Abstract:
A system, method, and device for applying conductive bonding material to a substrate are disclosed. The method includes providing conductive bonding material in a plurality of cavities of a mold. A total number of cavities in the plurality of cavities being greater than a total number of at least one conductive pad of a circuit supporting substrate corresponding to the mold. The conductive bonding material in the mold is heated to a reflow temperature of the conductive bonding material. At least one wettable surface is placed in substantial contact with the heated conductive bonding material in at least one cavity. The mold and the corresponding circuit supporting substrate are brought in close proximity to each other such that the heated conductive bonding material in at least one cavity comes in contact with at least one conductive pad of the corresponding circuit supporting substrate.
