Abstract
A microchip tray handling apparatus has microchip loading and receiving units for supplying microchips to a microchip tester and receiving tested microchips. The units have tables to support stacks of trays containing microchips. Each unit has a tray holding assembly for raising a stack of trays to allow a bottom tray to allow a bottom tray to be moved along the table. Pick, invert and place probes remove microchips from the trays and place tested microchips back into the trays.
