Abstract:
Apparatuses and processes associated with a dual in-line memory module (DIMM) adaptor card. Specifically, the DIMM adaptor card may be configured to removeably couple with a slot of a printed circuit board (PCB). The DIMM adaptor card may further be configured to removeably couple with a first DIMM and a second DIMM. Other embodiments may be described and/or claimed.
Abstract:
Systems, apparatuses, and methods may include a circuit board having a plated through hole with a via portion and a stub portion and a self-coupled inductor electrically coupled to the via portion of the plated through hole. The self-coupled inductor may include a first inductor mutually coupled to a second inductor in series to reduce a capacitive effect of the stub portion of the plated through hole.
Abstract:
In one embodiment, the apparatus comprises: a substrate having a first side and a second side, the second side being on an opposite side of the substrate from the first side, where the substrate has a first location on the first side at which an semiconductor package is to be coupled; and a cable coupled to the substrate on the second side of the substrate at a second location on the second side, the second location being at least partially below the first location.
Abstract:
An apparatus comprises a crosstalk cancelation circuit comprising a plurality of taps to output signals based on a signal transmitted via a first data line; and a summation circuit to combine a signal received by a second data line with the signals output by the plurality of taps to reduce near-end crosstalk present in the signal received by the second data line.
Abstract:
Techniques and mechanisms for facilitating connection between a packaged device and a substrate of another device. In an embodiment, a device—such as a printed circuit board—comprises a substrate and a hardware interface at a first side of the substrate, the hardware interface to couple the device to a package including integrated circuitry. The device is further configured to couple to a bridge device via contacts disposed at a second side of the substrate. An interconnect extends from the hardware interface to one of the contacts at the second side. In another embodiment, coupling the substrate to the bridge device interconnects two of the contacts at the second side to one another via the bridge device, where one or more contacts of the hardware interface (e.g., only a subset of all such contacts) are also interconnected with the bridge device via the second side.
Abstract:
Apparatuses and methods associated with shield lines, and/or complementary decoupling capacitors and/or electromagnetic absorbing materials are disclosed herein. In embodiments, an apparatus may include a substrate having a ground plane; and a first and a second transmission line disposed on the substrate. Further, the apparatus may include a shield line constituted with electromagnetic absorbing material disposed between the first and second transmission lines and not coupled with the ground plane. In embodiments, the substrate may further include a power plane having a plurality of edges and a plurality of spacing; a plurality of decoupling capacitors disposed on the power or ground plane; and electromagnetic absorbing materials adhered to the plurality of edges and disposed in the plurality of spacing. Other embodiments may be described and/or claimed.
Abstract:
Embodiments of the present disclosure are directed toward techniques and configurations for electrical signal absorption in an interconnect disposed in a printed circuit board (PCB) assembly. In one instance, a PCB assembly may comprise a substrate, and an interconnect formed in the substrate to route an electrical signal within the PCB. The interconnect may be coupled with a connecting component that is disposed on a surface of the PCB. An absorbing material may be disposed on the PCB to be in direct contact with at least a portion of the connecting component to at least partially absorb a portion of the electrical signal. Other embodiments may be described and/or claimed.

Abstract:
A two-part electrical connector includes a bottom connector and a top connector. The bottom connector includes a set of electrical contacts, at least one of which has a relatively short effective electrical stub length. The bottom connector may be mounted on a memory bus that also includes a standard memory receiver. In such a system, when driving by a memory bus, the bottom connector generates signal reflections that are significantly reduced compared to conventional systems.
