  • Patent number: 4869636
    Abstract: A package handling apparatus for presenting circuit packages to a test head is provided which uses a soft handling approach throughout the system. The handler works with a plurality of sticks, with each stick adapted for holding a plurality of packages in a substantially horizontal linear array, with the linear array defining a linear axis for the stick. The handler includes an input elevator element for receiving a first stick loaded with a first package, for moving the first stick vertically to an index level. An input drive moves the first stick horizontally to an index position. A first pick-up removes the first package from the first stick and then moves the first package to a stage pick-up position. A stage element receives the first package, and presents it to the test head for testing. Once tested, the stage element moves the package to a stage exit position. A stage pick-up then places the first package in a stage row stick.
