A ball grid array package includes a substrate with a top and bottom surface. A circuit component is located on the bottom surface. The circuit component has a pair of ends. A pair of conductors are located on the bottom surface. The conductors are connected to the ends of the circuit component. A conductive epoxy covers a portion of the conductors and a portion of the bottom surface. The conductive epoxy is in electrical contact with the conductors. A ball is connected to the conductive epoxy. The conductive epoxy provides an electrical connection between the conductor and the ball. The ball is preferably copper and is subsequently coated to prevent corrosion. Other embodiments of the invention are shown in which the balls are omitted and in which the conductive epoxy is used to fill vias in a substrate.
