As electronic devices continue to decrease in size, heat
generation and thermal dissipation become increasingly important. Micro can
measure and display the temperature distribution over the surface of
devices, enabling quick detection of hot areas which can decrease efficiency
and frequently lead to early failure.
A Micro system includes several important hardware
components that are essential when analyzing or troubleshooting
semiconductor devices. The optical mounting table provides a sturdy platform
with vibration isolation on which to perform sensitive testing. Precise
camera focusing and positioning is accomplished using the vertical focus
stage. Areas of interest on a device can be quickly and accurately
positioned within the camera’s field-of-view using the XY stage. The thermal
stage provides both heating and cooling for precise device temperature
control in order to locate short circuits and to compensate for pixel
emissivity variations.
Micro can also be used to perform failure analysis on small
circuit boards. Defective and marginal components can be identified using a
proprietary software tool called Model Board Comparison and the Find Shorts
software tool helps detect and locate difficult-to-find short circuits.
