A material board for producing a hybrid circuit board includes a plurality of hybrid circuit board sections 1 on each of which an electronic component 2 is mounted and a metallic terminal plate 3 for external connection is bonded so as to project from the hybrid circuit board section. A frame portion 6 is defined between the hybrid circuit board sections, and the hybrid circuit board sections are integrally connected to the frame portion via a thin strip 8 provided at an intermediate portion of grooves 7 each surrounding a respective one of the hybrid circuit board sections entirely. In bonding the terminal plate 3 to the hybrid circuit board by soldering, the terminal plate is temporarily bonded to the frame portion 6 with an adhesive 9. The adhesive is prevented from spreading toward the end of the terminal plate. A hole or a recess 10 is formed in the frame portion 6 at a region with which the terminal plate 3 is to overlap and which is closer to an end of the terminal plate than a portion to which the adhesive 9 for temporarily bonding the terminal plate to the frame portion is to be applied is.

An electronic circuit device includes a sub-board disposed upright on a main board. The sub-board is electrically coupled to the main board via a board terminal) disposed at sub-board edge. A semiconductor element is mounted on the sub-board facing the sub-board in parallel. A temperature sensor is also mounted on the sub-board. A heat sink is formed so as to surround the sub-board and the semiconductor element. A resin material is injected inside a heat sink so as to cover the sub-board, the temperature sensor, and the semiconductor element.
Abstract:
After respective one ends of lead wires are fixed to a printed circuit board, the lead wires are bent, the printed circuit board is brought into a case and the other ends of the lead wires are bonded to terminals of the case. Since the lead wires are processed before the substrate is brought into the case, this eliminates the necessity to perform formation of the bent portions of the lead wires and fixing of the lead wires to the substrate in a narrow space of the case and allows simplification of bonding operation. Thus provided is a lead wire bonding method for bonding lead wires with bent portions to the substrate, which simplifies a bonding operation.

Techniques for making robust but precise electrical components, such as molded equalizers designed for interface with amplifiers in CATV or other communications equipment, are disclosed. An exemplary embodiment of an electrical component includes an injection-molded housing encapsulating an equalizer circuit and with pins protruding from one end. The housing and pins are designed for interface with predetermined locations in CATV amplifiers or optic nodes. The addition of the molten plastic changes the performance of the equalizer circuit, requiring pre-mold adjustments to the circuit design to be made in order for the final molded equalizer to achieve the desired operating characteristics.
