Systems and methods for assembling daughter card to host card
An information handling system may include a motherboard and an information handling resource mechanically and electrically coupled to the motherboard. The information handling resource may include a circuit board, a connector mounted to a surface of the circuit board and configured to electrically couple to a corresponding connector mounted to a surface of a second circuit board of a second information handling resource, a first standoff extending from a surface of the circuit board, and a second standoff extending from the surface and arranged relative to the first standoff such that the first standoff and the second standoff are configured to mechanically engage with engagement features of the second information handling resource to define an axis of pivot between the circuit board and the second circuit board to align the connector to the corresponding connector.
1 . An information handling system comprising:
a motherboard; and
an information handling resource mechanically and electrically coupled to the motherboard and comprising:
a circuit board;
a connector mounted to a surface of the circuit board and configured to electrically couple to a corresponding connector mounted to a surface of a second circuit board of a second information handling resource;
a first standoff extending from a surface of the circuit board; and
a second standoff extending from the surface and arranged relative to the first standoff such that the first standoff and the second standoff are configured to mechanically engage with engagement features of the second information handling resource to define an axis of pivot between the circuit board and the second circuit board to align the connector to the corresponding connector.
2 . The information handling system of claim 1 , the information handling resource further comprising a threaded insert configured to mechanically couple to a captive screw maintained within the second circuit board.
3 . The information handling system of claim 1 , wherein at least one of the first standoff and the second standoff comprises:
a shaft extending from the surface of the circuit board;
a head coupled to the end of the shaft; and
a barrel formed around a portion of the shaft, such that the shaft includes an engagement region on a surface of the shaft located between the head and the barrel and configured to mechanically engage with an engagement feature of the second information handling resource to define the axis of pivot.
4 . The information handling system of claim 3 , wherein:
the shaft is cylindrical;
the head is circular and concentric with the shaft; and
the barrel is concentric with and has a diameter greater than the shaft.
5 . The information handling system of claim 4 , wherein an axis of the shaft is substantially perpendicular with the surface of the circuit board.
6 . An information handling resource comprising:
a circuit board;
a connector mounted to a surface of the circuit board and configured to electrically couple to a corresponding connector mounted to a surface of a second circuit board of a second information handling resource;
a first standoff extending from a surface of the circuit board; and
a second standoff extending from the surface and arranged relative to the first standoff such that the first standoff and the second standoff are configured to mechanically engage with engagement features of the second information handling resource to define an axis of pivot between the circuit board and the second circuit board to align the connector to the corresponding connector.
7 . The information handling system of claim 6 , the information handling resource further comprising a threaded insert configured to mechanically couple to a captive screw maintained within the second circuit board.
8 . The information handling system of claim 6 , wherein at least one of the first standoff and the second standoff comprises:
a shaft extending from the surface of the circuit board;
a head coupled to the end of the shaft; and
a barrel formed around a portion of the shaft, such that the shaft includes an engagement region on a surface of the shaft located between the head and the barrel and configured to mechanically engage with an engagement feature of the second information handling resource to define the axis of pivot.
9 . The information handling system of claim 8 , wherein:
the shaft is cylindrical;
the head is circular and concentric with the shaft; and
the barrel is concentric with and has a diameter greater than the shaft.
10 . The information handling system of claim 9 , wherein an axis of the shaft is substantially perpendicular with the surface of the circuit board.
11 . An information handling resource comprising:
a circuit board;
a connector mounted to a surface of the circuit board and configured to electrically couple to a corresponding connector mounted to a surface of a second circuit board of a second information handling resource;
a first standoff engagement feature formed in an edge of the circuit board; and
a second standoff engagement feature formed in the edge of the circuit board such that the first standoff engagement feature and the second standoff engagement feature are configured to mechanically engage respectively to a first standoff and a second standoff extending from a surface of the second circuit board to define an axis of pivot between the circuit board and the second circuit board to align the connector to the corresponding connector.
12 . The information handling resource of claim 11 , the information handling resource further comprising a captive screw maintained within the circuit board configured to mechanically couple to a threaded insert of the second information handling resource.
13 . The information handling resource of claim 12 , the captive screw located proximate to a second edge of the circuit board opposite from the edge.
