Patent ID: 6928727

Claim:
A method for manufacturing an electrical connection unit, the method comprising: (a) providing a first insulative base and a first set of contacts, said first insulative base having: i) a first side located in a top plane, ii) a second side opposite the first side, and iii) a plurality of apertures extending between said first side and said second side; (b) inserting said first set of contacts into respective apertures of said first insulative base, said contacts each having a first end and a second end, said first end being positioned near the top plane of said first side; (c) applying a solder positioning device adjacent said first side of said first insulative base in the top plane, said solder positioning device providing a plurality of cavities positioned in alignment with respective apertures of said first insulative base, wherein said first ends of said first set of contacts are positioned adjacent to cavities within said solder positioning device; (d) inserting solder portions into said cavities, thereby contacting said respective first ends of said first set of contacts with solder portions; (e) heating said solder portions, thereby fusing said solder portions with respective first ends of said first set of contacts; and (f) forming a first electrical connection unit comprising an array of fused solder portions in said top plane.
