Abstract
The bus bar includes a first bus bar layer formed of a first generally uniform thickness of a first bus bar conductor; a first dielectric layer overlying a top surface of the first bus bar layer; and a second bus bar layer formed of a second generally uniform thickness of a second bus bar conductor overlying a top surface of the first dielectric layer and the top surface of the first bus bar layer wherein: the first bus bar layer includes a first via for receipt of a first electrical lead of an electrical component and a second via for receipt of a second electrical lead of the electrical component and wherein: the first dielectric layer and the second bus bar layer each include a via aligned with the first via wherein the first electrical lead is extendable from beneath the first bus bar layer through the first dielectric layer and through the second bus bar layer.
