Abstract:
1. A system for providing conductive bonding material into a plurality of cavities in a circuit supporting substrate, the system comprising: at least one conductive bonding material placement device for providing conductive bonding material into at least one cavity of a circuit supporting substrate, the conductive bonding material placement device comprising: means for providing one of linear and rotational motion to at least one of the fill head and the circuit supporting substrate while the fill head is in substantial contact with the circuit supporting substrate; a means for bringing a second circuit supporting substrate in close proximity to the circuit supporting substrate, wherein at least one receiving pad on the second circuit supporting substrate substantially contacts the conductive bonding material of the at least one cavity, wherein the at least one receiving pad extends from a surface of the second circuit supporting substrate and at least a portion of the at least one receiving pad is inserted into the conductive bonding material in the at least one cavity; and means for filling the at least one cavity such that at least one electrical contact in one or more layers of the circuit supporting substrate intersecting with the at least one cavity is brought into electrical contact with the conductive bonding material in the at least one cavity, wherein the at least one electrical contact terminates at a sidewall of the at least one cavity.
