Abstract:
PROBLEM TO BE SOLVED: To provide a method of fabricating a vertically mountable integrated circuit (IC) package. SOLUTION: The method is provided for fabricating the vertically mountable integrated circuit (IC). The integrated circuit is mounted on a printed circuit board (PCB) and is electrically connected to bond pads on the PCB. The bond pads are connected to vias embedded in the PCB. The IC, bond pads, vias, and PCB are partially divided to form the vertically mountable IC package. When divided, the vias are cut across to be partially exposed, so that a mountable area is provided for the IC package. The IC package is sealed or stored in a dielectric material. Further, the vias are treated with a preservative for preventing oxidation and improving solderability or other suitable deposits of electroless metal plating. COPYRIGHT: (C)2007,JPO&INPIT
Abstract:
Two flat packages (110, 111) are arranged to achieve a mirrored footprint by employing guides (100), which are positioned within a mounting aperture a printed circuit board. The flat packages include leads (120,121) which extend from the edge of the flat package. A semiconductor chip is encapsulated by the flat packages.
Abstract:
A flat package (10) for semiconductor integrated circuit devices allows edge-mounting and surface-mount. The package may be molded plastic (12) containing a semiconductor chip (11), and flat leads (14) extend from one edge of the package. The leads are bent to provide an area (18) to solder to conductors on a PC board. Mechanical positioning, mechanical support and spacing are provided by studs (15) extending from the edge of the package adjacent the leads. The studs have stops (17) formed at a position even with flat outer surfaces of the bent leads; the portion outward of the stops fits into holes in the PC board.
Abstract:
A method of fabricating a vertically mountable integrated circuit (IC) package is presented. An integrated circuit is mounted on a printed circuit board (PCB) and electrically coupled to a bond pad on the PCB. The bond pad is coupled with a via that is embedded in the PCB. A portion of the PCB comprising the IC, the bond pad and the via is separated in order to create a vertically mountable IC package. The via is cut through cross-sectionally during singulation so as to expose a portion of the via and thereby provide a mountable area for the IC package. The IC package may be encapsulated or housed in a dielectric material. In addition, the via may be treated with a preservative or other suitable electroless metal plating deposition that prevents oxidation and promotes solderability.

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.
