Abstract:
Shaped integrated passive devices and corresponding methodologies relate to construction and mounting of shaped passive devices on substrates so as to provide both mechanical and electrical connection. Certain components and component assemblies are associated with the implementation of surface mountable devices. Specially shaped integrated passive device are capable of providing simplified mounting on and simultaneous connection to selected electrical pathways on a printed circuit board or other mounting substrate. Shaped, plated side filter devices have plated sides which provide both mounting and grounding/power coupling functions. Thin film filters may be constructed on silicon wafers, which are then diced from the top surface with an angular dicing saw to produce a shaped groove in the top surface. The groove may be v-shaped or other shape, and is then plated with a conductive material. Individual pieces are separated by grinding the back surface of the wafer down to where the grooves are intercepted. The plated grooves serve as ground or power connection points for the filter circuit. The metallized slopes of the plated grooves are used in securing the individual pieces to a mounting surface, by soldering or using conductive epoxy.
Abstract:
A semiconductor component including: a substrate, at least one semiconductor chip arranged on the substrate and at least one passive device likewise arranged on the substrate. The passive device is mounted with its underside on the substrate. The semiconductor component further includes an interspace disposed between the underside of the passive device and the substrate. The interspace is filled with an underfilling material. In order to avoid the solder pumping effect, the upper side and the lateral sides of the passive device are also embedded in a plastic compound.

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 low-EMI circuit which realizes a high mounting density by converting the potential fluctuation off a power supply layer with respect to a ground layer which occurs on switching an IC device etc., into Joule's heat in the substrate without using any parts as a countermeasure against the EMI. Its structure, a circuit board using it, and a method of manufacturing the circuit board are also disclosed. Parallel plate lines in which the Q-value of the stray capacitance between solid layers viewed from the power supply layer and ground layer is equivalently reduced and which are matchedly terminated by forming a structure in which a resistor (resistor layer) and another ground layer are provided in addition to the power supply layer and the ground layer on a multilayered circuit board. A closed shield structure is also disclosed. This invention can remarkably suppress unwanted radiation by absorbing the potential fluctuation (resonance) which occurs in a power supply loop by equivalently reducing the Q-value of the stray capacitance, absorbing the standing wave by the parallel plate lines matchedly terminated and, closing and shielding the parallel plate lines.
