A calibration module with a thermocouple located under an electrically good
semiconductor chip is used to calibrate the heat lamp in a chip removal tool.
The calibration module is identical to the modules to be worked on in the
chip-removal tool with the exception of the addition of the thermocouple and the
use of solder with a higher melting temperature. The higher melting temperature
solder is used to prevent continuous reflowing of the solder joints, minimizing
degradation of those solder joints with use of the calibration modules, thus
prolonging the life and improving the reliability of costly calibration modules.
