Claim 12:
13. An apparatus for determining critical temperatures of a plurality of semiconductor packages, the apparatus comprising:
a plurality of heaters configured to apply heat to the plurality of the semiconductor packages;
a plurality of temperature sensors configured to measure successive temperatures of the plurality of semiconductor packages during application of the heat;
a plurality of first actuators configured to move the plurality of temperature sensors along a first horizontal direction and a second horizontal direction substantially perpendicular to the first horizontal direction;
a height sensor module configured to scan the plurality of semiconductor packages along the first horizontal direction or the second horizontal direction to measure heights of the plurality of semiconductor packages at each of the successive temperatures during application of the heat;
a second actuator configured to move the height sensor module along the first horizontal direction and the second horizontal direction; and
a controller configured to determine temperatures, as the critical temperatures of the plurality of semiconductor packages, from among the measured temperatures of each of the plurality of semiconductor packages at points at which heights from among the measured heights of the plurality of semiconductor packages are sharply increased so that swelling occurs.
