ABSTRACT:
The present invention relates to a test tray for a test handler. According to this invention, there is disclosed a technique that an insert loaded in a loading part which is arranged in a matrix pattern in a frame of the test tray allows an amount and direction of free movement thereof to be determined in accordance with a location of the loading part, where the insert is loaded, on the matrix, thereby enabling a thermal expansion or contraction of a match plate or the test tray to be compensated.
