Abstract:
1. An electrical interconnection between a first element and a second element, including: a first portion of a ribbon material ultrasonically bonded to a first element, the ribbon material having a rectangular cross section; a length of the ribbon material, continuous with the first portion, extending to a second element spaced apart from the first element; and a second portion of the ribbon material bonded to the second element, wherein the first portion of the ribbon material ultrasonically bonded to the first element includes a first bonded portion, a second bonded portion, and a third bonded portion, the first bonded portion being closest to the second element in comparison to a position of the second bonded portion and the third bonded portion, the second bonded portion being positioned between the first bonded portion and the third bonded portion, wherein when measured in a direction along which the ribbon material extends (1) a distance between a centerline of the second bonded portion to a centerline of the first bonded portion is less than (2) a distance between a centerline of the third bonded portion to the centerline of the second bonded portion, such that a length of ribbon material between the centerline of the third bonded portion and the centerline of the second bonded portion is greater than a length of ribbon material between the centerline of the second bonded portion and the centerline of the first bonded portion.
