ABSTRACT:
A reusable centrifuge fixture is disclosed for holding small parts, such as integrated circuit chips, during high speed rotation. The fixture is made of a moldable material having a depression formed therein conforming to the contours of the part. The fixture is made by pouring the moldable material into an open cavity of a form and the part to be centrifuged, or a replica thereof, is impressed into the surface of the moldable material prior to curing. A permanent magnet is used in conjunction with the fixture to hold the part within the centrifuge machine during set-up of the machine.
