Abstract
A microchip handling system has a pair of probes with suction cups for handling microchips. An improved microchip holding device is used in lieu of the suction cups to pick up and hold microchips. The microchip holding device has a head accommodating an annular sleeve that retains the microchip in spaced holding relationship relative to a body. The sleeve establishes a large annular space whereby the vacuum force has a large surface area for holding the microchip in engagement with the sleeve.
