Patent ID: 7923989

Claim:
A test handler comprising: a loading unit configured to load semiconductor devices from customer trays onto a test tray including a number of inserts arranged in a matrix pattern; a test chamber configured to perform a test for the semiconductor devices loaded on the test tray; a pushing unit having at least one match plate configured to push the test tray located in the test chamber, at least a pair of lower support member and upper support member movably mounted to the pushing unit, respectively, and a press unit configured to operate the match plate, the match plate having a number of pushers arranged in a matrix pattern to correspond to the inserts arranged in the matrix pattern on the test tray, and the match plate being slidably mounted between the lower support member and the upper support member with a gap between an upper end of the match plate and the upper support member; a position control unit configured to adjust a position of the match plate to compensate a vertical deviation between the match plate and the test tray; and an unloading unit configured to unload the semiconductor devices loaded on the test tray onto the customer trays after a test for the semiconductor devices is completed, wherein the vertical deviation is caused by a thermal expansion or contraction of any one of the match plate and the test tray; and wherein the position control unit moves the lower support member to adjust a position of the match plate to compensate for the vertical deviation, thereby allowing the positions of the pushers and the inserts to be coincided with each other for the test.
