Patent ID: 7768286

Claim:
An electronic device testing apparatus, comprising: a first temperature measurement device for measuring an internal temperature of an electronic device based on a detection signal from a temperature detector provided inside the electronic device; a second temperature measurement device provided outside of said electronic device for measuring a standard temperature and for measuring a temperature of said electronic device in a state of being thermally connected to said electronic device; a temperature control device thermally connected to said electronic device for controlling a temperature of said electronic device by heating or absorbing heat; and a calibration means for calculating a correction value for said first temperature measurement device from a difference of a first measurement temperature by said first temperature measurement device and a second measurement temperature as a standard temperature by said second temperature measurement device in a state, where said temperature control device and said electronic device are made to be a predetermined constant temperature; and wherein said internal temperature of said electronic device to be tested is measured by said first temperature measurement device, the internal temperature of said electronic device is specified based on the obtained first measurement temperature and said correction value calculated by said calibration means, and the internal temperature of said electronic device is made to be said predetermined constant temperature by controlling said temperature control device to heat or absorb heat.
