Abstract
A resistor network has a substrate with top and side surfaces. Resistors are located on the side surfaces. Several side conductors are located on the side surface and are electrically connected to the resistors. Several top conductors are located on the top surface and are electrically connected to the side conductors. Each top conductor has a cavity. A solder sphere is partially located in the cavity and is electrically and mechanically connected to the top conductor by reflowed solder paste. A cover coat covers the side conductors and the resistors. The resistor network provides a high density of resistors per unit area.
