Abstract:
An electronic device packaging structure is described wherein an electronic device is electrically connected to a substrate wherein the electronic device subtends a non-normal angle with respect to the substrate. In a more specific embodiment, a plurality of electronic devices are stacked at offset with respect to each other to expose contact locations on the surface of each electronic device at an edge of each electronic device to form a stepped surface exposing a plurality of electronic device contact locations. This surface is disposed against a substrate having a plurality of contact locations thereon. The electronic device contact locations can be electrically interconnected to the substrate contact locations by solder mounds or alternatively by a cylindrical shaped elastomeric body having metallization bands with a spacing corresponding to the electronic device contact locations. The elastomeric body is pressed between the edge of the stacked electronic devices having the contact locations thereon and substrate surface to form electrical interconnections between electronic device contact locations and substrate contact locations through the electrically conducting bands. The stacked electronic devices can be thermally connected to a heat dissipation member. The stacked electronic devices can have a stepped surface embodying an enhanced area for transfer of heat from the electronic device stack to the heat dissipation member.
Abstract:
In an SIP type module of the type wherein memory ICs are mounted to both surfaces of a substrate, the present invention provides a face package type memory module wherein packaging is made in an inclined direction in place of vertical packaging of the prior art technique and only the memory ICs mounted to the upper surface side of the substrate are deviated to the position closer to the end portion of the substrate in order to drastically reduce the packaging height.
Abstract:
A bus assembly for a microcomputer comprising a motherboard having a data bus of the standard type, which bus assembly comprises means for mounting a plurality of daughtercards at an acute angle with respect to the motherboard. The bus assembly further comprises a bus extension card adapted to plug into the edge card connectors of the motherboard data bus so as to be retained parallel to the motherboard. The bus extension card is provided with a plurality of edge card connectors disposed at an acute angle with respect to the card and thus at an acute angle with respect to the motherboard.
Abstract:
A mounting arrangement is provided whereby an electronic display device with contact pins accessible on one side is mounted on a printed circuit board by means of a plurality of elongated pin extender elements connected between individual ones of the contact pins and points of contact on associated ones of the conductive leads on the printed circuit board, the elements having pin receiving means for receiving the pins and being oriented at an off-orthogonal angle with respect to said printed circuit board and the pin extender elements form a triangulated structural support for the display device.
Abstract:
In a small hand-held calculator the electroluminescent display is in the form of a series of light emitting diodes (''''chips'''') which are received on a printed circuit board. The electric signal output of the calculator circuit is communicated to the display through a series of pins which are stake mounted on a printed circuit board and the projected ends of these pins serve the dual purpose of communicating electric signals which determine the display and also serve to mount the printed circuit board of the display and its associated components. The pins are inclined so that the display can be disposed at whatever viewing angle is desired. Thus, although the small calculator may lie flat on a desk or other support surface, the plane of the display is disposed at an angle making viewing much more convenient, that is, at an angle approaching perpendicularity to the line of vision of the viewer. By utilizing the pins both as electrical signal communicating means as well as mounting means it is possible to locate the display at whatever angle is desired and in a much more convenient and economical manner.
