Abstract: A press-fit terminal is configured to exert a reaction force through elastic deformation on a through-hole and to be supported by the board, and includes two beams to be opposite to each other and to be elastically deformable. The two beams respectively have counter surfaces facing to each other. Each beam includes: a base material with a main surface and a side surface having one or more rounded corners formed in a curved surface with a contact zone in contact with the wall surface of the through-hole; and a plated film having a main portion on the main surface and an extension portion having an average thickness smaller than an average thickness of the main portion. The two beams have two or more of the rounded corners in total, and at least one of the rounded corners are provided with the extension portion.

Abstract: A lubricant composition comprises a perfluoropolyether oil and an adhesive component.

Abstract: There is provided a press-fit lubricant composition comprising an unsaturated compound with an iodine value of 100 or more.

Abstract: An electronic device includes a press-fit terminal, an electronic component and a substrate. The substrate includes a first through hole, a second through hole and an inlay. The press-fit terminal is press-fitted in the first through hole. The second through hole is located between the first through hole and a part of the substrate at which the electronic component is mounted. The inlay is made of a metal material and press-fitted in the second through hole. The inlay restricts a strain in the substrate and restricts decrease of a holding force of the substrate holding the press-fit terminal.

Abstract: A circuit board has a through hole extending from a front surface to a rear surface. A press-fit terminal is press-fitted from the front surface into the through hole and is connected to a land, which is formed on a wall surface of the through hole. A support member supports the rear surface of the circuit board when the press-fit terminal is press-fitted into the through hole. A housing has a bottom portion and an opening, which is on the opposite side of the bottom portion. The circuit board is affixed to the housing to cover both the opening and the support member. The support member is held and interposed between the rear surface and an inner surface of the bottom portion.

Abstract: The present invention is a flux for soldering, containing a base resin and an activating agent, in which the base resin contains a thermoplastic acrylic resin obtained by polymerizing a monomer component containing a long chain alkyl(meth)acrylate, the long chain alkyl moiety of the long chain alkyl(meth)acrylate has a branched structure having 12 to 23 carbon atoms, and the acrylic resin has a weight average molecular weight of 30000 or less. A solder paste composition of the present invention improves wettability, storage stability and crack resistance in residue portions, and printability for fine portions without adhering to a squeegee when printed.

Abstract: A soldering flux contains a base resin and an activating agent. The soldering flux contains, as the activating agent, an oxygen-containing heterocyclic compound having at least one carboxyl group in a molecule. A solder paste composition contains the abovementioned soldering flux and the solder alloy powder. These enable exhibition of excellent wettability to lead-free metals and plating, irrespective of the type of the metals.
