Abstract:
An electronic, in particular microelectronic, functional group and to a method for its production are described. The method can include the following steps: a) coating of a mount with a non-conductive adhesive; b) application of a conductor structure to a subarea of the adhesive layer; c) arrangement of an electronic component with at least one external electrical connecting contact on the adhesive layer and on the conductor structure, with the at least one connecting contact of the electronic component being brought directly into contact with the conductor structure, and with a part of the outer casing of the component being brought directly into contact with the adhesive layer. The method can allow electronic, in particular microelectronic, functional groups to be produced with care, quickly and in particular at low cost.
Abstract:
An exemplary rigid printed circuit board (PCB) includes a main portion, a supporting portion and a connecting portion. The supporting portion is for supporting electrical elements. The connecting portion includes two end portions and a main body therebetween. The main body is spaced from the main portion and the supporting portion. The two end portions are respectively connected to the main portion and the supporting portion. A PCB assembly and a PCB module using the same are also provided.
Abstract:
An electronic apparatus includes metal wiring plates placed together in the same plane to provide a wiring circuit, electronic devices mounted to the wiring plates through a solder, a case having a base portion and columnar portions extending from the base portion. The wiring plates are fixed to the columnar portions such that the wiring circuit is spaced from the base portion. The wiring plates have an enough thickness to resist a large current for operating the electronic devices and to release heat generated by the electronic devices. The wiring circuit is spaced from the base portion of the case so that the heat generated by the electronic devices is released in the space efficiently. The electronic devices are soldered to the wiring plates at once in a thermal reflow process.
Abstract:
A printed circuit board includes at least two conductive traces, each having a first portion and a second portion. The printed circuit board also includes a cross-over section that includes two electrically conductive portions, each connecting electrically to the first and second portions of a corresponding one of the conductive traces, such that the conductive traces in their first portions lie on opposite sides of each other as they do in their second portions.
Abstract:
A wiring substrate of a semiconductor component includes: an underside with a wiring structure; a top side with cutouts; a rubber-elastic material arranged in the cutouts; and external contact pads arranged on the rubber-elastic material and configured to be coupled to external contacts. A method for producing a wiring substrate of this type, involves pressing the rubber-elastic material pads into a precursor of a polymer plastic during the production process.

An illumination assembly includes a compliant substrate comprising a first and second electrically conductive foil separated by an electrically insulating layer. The insulating layer includes a polymer material loaded with particles that enhance thermal conductivity of the insulating layer. A plurality of LED dies are disposed on the first conductive foil.
Abstract:
A method is for making a non-planar three-dimensional (3D) multilayered circuit board. The method may include forming a stacked arrangement including at least one pair of liquid crystal polymer (LCP) layers with a bonding layer therebetween. The stacked arrangement may further include at least one electrically conductive pattern layer on at least one of the LCP layers. The method may further include heating and applying pressure to the stacked arrangement to shape the stacked arrangement into a non-planar 3D shape and concurrently causing the bonding layer to bond together the adjacent LCP layers of the stacked arrangement to thereby form the non-planar 3D multi-layered circuit board.
Abstract:
An object of the invention is to provide a connecting structure of circuit boards in which whether or not the circuit boards have been favorably connected can be more easily judged as compared with the prior art, even in case where connecting portions have been connected with pressure by arranging the connecting portions face to face, a connecting method of the circuit boards, and a compressing tool for connecting the circuit boards. A connecting structure 10 of circuit boards includes a first circuit board 11 and a second circuit board 12. A first connecting portion 17 of the first circuit board and a second connecting portion 21 of the second circuit board are arranged face to face interposing an adhesive 13, and clamped by a compressing tool 25 so that circuit patterns 16, 19 may be brought into contact with each other, whereby the first connecting portion 17 and the second connecting portion 21 will be connected with heat and pressure. In this connecting structure 10 of the circuit boards, a pair of unbonded parts 35 are formed in a compressing region 34 of a soft substrate 18 with which an upper compressing tool 26 is adapted to be contacted.
Abstract:
A flash-memory device has a printed-circuit board assembly (PCBA) with a PCB with a flash-memory chip and a controller chip. The controller chip includes an external Secure-Digital (SD) interface, and a processing unit to read blocks of data from the flash-memory chip. The PCBA is encased inside an upper case and a lower case, with SD contact pads on the PCB that fit through contact openings in the upper case. Dividers between openings in the upper case that expose the SD contact pads also support the PCB at a slanted angle to the centerline of the device. The PCB slants upward at the far end to allow more thickness for the chips mounted to the bottom surface of the PCB. A user-slidable switch may be slanted to compensate for the PCB slant. The PCB may have a flex section to facilitate the slant without a slanted switch.
Abstract:
A hybrid structure of multi-layer substrates comprises a first multi-layer substrate and a second multi-layer substrate. The first multi-layer substrate stacks up first metal layers, first dielectric layers alternately and has VIAs. A border district of a first metal layer connects with a border district of the corresponding first dielectric layer. The border districts are separated from adjacent first metal layers and adjacent first dielectric layers. The second multi-layer substrate stacks up second metal layers and second dielectric layers alternately. A border district of a second metal layer connects with a border district of the corresponding second dielectric layer. The border districts are separated from adjacent second metal layers and adjacent second dielectric layers. The VIAs are located at the border districts of the first dielectric layers and each VIA has electric conductor therein to connect one first metal layer with one second metal layer.
