Patent ID: 7694869

Claim:
A method of applying conductive bonding material to circuit-supporting substrates of integrated circuit chips, each such integrated circuit chip comprising: a circuit-supporting substrate; at least one electronic circuit disposed on the circuit-supporting substrate; a plurality of conductive pads disposed on the circuit-supporting substrate, each conductive pad of the plurality of conductive pads arranged at a pitch P SUBSTRATE having a value, wherein the value of the pitch P SUBSTRATE is equal to or greater than a value of a pitch P MOLD between cavities on a mold used for applying conductive bonding material to each conductive pad; and at least one non-conductive and non-pad position being a surface of the circuit-supporting substrate at the pitch P SUBSTRATE ; and wherein the method comprising the steps of: providing conductive bonding material in a plurality of cavities of the mold used for applying conductive bonding material to each conductive pad of the plurality of conductive pads disposed on the circuit-supporting substrate; heating the conductive bonding material in the plurality of cavities of the mold to a reflow temperature of the conductive bonding material; bringing the mold and the corresponding circuit-supporting substrate in close proximity to each other such that the heated conductive bonding material in at least one cavity of the plurality of cavities comes in contact with at least one conductive pad of the plurality of conductive pads and the heated conductive bonding material in at least a second cavity of the plurality of cavities comes in contact with the at least one non-conductive and non-pad position on the surface of the circuit-supporting substrate; and separating the mold from the circuit-supporting substrate, wherein, subsequent to the separating, the at least one non-conductive and non-pad position on the surface of the circuit-supporting substrate includes an indication of contact with conductive bonding material residing in at least one cavity in the plurality of cavities, wherein the indication of contact with the conductive bonding materials includes at least one of: an indentation in the surface of the circuit-supporting substrate; and conductive bonding material residue at the surface of the circuit-supporting substrate.
