Abstract:
The present invention is to provide a printed wiring board which can certainly prevent damage of conductive pattern caused by the terminal. The printed wiring board has a board, a conductive pattern, a through-hole and a non-conductive area. A lead wire of resistance mounted on the printed wiring board is inserted into the through-hole 4. The lead wire projects from a surface of the board, and is bent close to the surface. The non-conductive area is formed into a fan-shaped shape enlarging toward a tip of the lead wire from a center of the through-hole. Since the bent lead wire is arranged on the non-conductive area, the non-conductive area can prevent damage of the conductive pattern which is caused by touching the lead wire to the conductive pattern.

[Object] An electronic component on-substrate mounting structure capable of mounting an electronic component having a round external shape on a substrate in a predetermined attitude and keeping an allowance of a lead to a predetermined value is provided. [Means for Settlement] A lead 12 of an electronic component 11 is inserted into a lead hole 31 of a substrate 30, thereby mounting the electronic component 11 on the substrate 30. The lead 12 includes a base part 16 extending from an electronic component main body 13, a support part 17 bent from the base part 16, abutting an electronic-component mount surface 30A of the substrate 30 at a predetermined length, and supporting the electronic component main body 13, and an insertion part 18 bent from the support part 17 and inserted into a lead hole 31 of the substrate 30.

Abstract:
A supporting component (1) adapted for being mounted on a substrate (11) and for serving as a support for a surface mounted device (15) comprises a body (2) having a first surface (3) adapted for being mounted on the substrate (11), and a second surface (4) being adapted for supporting the surface mounted device (15). The second surface (4) is inclined in relation to the first surface (3). The supporting component (1) further comprises a first supporting component conductor (6) adapted for forming an electrical contact between a first substrate conductor (12) of the substrate (11) and a first electrode (16) of the surface mounted device (15). In a method of mounting a surface mounted device (15) in an inclined manner on a substrate (11) the supporting component (1) is mounted on the substrate (11) with the surface mounted device (15) on top of it.
Abstract:
A three-dimensional wiring body for mounted with an electronic component in which a flat wiring body mounted with a large number of electronic components is bend previously to be suited to the shape of a base structure where the flat wiring body is disposed and formed as a three-dimensional flat wiring body. An electronic component mounting structure where the three-dimensional wiring body for mounting an electronic component is mounted on a base structure formed three-dimensionally using a plurality of base members and coupling members is also provided. An electronic component is connected electrically and mechanically with the flat wiring body through a connector composed of a back plate portion and a piercing piece.
Abstract:
A submount for arranging electronic components on a substrate is provided. The submount comprises a head member and at least one substrate-engaging member protruding from the head member. The head member comprises at least two, from each other isolated, electrically conductive portions, where each electrically conductive portion comprises a component contact, adapted for connection of electronic components thereto, and a substrate contact on arranged on said substrate side, adapted for bringing said electrically conductive portions in contact with a circuitry comprised in said substrate. The submount of the present invention may be used to attach electronic components, such as light-emitting diodes, to a textile substrate, without the need for soldering the electronic component directly on the substrate.
Abstract:
To improve electronic part packaging efficiency without sacrificing the transmission distance of a radio IC tag, a recess is formed in the front side surface of a printed wiring board. An IC chip is placed in the recess so that the IC chip does not protrude from the front side surface, a first major surface la and a second major surface of the printed wiring board. Antenna elements of an antenna are formed on the front side surface on the opposite sides, respectively, of the IC chip, and the antenna is connected to the IC chip. The antenna is a dipole antenna of a length equal to half the wavelength of radio waves to be radiated by the antenna.

This invention relates to arranging components of an electric circuit within an apparatus while taking into consideration safety requirements especially due to IEC 60065. According to the present invention a faulty contact or interruption which can constitute a Potential Ignition Source is avoided by providing at least two separate solder pads (12,13;22,23;33,34,35,36) for at least the relevant one of the connection wires (11;21;31) of an electric component (diode 1;ceramic capacitor 2;transistor 3) to be inserted and soldered particularly on a printed circuit board (4).
Abstract:
The invention provides a mounting construction in which an electronic component is mounted on a flexible substrate. The mounting construction comprises a flexible substrate 10 including a flexible sheet 11, bendable electrode pattern forming portions 17 and 17 formed on the flexible sheet, and electrode patterns 13 and 13 formed on the electrode pattern forming portions, an electronic component 30 having electrode portions 33 and 33, and a clamping member 40 having clamping pieces 41 and 41 for clamping the electronic component 30 therebetween. The electrode pattern forming portions 17 and 17 are deflected, so as to cause the electrode patterns 13 and 13 to be contacted with the electrode portions 33 and 33 of the electronic component 30 placed on the flexible substrate 10. By this, the electronic component 30 is clamped by the clamping pieces 41 and 41 of the clamping member 40 through the deflected electrode pattern forming portions 17 and 17. Thus, the electronic component 30 may be easily and positively secured to the flexible substrate 10, without employing additional reinforcing means such as adhesives.
