Claim:
1. A method for testing MEMS devices using a wafer level centrifuge (WLC) system comprising a base centrifuge system and a cassette mounting hub coupled to the base centrifuge system, the method comprising: inserting one or more MEMS wafers into one or more cassettes; coupling the one or more cassettes to the cassette mounting hub; applying a controlled acceleration profile to the one or more MEMS wafers via the base centrifuge system, wherein each of the one or more MEMS wafers having one or more MEMS devices formed thereon; removing the one or more MEMS wafers from the one or more cassettes; and determining if the one or more MEMS devices from the one or more MEMS wafers has physical problems; wherein the one or more MEMS wafers and the one or more cassettes include two or more MEMS wafers and two or more cassettes configured in a precision balanced manner on the cassette mounting hub.
