A crimp terminal-equipped flexible printed circuit board includes: a first flexible printed circuit board having a base film and a circuit provided on a surface of the base film and made of metal foil; multiple crimp terminals including crimp pieces crimped to penetrate the first flexible printed circuit board and bent to bite into part of the circuit; and an insulating reinforcing film partially integrally provided on an area of the base film where the multiple crimp pieces penetrate.

A contacting plate is for creating an electrical connection to at least one component. The at least one component has a housing back, which is opposite the contacting plate. A method is for creating a contacting plate and the specification of options for electrical contacting between a component and contacting plate. An electrical contact and a mechanical fastening are formed between the contacting plate and the housing back of the at least one component.

A low noise relay includes a main body part provided with a terminal on a first surface thereof. A cover part is coupled to the terminal and the first surface of the main body part. The cover part is electrically connected to the terminal of the main body part. A vibration reduction part is connected and electrically coupled to the cover part. The vibration reduction part is configured to support the main body part to be suspended in air. A pin part is configured such that a first side of the pin part is connected with and electrically connected to the vibration reduction part.

A semiconductor guide pin is disclosed. Specific implementations may include a heatsink, one or more substrates coupled together, one or more pressfit pins coupled to the one or more substrates, and two or more guide pins coupled to the one or more substrates, where the two or more guide pins may have a height greater than the one or more pressfit pins.

A press-fit terminal includes a compliant part having a widened part including contact points that protrude to the outermost side along an orthogonal direction (first orthogonal direction Y) orthogonal to an insertion direction X with respect to a through hole of a board and a hole that allows deformation of the widened part toward an inside in the orthogonal direction, and is press-fitted into the through hole 23 along the insertion direction X to come into contact with an inner peripheral surface of the through hole of the board.

The area projections or a spacer occupies on the upper surface of a resin casing increases as the size of a power semiconductor module decreases, and therefore another means for defining a clearance between a control board and the resin casing is desired. A power semiconductor module is provided, including: a housing which houses a power semiconductor chip; and at least one control pin or guide pin which protrudes outward from an upper surface of the housing, wherein the at least one control pin or guide pin has at least one step in a height direction from the upper surface of the housing toward a tip farthest from the housing.

On a conductive plate of an insulated substrate, one open end of a main body part of a cylindrical contact member is bonded by solder. In a hollow part of a hollow cylinder shaped external electrode terminal, a part of the other open end side of the main body part of the cylindrical contact member is inserted from an open end of the external electrode terminal. The other end of the external electrode terminal is separated into branches by cuts inserted in a through-hole insertion part. A column surface of the outside of the branches of the external electrode terminal has an arc shape. Pressure in a direction from inside the external electrode terminal toward the outside is applied to the branches of the through-hole insertion part by an auxiliary wedge. With such a configuration, assembly defects accompanying connection of the external electrode terminal and other members may be eliminated.

A power semiconductor device includes: a circuit body having a pair of conductor parts and a power semiconductor element sandwiched between the pair of conductor parts; a substrate in which a through hole is formed; and a sealing material that seals at least a part of each of the circuit body and the substrate, in which the circuit body is inserted into the through hole and has first and second exposed surfaces exposed from the sealing material, and the substrate has, in the through hole, a first protrusion and a second protrusion that protrude toward a center of the through hole and are connected to the circuit body, the first protrusion and the second protrusion being formed at positions opposed to each other in the through hole, and at least one of the first protrusion and the second protrusion being a terminal that transmits power to the power semiconductor element.

A crimp terminal-equipped flexible printed circuit board includes: a first flexible printed circuit board having a base film and a circuit provided on a surface of the base film and made of metal foil; multiple crimp terminals including crimp pieces crimped to penetrate the first flexible printed circuit board and bent to bite into part of the circuit; and an insulating reinforcing film partially integrally provided on an area of the base film where the multiple crimp pieces penetrate.

A method of manufacturing a wiring board includes a stacking process in which N (N is an integer equal to or greater than 2) wiring layers, end portions of which include linear conductor patterns, are stacked, with the end portions superimposed, via substrates (insulating layers) provided among the wiring layers and a laminated plate is manufactured and a removing process in which the insulating layers around the end portions of the conductor patterns of the laminated plate are removed to machine the end portions into N flying leads projecting from an end face.
