Abstract
A transfer device of a handler for testing semiconductor devices is provided in which a pitch between each of a plurality of picker heads may be adjusted without replacing a cam plate. The transfer device may include a base part, a plurality of picker heads movably mounted on the base part, and a cam plate movably mounted on the base part and having a plurality of inclined cam grooves formed therein. Each picker head is connected to a corresponding cam groove by a connection part extending therebetween, with an end of each connection part movably coupled to its respective cam groove. A driving unit reciprocates the cam plate so that, as the ends of the connection parts move within the cam grooves, a position of the picker heads may be varied.
