The InfraScope II microscope is an infrared sensitive optical microscope used for temperature mapping of the microelectronic devices. Its application includes: measure Junction temperatures; observer current collapse; optimized reliability; measure thermal resistance; verify Die & solder attach; establish thermal design rules; and detection of hot spot & shorts. The system has 4 infrared microscope objectives, providing the spatial resolution from 120um down to 3um, with temperature resolution near 0.1K. The example measurement is the mapping of temperature distribution of GMR sensor when it is subjected to large sense current.
