## Next-Generation Thermal Imaging in Electronic Failure Analysis with the Optotherm MW640-15 MWIR Camera

Optotherm is making waves in the analysis of electronic circuit failures and microscopic temperature measurements with its high-precision MWIR thermal imaging camera, the MW640-15.

### Features of the Innovative Thermal Camera
The MW640-15 is specifically designed for front and backside integrated circuit (IC) failure analysis and lock-in thermography applications. Beyond standard MWIR systems, its NETD sensitivity of less than 20 mK shortens test times, while offering a resolution down to 1 micrometer, allowing for clear distinction of details in integrated circuits.

The camera features a 640 x 512 pixel 15 µm pitch MCT detector, cooled to 80 K by a Stirling engine. With frame rates of 115 Hz (full frame) and 1,550 Hz (window mode), it enables high-resolution analysis of the thermal behavior of active IC devices.

### MW640-15 Specifications

• NETD sensitivity: < 20 mK
• Detector resolution: 640 x 512 pixels
• Pixel pitch: 15 µm
• Cooling: 80 K with Stirling engine
• Frame rates: 115 Hz (full frame), 1,550 Hz (window mode)
• IC feature distinguishability: 1 µm
• Temperature detection sensitivity: < 0.0001 °C

### Application Areas and System Integration
The device is suitable for hot spot detection, junction temperature measurement, and transient analysis in semiconductor devices. The MW640-15 can be used independently or integrated into the Optotherm Sentris system to provide turn-key solutions.

Rich Barton, President of Optotherm, stated, "We developed the MW640-15 for failure analysis engineers who demand high spatial resolution, precise measurements, and IC backside analysis capability."
