Abstract:
The present invention relates to a microwave signal transition component (1) having a first signal conductor side (2) and a second signal conductor side (3). The signal transition component (1) is arranged for transfer of microwave signals from the first signal conductor side (2) to the second signal conductor side (3). The transfer component (1) comprises at least one, at least partly circumferentially running, electrically conducting frame (4), a dielectric filling (5) positioned at least partly within said conducting frame (4), at least one filling aperture (6; 6a, 6b) miming through the dielectric filling, and, for each filling aperture (6; 6a, 6b), an electrically conducting connection (7; 7a, 7b) that at least partly is positioned within said filling aperture (6; 6a, 6b). The present invention also relates to a method for manufacturing a microwave signal transition component according to the above.
Abstract:
A capacitor holder comprises: a holding portion made of a resin to have a cylindrical inner wall surface, at least an outer peripheral portion of the inner wall surface being open, the holding portion being configured to hold a capacitor inserted through the opening into an inside of the inner wall surface while elastically deforming the resin; a fixed portion formed of the resin integrally with the holding portion and positioned opposite to the opening of the holding portion; a pair of fitting grooves formed at a pair of end surfaces of the fixed portion opposed to each other adjacent to the holding portion, the fitting grooves being configured to fittably engage with end edges of a printed circuit board to extend along a surface of the printed circuit board; and a proximity suppressor formed of the resin as a part of the fixed portion and configured to suppress portions of the fixed portion where the fitting grooves are formed from being brought into proximity each other.

The housing has a mounting surface and the electronic apparatus is mounted to an object at the mounting surface , The large electronic components are arranged in a three-dimensional manner with respect to the mounting surface in such a manner that at least one of the large electronic components overlaps at least one of the large electronic components in a direction toward the mounting surface ,
Abstract:
To provide a mounting substrate that requires a reduced amount of solder and reduces a thermal effect of solder on the interior of an electronic component, and a microphone to be mounted on the substrate. A mounting substrate according to the present invention includes: a solder part formed on a part of an electrode formed on the mounting substrate; a resist film formed to prevent the solder of the solder part from flowing out of a predetermined range; and a gas-escape groove that is constituted by the absence of the electrode and the resist film and allows gas produced during soldering to escape. In the case where a component having a central terminal and a peripheral terminal is mounted on the mounting substrate, each part of the mounting substrate has the characteristics described below. That is, the electrode formed on the mounting substrate includes a central electrode part that faces the central terminal, a plurality of outer electrode parts that face part of the peripheral terminal, and a linkage electrode part that interconnects the outer electrode parts. The solder part is formed on each of the central electrode part and the outer electrode parts. The gas-escape groove is configured to allow the gas inside the peripheral terminal to escape to the outside.

Abstract:
Die Erfindung betrifft ein Verfahren zur Herstellung einer elektrisch leitenden Verbindung bei T-förmigen oder L-förmigen Leiterplattenkonfiguration mit mindestens zwei rechtwinklig aufeinander stehenden Leiterplatten (4, 5). Eine hohe Packungsdichte elektronischer Bauelemente auf den Leiterplatten (4, 5) wird dadurch erreicht, dass in dem Winkelbereich zwischen den beiden Leiterplatten (4, 5) MELF (Metal Electro-de Face)-Connectoren (1) eingelötet werden, deren Metallkappen (3) jeweils mittels winkelförmig angeordneter Lötpads (6) beide Leiterplatten (4, 5) kontaktieren.
Abstract:
A fuse holder component (1) includes a bottom plate (11) fixed to a printed board, and first and second side plates (12,13) whose main body portions individually extend from side edges of the bottom plate (11). The second side plate includes a suction portion (13e) extending through an extension portion from the main body portion and provided with a suction surface (13f) to which a suction nozzle of a mounter is accessible. A pair of fuse holder components, surface-mounted on the printed board by using the mounter, constitute a fuse holder that stably holds a glass-tube fuse.
