Abstract

A plurality of electrical interconnections may be formed in an electrical device including a first component having a plurality of contact pads and a second component having a plurality of contact pads. The two components are placed in a confronting spaced relationship such that each contact pad of the first component locationally corresponds to one of the contact pads of the second component. The contact pads of the second component are further arranged such that at least two of the contact pads are laterally offset relative to their locationally corresponding contact pads on the first component with one of the at least two contact pads being offset in a first direction while the other is offset in another direction. A mass of conductive material is disposed between each contact pad of the first component and its corresponding contact pad of the second component. The masses of conductive material may be formed into columnar members wherein the columnar members are skewed when formed between a pair of relatively offset contact pads.
