Abstract:
1. A ball grid array resistor network, comprising: a) a substrate having a first and a second surface; b) a plurality of resistors disposed on the first surface; c) a plurality of conductors, disposed on the first surface and electrically connected to an end of at least one resistor; d) a first insulating layer located over the resistors and the conductors; e) a ground plane located on the first insulating layer; f) an second insulating layer located over the ground plane; g) a plurality of vias extending through the first and second insulating layers, the vias each having a first and a second end, the first end electrically connected to the conductors; h) a plurality of ball pads located over the second end of the vias and partially over the second insulating layer, the ball pads electrically connected to the second end of the vias; and i) a plurality of electrical interconnects attached to the ball pads.
