Abstract
A handler for semiconductor devices has a positioning wheel with a number of platforms that hold semiconductor devices, a mechanism for rotating the positioning wheel, and a mechanism for elevating and lowering the platforms. A semiconductor device is inserted into one of the platforms, the positioning wheel rotates until the platform is aligned with the leads of a semiconductor device tester. The platform is then raised placing the leads of the tester in contact with the semiconductor device. After testing is complete, the platform is lowered to the surface of the wheel and the wheel is rotated further to align the platform with an apparatus for storing semiconductor devices. The tested semiconductor device is ejected from the platform into the sorting apparatus.
