Device Probing Microscope Camera

PN0293

The primary use of the probing camera is to display small areas on electronic devices when making electrical connections using probes.  The camera can also be used to capture images of the unit under test for use with the Picture Overlay software tool.  See the Thermalyze HTML Help for detailed information about Picture Overlay.

    Overview

Camera

Sentris probing cameras are USB3 Vision compliant color digital camera with 1280 x 960 pixel resolution, image capture rate of 30 frames-per-second and is USB powered.

Lens

The Semiconductor Probing Lens is used to probe contact sites down to 10 x 10 µm on semiconductor devices (see Figure 1).  This lens comes with 0.5X, 1X, and 2X objectives.  The lens has manual zoom and focus is performed by adjusting the height of the probing camera.

  • The 0.5X objective provides magnification from 0.3X (12 x 16 mm FOV) to 2.0X (1.6 x 2.4 mm FOV) with 175 mm working distance.

  • The 1X objective provides magnification from 0.6X (6 x 8 mm FOV) to 4.0X (0.8 x 1.2 mm FOV) with 82 mm working distance.

  • The 2X objective provides magnification from 1.2 X (3 x 4 mm FOV) to 8.0X (0.4 x 0.6 mm FOV) with 35 working distance.

LED Ring Lights

To illuminate targets when capturing probing camera images, an LED Ring Light (see Figure 2) is mounted on the end of the Probing Camera lens.  The LED Ring Lights provide cool lighting and does not require positional adjustment as it is always aimed directly at the target.  An adjustable dimmer knob controls the amount of light illuminating the target.
