ABSTRACT:
A method of forming a solder ball structure comprising the steps of 1) obtaining a first object having at least one high melting point solder ball, each solder ball having a corresponding BLM containing a low melting point solder, each solder ball having an outer surface, top and bottom, each BLM having a top and bottom, the bottom of each solder ball in contact with the top of the corresponding BLM over a portion of the outer surface, the bottom of each BLM in electrical communication with the first object; 2) obtaining a template having a first surface; 3) applying a disjoint area of low melting point solder paste to the first surface of the template; 4) interacting the top of each solder ball and the solder paste; and 5) reflowing each solder ball and disjoint area of solder paste while each solder ball and disjoint area of solder paste are interacted.
