Abstract: A resistor network for terminating active electronic circuits such as stub series terminated logic and emitter coupled logic circuits. The network has a substrate with top and bottom surfaces and a common via extending through the substrate. Several resistor pairs are located on the first surface surrounding the common via. Each resistor pair has first and second vias. Resistors are connected between the first and second vias. Several solder spheres are located on the bottom surface. Each of the solder spheres are electrically connected to one of the first, second or common vias.

Abstract: A fuel level indicator system that utilizes a resistor card having an arc-shaped resistive path with a first set of spaced apart conductor lines and an arc-shaped resistive ink material overlying the first set of conductor lines. There is provided a first and second set of insulative bars that are screened between and parallel to the first and second sets of spaced apart conductor lines respectively. The bars provide for decreased wear of the fuel level indicator system. The first conductor lines are formed at an angle with respect to a radial line drawn from the center of the resistive path arc. The resistor card also has an arc-shaped continuously solid conductor base and a second set of spaced apart conductor lines extending from the base at an angle with respect to a radial line drawn from the center of the arc-shaped conductor base. The system includes a wiper assembly having a pair of spaced apart arms. Each arm has a plurality of parallel fingers extending from one end.

Abstract: A wave transmission line terminator having application in computer data buss termination, single and multiple channel analog transmission line termination and other similar terminations uses thick film components including resistors and capacitors in combination with a ball grid array termination. The thick film resistors are placed on a first side of a substrate opposite the capacitors and ball grid array, and are electrically connected thereto by electrically conductive vias in the substrate. Several different configurations are disclosed which make the terminator more suitable for specific application.

One of the fingers on a first arm engages a conductor line on the resistive path and a second finger on the first arm engages an adjacent conductor line along the resistive path.

Abstract: A ball grid array capacitor has a substrate with a top and bottom surface and a via extending through the substrate. Several capacitors are located on the bottom surface. The capacitors include a top electrode connected to the via, a dielectric layer connected to the top electrode, and a bottom electrode that is connected to the dielectric layer and a ball pad over the bottom electrode. A passivation layer is located between the capacitors. Several solder spheres are electrically and mechanically connected to the bottom electrode. A resistor can be mounted on the top surface and connected to the via to form a filter.

Abstract: A resistor network for terminating active electronic devices has low cross talk noise between the adjoining resistors and the conductors that connect the resistors to other electronic packages. A substrate has a top and a bottom surface. Resistors are located on the top surface. Conductors are also located on the top surface and are electrically connected to each end of the resistors. Vias extend through the substrate and electrically connect to the conductors. Solder spheres are positioned on the bottom surface and are electrically connected to the vias. An end of each of the resistors is electrically connected in common through a common conductor. The commoned resistors are electrically connected to a common via through the common conductor. The resistor network minimizes cross talk noise between the resistors and provides a high density interconnection.
