Abstract:
A low-profile passive-on-package is provided that includes a plurality of recesses that receive corresponding interconnects. Because of the receipt of the interconnects in the recesses, the passive-on-package has a height that is less than a sum of a thickness for the substrate and an interconnect height or diameter.
Abstract:
The invention relates to a conductor track unit, in particular for a motor vehicle. The conductor track unit is provided with conductor tracks which are embedded in an electrically insulating material. The conductor tracks are, in particular completely, surrounded by the electrically insulating material and are therefore not accessible from the outside. Electrical connections are electrically connected to the conductor tracks. The electrical connections are accessible from the outside, and therefore can be electrically connected to electrical contacts of electrical or electronic components such as a switch, detector, electronic radio component, integrated circuit, electronic chip, electronic control device or motor, for example by soldering. The conductor tracks and electrical connections are different components which are therefore initially independent of one another and can be produced independently of one another. A particularly robust yet delicate conductor track unit can be provided in this way.

Abstract:
The present invention relates to a method for manufacturing a heat-dissipating substrate for an LED and to a structure thereof. The method for manufacturing a heat-dissipating substrate for an LED, having a heat-dissipating fin, comprises: a first step of preparing a printed circuit board; a second step of forming an insertion hole for inserting the heat-dissipating fin at a specific portion of the printed circuit board; a third step of applying a cream solder to or forming a soldering material film on a portion of an upper surface of the printed circuit board extending from the insertion hole, an inner surface of the insertion hole, and/or a portion of a lower surface of the printed circuit board extending from the insertion hole; a fourth step of inserting the heat-dissipating fin into the insertion hole such that at least a portion of the heat-dissipating fin contacts the portion at which the cream solder is applied or contacts the soldering material film; and a fifth step of heating the heat-dissipating fin to solder a portion of the contact area between the heat-dissipating fin and the printed circuit board. According to the present invention, the sealed contact between the heat-dissipating fin and the printed circuit board is ensured, and the printed circuit board is protected from moisture or gas.
Abstract:
An assembly of at least two printed circuit boards includes an intermediate connection layer (40) for providing electrical and mechanical connections between first and second circuit boards (10,12). The intermediate connection layer comprises a lower set of connection pads connecting the intermediate layer to the first circuit board, and an upper set of connection pads connecting the intermediate layer to the second circuit board. The intermediate connection layer comprises connection regions and a void region, wherein the void region extends between the first and second circuit boards and houses electronic components (16) of the circuit boards. This arrangement uses an intermediate connection layer to provide a stable mechanical connection, provide electrical connections between the circuit boards, and define a spacing for housing the electrical components of one or both of the circuit boards. The connections can be soldered, and this can be performed by reflow soldering methods, and using pick and place equipment.
Abstract:
Multiple small conductive and flexible hollow rings (10), each of which is made from a pliable material, provide a flexible connection medium for use between a substrate (8) and a microelectronic device package (4). Each ring is soldered to both the substrate and the device. A portion (20, 22) of the sidewall of each ring is not soldered thus insuring that at least part of the ring stays flexible. The rings accommodate elevation differences on a substrate and electronic device package. They also provide a vibration resistant and flexible joint.
Abstract:
Materials which are used for detachable injection moulded parts can be applied for making fast, solid and reliable connections, particularly by using easily degradable respectively soluble polymers. The materials can be adapted to other conditions, such as the prevention of chemical influencing or other kind of poisoning, the degree of electrical insulation, etc.
