Abstract:
An apparatus for substantially planarizing a plurality of outer surfaces of an array of solder bumps attached to a bumped device, comprising:a planarization member engageable with at least some of the plurality of outer surfaces, the planarization member applying a planarization action on one or more of the plurality of outer surfaces to substantially planarize the solder bumps; a securing element engageable with the bumped device to securely position the bumped device during engagement of the planarization member with the outer surfaces; and a load device engageable with at least one of the bumped device or the planarization member to urge the at least some outer surfaces of the bumped device into engagement with the planarization member, wherein the securing element includes a retaining clip engageable with a substrate of the bumped device and the planarization member includes a substantially flat surface in contact with the at least some outer surfaces, the load device including a centrifuge engageable with the planarization member, the planarization action comprising a centrifugal force that compresses and mechanically flattens the one or more outer surfaces against the flat surface.
