ABSTRACT:
A system for producing integrated circuit devices includes first and second integrated circuit processing stations. The first station produces an output stream of individual, separate devices for delivery to the second station. A drum buffer receives the individual devices from the first station, selectively stores the individual devices, and dispenses the stored devices on a substantially last-in first-out basis to the second station. The drum buffer includes a plurality of device carrying channels axially along the length of the drum to receive the devices being selectively stored by filling the respective channels as the drum is rotatably indexed in one direction, and to empty the stored devices from the respective channels as the drum is rotatably indexed in an opposite direction.
