Abstract: An apparatus for processing electronic circuit devices includes an infeed station, a first inspection station, an inverter station, a second inspection station, a sorting station, and an outfeed station. A linear transport mechanism having side edges transports a first work piece containing a plurality of electronic circuit devices through the stations along a linear path. The inverter station holds an empty second work piece above the transport mechanism in an inverted orientation. The inverter station also includes an elevator for lifting the first work piece vertically into an abutting relationship with the second work piece, and an inverting mechanism for inverting the first and second work pieces while maintaining them in the abutting relationship to position the electronic devices in the second work piece in the inverted orientation.

Abstract: A scanning system inspects elements, such as ICs, continuously by positioning a second tray containing elements to be inspected adjacent a scan bed in which the elements in a first tray are being scanned. Immediately upon completion of scanning of elements in the first tray, scanning begins on elements in the second tray. During scanning of the second tray, the first tray is off loaded, and a third tray replaces the first tray. The cycle is repeated continuously. Since transport and scanning operations take place simultaneously, transport delay is reduced substantially, as compared to the serial system of the prior art. When the transport, positioning, and off loading operations consume substantially less time than the scanning operation, a fresh tray of elements always awaits scanning upon completion of scanning of elements in a tray.
