ABSTRACT:
A ball grid array resistor network has a planar substrate formed of an organic material. The substrate preferably is a printed circuit board. The substrate has a top and bottom surface. A ball pad is located on the bottom surface. A low temperature resistor is located on the bottom surface and is connected to the ball pad. A solder mask is located over the first surface except for the ball pads. A conductive ball is attached to the ball pad. A reflowed solder paste connects the conductive ball to the ball pad. Several embodiments of the invention are shown.
