摘要: Techniques pertaining to powering multiple platforms with a minimum impact on air passage in a predefined environment are disclosed. Instead of connecting each of the platforms in a chassis to a power supply therein, embodiments of the present invention uses what is referred to as cascading powering to power all platforms within minimum cable delivery. According to one embodiment of the present invention, a motherboard is disposed between two power supply units that are used to power the motherboard. The motherboard has power connectors located towards or near the power supply units so that only short cables are needed to power the platform.

摘要: A method and associated apparatus are disclosed for forming a conductive via that extends partly through a multi-layer assembly, wherein the method comprises forming a cavity from a surface of the multi-layer assembly to a first depth. The cavity extends through a plurality of layers of the multi-layer assembly. The plurality of layers comprises a healing layer comprising a plurality of microcapsules. Forming the cavity ruptures some of the plurality of microcapsules to release encapsulated material into the cavity. The released encapsulated material defines a second depth from the surface, the second depth being closer to the surface than the first depth. The method further comprises depositing conductive material within the cavity to form the conductive via that extends to the second depth.

摘要: The embodiments herein relate to an apparatus and medium for selective partitioning of a via in a printed circuit board as to produce an electrically isolating portion between two electrically conducting portions in said via. The apparatus and medium implement a step of prior to drilling the hole for the via, laminating plating resist layers to the printed circuit board at a distance from each other corresponding to a desired length of the electrically isolated portion of the via. After drilling, copper is added to selected portions of the interior of the via in two different processing steps followed by a step of removing undesired copper as to produce the electrically isolating portion.

摘要: A multilayer PCB having may include a first sub-composite core having a first core structure sandwiched between a first conductive layer and a second conductive layer, the first core structure including one or more dielectric and conductive layers. A first via hole extends at least partially through the first core structure, wherein an inner surface of the first via hole is plated with a conductive material along a first via segment electrically coupling the first conductive layer to an internal layer or trace within the first core structure. A second via segment extending between the second conductive layer and the internal layer or trace is devoid of the conductive material such that the first via hole is substantially stub free. A first dielectric layer is coupled to the second conductive layer. A second sub-composite core coupled to the first dielectric layer.

摘要: A printed circuit board includes a first trace, a second trace, and a first via. The first trace is in a first conductive layer. The second trace is in a second conductive layer. The first via interconnects the first trace and the second trace, and communicates a first signal from the first trace to the second trace through a third conductive layer. The third conductive layer has a higher impedance than the first conductive layer and the second conductive layer.
