Abstract:
1. A pick-and-place apparatus for transferring and loading semiconductor devices between a first loading element, on which semiconductor devices are loaded at a first row interval, and a second loading element, on which the semiconductor devices are alternately loaded at second and third row intervals, the pick-and-place apparatus comprising: a multiplicity of picking unit modules, each of which has at least one or more picking units; and an interval regulation apparatus for regulating intervals between the picking unit modules at first, second, and third modes, wherein, the interval values of the first, second, and third rows are different from each other; the intervals between the picking unit modules are all regulated to be identical to the first row interval at the first mode; the intervals between the picking unit modules are alternately regulated to the second row interval and the third row interval in turn at the second mode; and the intervals between the picking unit modules are alternately regulated to the third row interval and the second row interval in turn at the third mode.
