Patent abstract
A land grid array (LGA) land pad having reduced capacitance is disclosed. The conductive portion of a land pad that overlaps a parallel ground plane within the substrate is reduced by one or more non-conductive voids though the thickness of the conductive portion of the land pad. The voids may allow the contact area of the land pad, as defined by the perimeter of the land pad, to remain the same while reducing the conductive portion that overlaps the parallel ground plane. Capacitance between the land pad and the parallel ground plane is reduced by an amount proportional to the reduction in overlapping conductive area.
