Patent ID: 6906508

Claim:
A vacuum ring for use in conjunction with a test plate on a component testing system for testing DUTs such that each DUT has a cross sectional area less than a predetermined minimum cross sectional area, the vacuum ring comprising: a base; and means for ejecting DUTs from the test plate, said means including an eject hole pattern defined by the base for discharging compressed gas toward the DUTs; wherein the eject hole pattern includes a plurality of closely spaced apart individual holes such that each of the individual holes has a cross sectional area that is less than the size that would be large enough to receive a DUT having the predetermined minimum cross sectional area; and wherein the base does not include a resistance heating element or a plasma generating electrode; whereby the number of holes affecting a particular DUT for DUT ejection purposes is dependent on the cross sectional size of that particular DUT.
