Patent ID: 8181846

Claim:
A method of depositing conductive bonding material into a plurality of cavities in a mold, the method comprising: placing a fill head in substantial contact with a mold comprising a plurality of cavities that contain air therein, wherein the fill head comprises a sealing member that substantially encompasses an entire area including the plurality of cavities that contain air therein and that are to be filled with conductive bonding material; holding conductive bonding material within the fill head above the plurality of cavities; creating a vacuum in at least one region in the fill head that is situated immediately above the conductive bonding material held within the fill head, wherein the vacuum evacuates the air contained in the plurality of cavities through the conductive bonding material held within the fill head; forcing, after the vacuum has been created, the conductive bonding material out of the fill head toward the plurality of cavities in the mold; and providing the conductive bonding material into at least one cavity of the plurality of cavities contemporaneous with the at least one cavity being in proximity to the fill head and encompassed by the sealing member.
