A computing card for an information handling system, the computing card system including a computing card, including: a first side including: a first body surface, the first body surface including a first plurality of conductive pads configured to connect respectively with a first set of pins of a computing card receptacle; a first indented surface configured to connect with a second set of pins of the computing card receptacle; a first connecting surface defined between the first body surface and the first indented surface; a bottom surface; and a plurality of internal layers, wherein one or more of the internal layers are exposed at the first indented surface, and are connected to the bottom surface.

Computing card system with accessible internal layers and edge interconnects for an information handling system

Systems and methods that may be implemented to provide on-board trace impedance testing for a system level board of an information handling system. A printed circuit board (PCB) of the system level board may include built-in test trace circuitry that may be used to measure board trace impedance so that the trace impedance of a fully assembled system level board may be tested and verified for compliance with trace impedance specification, and without requiring any disassembly of the board.
