Abstract
Operation methods of test handler are disclosed. The pick-and-place apparatus picks up semiconductor devices from first loading compartments arrayed in a matrix on a first loading element, moves, and places onto second loading compartments arrayed in a matrix on a second loading element. Pickers of the pick-and-place apparatus pick up the semiconductor devices from the first loading compartments and place them selectively onto a plurality of adjacent odd rows or a plurality of adjacent even rows of the second loading compartments during one operation. The pick-and-place apparatus includes a relatively large number of the pickers, preferably arrayed in a matrix, and thus performs loading and unloading of semiconductor devices at a relatively high speed.
