ABSTRACT:
The invention comprises an extended input system by which additional component supply stations are located out of reach of the pick and place heads of a machine for handling surface mountable components and are selectively addressable by a supply shuttle which fetches individual components and delivers each component selectively to a test pocket or a utility pocket of a transfer assembly, from which the components are retrievable by a pick and place head of the onserter. In a preferred embodiment, the transfer assembly provides a second shuttle on which the utility and test pockets are mounted for movement back and forth between the supply shuttle unload station to a pick-up station of the head, and the component testing occurs during transit of the transfer shuttle.
