    Abstract: A ball grid array package that can be readily tested before or after mounting to a printed circuit board. The ball grid array includes a substrate having a top surface and a bottom surface. Several conductive pads are located on the top surface. Several passive circuit elements are located on the top surface between the conductive pads. An insulative coating is placed on top of the passive circuit elements and the substrate. The insulative coating has openings over the conductive pads. The openings are adapted to be accessible by an electrical probe. Conductive vias extend through the substrate between the top and bottom surfaces. The vias electrically connect with the conductive pad on the top surface. Several conductive balls are located on the bottom surface. Each conductive ball is electrically connected to one of the vias.

    Abstract: A high frequency module is provided with a resistor array layer with interconnections, in which a plurality of resistor elements having a prescribed resistance value are formed as an array, and in which an interconnection pattern for providing electrical connection to each resistor element is formed in advance. Additionally, a capacitor array layer with interconnection in which a plurality of capacitor elements having a prescribed capacitance value are formed as an array and an interconnection pattern for providing electrical connection to each capacitor element is also formed in advance for later use. A desired circuit constant is obtained by providing interconnections among the plurality of resistor elements and among the plurality of capacitor elements, respectively, in any given combination by simply modifying the respective interconnection patterns instead of the entire module. With this configuration, a high frequency module of a more compact and lighter type which facilitates design modification is provided at a low cost.

    Abstract: A thin-film metal resistor (44) suitable for a multilayer printed circuit board (12), and a method for its fabrication. The resistor (44) generally has a multilayer construction, with the individual layers (34, 38) of the resistor (44) being self-aligned with each other so that a negative mutual inductance is produced that very nearly cancels out the self-inductance of each resistor layer (34, 38). As a result, the resistor (44) has a very low net parasitic inductance. In addition, the multilayer construction of the resistor (44) reduces the area of the circuit board (12) required to accommodate the resistor (44), and as a result reduces the problem of parasitic interactions with other circuit elements on other layers of the circuit board (12).
