Abstract:
1. A circuitized substrate comprising first and second dielectric layers, a first conductive layer positioned on said first dielectric layer and a second conductive layer positioned on said second dielectric layer, said first and second conductive layers each including a plurality of conductive lines, said first conductive layer further having a first pattern of electrical component contact sites and a plurality of second patterns of electrical component contact sites substantially surrounding said first pattern of electrical component contact sites and spaced from said first pattern of electrical component contact sites, each of said patterns of electrical component contact sites including at least twenty such contact sites, each of said second patterns of electrical component contact sites surrounding said first pattern, and a first plurality of said conductive lines interconnecting selected ones of said contacts sites of said first pattern of electrical component contact sites with selected ones of said contact sites of said second pattern of electrical component contact sites, selected ones of said first plurality of conductive lines each including selected ones of said conductive lines of said first conductive layer and said conductive lines of said second conductive layer, while selected ones of others of said first plurality of conductive lines including only conductive lines of said first conductive layer, said conductive lines of said second conductive layer being electrically coupled to said selected ones of said conductive lines of said first conductive layer, said selected ones of others of said first plurality of conductive lines being of substantially the same length.
