FIXTURE TO CONSTRAIN LAMINATE AND METHOD OF ASSEMBLY

摘要

A fixture assembly and method of forming a chip assembly is provided. The fixture assembly includes a first plate having an opening sized to accommodate a chip mounted on a laminate. The fixture assembly further includes a second plate mated to the first plate by at least one mechanical fastening mechanism. The fixture assembly further includes a space defined by facing surfaces of the first plate and the second plate and confined by a raised stepped portion of at least one of the first plate and the second plate. The space is coincident with the opening. The space is sized and shaped such that the laminate is confined within the space and directly abuts the stepped portion and the facing surfaces of the first plate and the second plate to be confined in X, Y and Z directions.
