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.
