Abstract:
A radial lead type electronic component (4) includes a couple of plate-type lead terminals (1,2,3) projecting from a protective resin member (9) in the same direction. These lead terminals (1,2,3) are provided with inclined edges (1d,1e;2d,2e), which make the body portions (1c-3c) gradually narrowed toward leg portions (1a-3a), in leg-side edges of body portions. Among inclined edges, inclinations ϑ ₁ of the outer ones with respect to the leg-projecting direction are greater than inclinations ϑ ₂ of the inner ones with respect to the same direction.
Abstract:
This package for integrated devices, to be fixed on supporting plates, in particular on printed circuits, comprises contact pins (5a,5b) to be inserted in holes (2) of the supporting plates (1) and to be soldered thereto. To prevent overturning of the package, which may lead to short circuits among the components, at least some (5a) of the contact pins are provided with protruding portions (10) defining abutments cooperating with the supporting plate to limit the inclination of the package with respect to the plate.
Abstract:
A heat radiating structure for a pin type power LED is provided to effectively release the heat generated through the first lead frame connected to the LED device by setting up the radiating unit in the space between a molding unit of substrate and the LED. An LED device(1) is settled on the settling portion extended to the first lead frame. The LED device supplies the power through a lead from the outside. A stopper(4) is formed at one end of leads(5,5') of two lead frames(7,6). A radiating unit(10) is installed in the formed space between a molding unit(8) and a substrate(3) of LED. The radiating unit delivers the heat generated from the LED device to the lead of the first lead frame. The delivered heat is delivered to the radiating unit contacted with the lead.
Abstract:
PURPOSE: A pin connection is provided which requires no solder or soldering process by coating a polymer thick film across the top surface and inner front surface of a substrate, and pressure fitting a pin whose diameter is smaller than that of a hole into the polymer thick film across the inner front surface. CONSTITUTION: Related to a double-sided printed circuit board arrangement, a polymer thick film (30), for example, is coated across the top surface and the bottom substrate of a substrate (10), and further, the polymer thick film (30) is coated across an inner front surface (20) which forms a hole. A pin (40) whose diameter is smaller than that of the hole is pressure fitted into the whole while contacting the polymer thick film (30). The pin (40) is preferred to be held in the hole by pressure-fitting and/or mechanical connection. This configuration requires no solder or soldering process for pin connection.
Abstract:
The printed circuit board includes a number of non-through holes formed in the thickness direction. Throughholes are formed in selected non-through holes. Conductive lands are formed on the periphery of the openings of the non-through holes. A second set of conductive lands are formed on the periphery of the openings of the through holes on the opposite surface and having a smaller outside diameter than the other lands. Conductors formed on the inside wall of the non-through holes and the through holes connect the conductive lands in one surface with the conductive lands in the opposite surface.
