Abstract:
An embedded type multifunctional integrated structure and a method for manufacturing the same are disclosed. The present invention utilizes the concept of multi-layer design to integrated more than two passive components on a component structure that would be adhered to a substrate. Hence, the embedded type multifunctional integrated structure has an OCP function, an OVP function, an anti-EMI function, and an anti-ESD function at the same time. Therefore, the present invention effectively integrated two or more than one passive components in order to increase function of the embedded type multifunctional integrated structure. Moreover, the present invention effectively reduces the size of the passive components on a PCB and reduces the number of solder joints.

The present invention provides a surface mount composite electronic component which can be made compact. The structure of the surface mount composite electronic component is one in which a circuit element is formed on each of a set of opposing surfaces of an insulating substrate composed of a hexahedron, with electrodes that make up the circuit elements also functioning as external terminals. For example, a pair of first electrodes disposed on both ends of a front surface of the insulating substrate composed of a hexahedron, a pair of second electrodes disposed on a rear surface of the insulating substrate opposite the first electrodes, a first resistor disposed so as to contact both of the first pair of electrodes, and a second resistor disposed so as to contact both of the second electrodes.
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 fixed resistor network has an insulating substrate, a plurality of film resistors arranged on a top surface of the insulating substrate, terminal electrodes formed for the film resistors on each lengthwise sidewall of the insulating substrate at a given pitch along the sidewall, and recesses provided between the terminal electrodes. The occurrence of solder bridges between the terminal electrodes during solder mounting and the occurrence of chipping in the terminal-electrode-forming areas between the recesses on the lengthwise sidewall are both reduced by making the width of the recesses along the lengthwise sidewall either 0.44 to 0.48 times or 0.525 to 0.625 times the pitch.

Abstract:
When an electrode component is inserted into a through hole from one side and then rotated, parts of a conductive film are cut by a cutting blade. Another electrode component including a chip component whose one terminal is connected to an electrode of this electrode component is inserted into the through hole from the other side. When compression bonding is applied to the both electrode components so as to be joined together, an electrode of the former electrode component and the electrode of the latter electrode component are spread within the through hole with the pressure. The spread electrode of the former electrode component contacts a portion of the conductive film that is electrically connected to a front surface wiring, and the spread electrode of the latter electrode component contacts another portion of the conductive film that is electrically connected to a back surface wiring.
