Abstract
An apparatus for inserting IC packages into sockets on a burn-in board and for extracting IC packages therefrom includes a plurality of loader/unloader mechanisms affixed to a rotatable platform, the platform being adapted to support one or more burn-in boards and to position sockets mounted on the burn-in boards beneath the loader/unloader mechanisms one row at a time. The loader/unloader mechanisms include a vacuum means for lifting IC packages and pneumatic cylinders for transporting the packages to and from the burn-in boards. IC packages are gravity fed along a delivery channel both to and from the loader/unloader mechanisms by rotation of the platform.
