    Abstract: A backplane assembly includes a main backplane having a first power conductor, a backplane strip having a second power conductor, and connecting members disposed between the main backplane and the backplane strip. The connecting members hold the backplane strip in a fixed position relative to the main backplane and electrically connect the first power conductor and the second power conductor. In one arrangement, the connecting members include source standoffs which extend from a source area of the main backplane to the backplane strip, and target standoffs which extend from a target area of the main backplane to the backplane strip. The source and target standoffs and the second power conductor provide a current path which increases current carrying capacity from the source area to the target area above that provided by the first power conductor alone. Thus, the backplane assembly is well-provisioned for distributing high currents to circuit boards.

    Abstract: The present invention is a reconfigurable substrate which includes at least one signal line layer stack. Each signal line layer stack is defined to include two substantially parallel insulating layers and a signal line layer interposed between the two insulating layers and substantially parallel to the insulating layers. The substrate includes at least one conductive isolation layer adjacent to at least one signal line layer stack and substantially parallel to the at least one signal line layer stack. The substrate is reconfigurable to different performance levels by adding or removing at least one conductive isolation layer.

    Abstract: In a multi-layer printed-wiring board (100) the ground and power conductor-bearing layers (102 and 103) are placed immediately (without intermediancy of other conductive layers) below the outer surface conductor-bearing layers (101) and are connected to the outer surface layers by micro-vias (110 and 111) that do not extend beyond the ground and power layers, whereby the micro-vias avoid causing trace-routing blockages on lower, signal-routing, layers (104). The surface layers define traces for static and infrequently-changing signals. One or both of the ground and power layers define double pads (203) each comprising a pair of normal pads (204-205) interconnected by a short trace (206). One single pad of each pair is connected by a micro-via to a corresponding pad (202) on an outer surface layer, which also typically has a lead (201) of a component (200) soldered thereto or serves as a testpad. The other single pad of each pair is connected by a buried through-hole via (207) to pads (208) on the lower, signal-routing, layers. This removes the double pads from the outer surface layer and thus reduces trace-routing blockages on the outer surface layer, and at the same time solves the problem of connecting micro-vias to through-hole vias.

    Abstract translation: 在多层印刷电路板(100)中,地面和电力导体承载层(102和103)被立即(没有其他导电层的介入)放置在外表面导体承载层(101)下方并被连接 通过不延伸超过接地层和功率层的微通孔(110和111)到外表面层,由此微通孔避免在较低信号路由层(104)上引起轨迹路由阻塞。 表面层为静态和不频繁变化的信号定义轨迹。 接地层和功率层中的一个或两个限定双重衬垫(203),每个衬垫包括通过短迹(206)互连的一对正常焊盘(204-205)。 每对的一个单个焊盘通过微通孔连接到外表面层上的相应的焊盘(202),外表面层通常还具有焊接到其上的部件(200)的引线(201)或用作测试板。 每对的另一个单个焊盘通过埋入通孔(207)连接到较低信号路由层上的焊盘(208)。 这从外表面层去除双垫,从而减少外表面层上的迹线路由阻塞,同时解决了将微通孔连接到通孔通孔的问题。
