Classification: CPC H  G | IPC G  H

Claim 4:
5. An apparatus for determining a critical temperature of a semiconductor package, the apparatus comprising:
a heater configured to apply heat to the semiconductor package;
a temperature sensor configured to measure successive temperatures of the semiconductor package during application of the heat;
an actuator configured to move the temperature sensor along a first horizontal direction and a second horizontal direction substantially perpendicular to the first horizontal direction;
a height sensor configured to measure heights of the semiconductor package at each of the successive temperatures during application of the heat; and
a controller configured to determine a temperature, as the critical temperature of the semiconductor package, from among the measured temperatures of the semiconductor package at a point at which a height of the semiconductor package is sharply increased so that swelling of the semiconductor package occurs.
