Abstract
An IC handler affords ICs to be tested for a sufficiently long period of time for them to take up either heat or cold. A turntable is formed with N circular rows of positioning recesses lying on concentric circles. ICs to be tested are successively fed into the positioning recesses of either the outermost or innermost row. When each of the ICs makes a revolution with the rotation of the turntable, the IC is crossed over into one of the positioning recesses of another one of the rows. After the IC has made at least one revolution, it further travels through a predetermined angle from the cross-over position to a position of delivery to a testing section, and is then delivered to the testing section.
