Calibration Module

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.
