. Check the "Auto" box under LED Brightness for automatic brightness optimization (Visible Camera only).

Note: When imaging with infrared light (IR), Transient Thermoreflectance options are unavailable, and LED illumination is disabled during an IR imaging session.

Viewing temperature response in DC mode: while Project Manager is running, approximate temperature values display on the camera measurement window, scrolling as an average of the drawn Region of Interest (ROI) (or the whole image if no ROI is drawn). Use the rectangle tool to draw an ROI. DUT bias controls let you select outputs and voltage while acquiring images; the TC-100 stage can be used (~100 mA/V), or the Relay output can be selected from the pulldown. Select the TC-100 tab and press "TC-100 State on" to read the thermocouple value (useful for setting IR camera gain). Right-click the image window to save the acquired image and its color palette.

Transient Thermoreflectance (TR)

Transient Thermoreflectance (TR)

Acquires new thermal imaging data for pulses between 50 µs and 5 ms (transient).

Key features:

Example procedure — obtaining a transient measurement:

  1. Turn off "Int Vo 20mA Range" in the Project Manager.
  2. Set "DUT Pulse" to the desired pulse width (example: 500 µs).
  3. Set "Voltage to Device" (example: 6.0 V) and select "Update Values."
    1. Switch to "Thermal Imaging" mode.
    2. Confirm the device is heating as expected for the 500 µs delay.
  4. Set "Image Delay(s)" to 0 to initialize delay to 0 µs (you can start at any initial delay time).
  5. Go to File → Setup Sweep.
  6. Enter "Number Delay Images" (example: 51).
  7. Enter "Delay Steps(s)" (example: 10.0 µs) — software will take 51 images at 10 µs steps starting at 0 s (0–500 µs).
  8. Enter "Ave time per frame(s)" (example: 5 s per image).
  9. Enter the "Base File Name" to save under.
  10. Select an ROI with the "Draw ROI" tool.
  11. Press "Start."
  12. The software steps through the thermal transient automatically and shuts off voltage on completion. A thermal image is averaged and saved at the configured interval (example: every 5 s; 255 s total for 51 points, 4 min 15 s).
  13. Once done, exit and open the saved data in SanjANALYZER.

The transient response of an ROI can be watched live in the "Region Mean Graph" tab (lower-left) by selecting a region with "Draw ROI."

Movie Mode (TR and IR)

Movie Mode (TR and IR)

Acquires quasi-steady-state thermal images for pulses longer than 5 ms. Used to view longer-timescale IR and TR waveforms. In TR mode, SNR may be reduced relative to Transient/FA modes — localize thermal events first, then use Movie Mode for further study.

Key features:

Setting the time window: Options → Software tab → "Movie Mode Length" dropdown; sets the averaging time window to 3–30 seconds.

Example procedure — obtaining a Movie Mode image:

  1. Connect the DUT to Voltage Out (AUX Output optional).
  2. Select biasing conditions via the "Device Control" panel and click "Update Values."
  3. While the image averages, use the ROI tool, scale bars, and Thermal Image Display tool to optimize the image.
  4. Once the desired thermal image is achieved, save a data file for further analysis and output.

FA Mode (TR and IR)

FA Mode (TR and IR)

A simplified differential-imaging mode for quick fault localization.

Key features:

Calibration — Quick Start

Calibration — Quick Start

Calculates the thermoreflectance coefficient (TR) or emissivity (IR) of specific device surfaces. Accurate temperature readings depend on a coefficient obtained via calibration. Coefficient maps can be produced for point-by-point calibration. The module thermally cycles the DUT while reading the thermocouple back, continuously averaging coefficients across cycles to raise SNR.

Key features:

Verifying calibration using TCAT-100 in pulsed mode: set up a test sample as for calibration, launch Pulsed Mode software, select TCAT-100 as the output device, and enable thermocouple readback to simultaneously display the thermocouple signal alongside TR or IR measurement data. Calibrated IR camera results should closely overlap thermocouple results. Note: the thermocouple used with the TCAT module has a response time of ~0.5 s, so it may be necessary to lengthen the timescale to see an accurate response.

SanjANALYZER™ — Thermal Image Analyzer

SanjANALYZER™ — Thermal Image Analyzer

A fully integrated analysis package for low-frequency and transient thermal imaging data. Capabilities:

Key features:

Example procedure — analyzing a transient thermoreflectance image series:

  1. Select the first image of the transient series.
  2. Enter the "number of images in the series" (example: 51).
  3. Select an ROI box on the area of interest (example: a 5 µm gold heater).
  4. Select "Process Series." The software steps through the series and plots data in "ROI Mean Series" (bottom left); right-click the y-axis to autoscale.
