Abstract

A holder for a compression attached memory module (CAMM) includes a spine and first and second beam protrusions. The spine encloses an end of the CAMM adjacent to a contact pad array of a CAMM printed circuit board (PCB) of the CAMM. The first beam protrusion extends from the spine away from the end of the CAMM. The second beam protrusion extends from the spine away from the end of the CAMM. When the CAMM is installed into the holder and installed into an information handling system, the first and second beam protrusions transfer a compression applied at the first and a compression applied at the second beam protrusions to a portion of the spine between the first beam protrusion and the second beam protrusion to limit a deformation of the CAMM PCB.

First claim

What is claimed is:

1 . A holder for a compression attached memory module (CAMM), the holder comprising:
a spine to enclose an end of the CAMM adjacent to a contact pad array of a CAMM printed circuit board (PCB) of the CAMM; a first beam protrusion extending from the spine away from the end of the CAMM; and a second beam protrusion extending from the spine away from the end of the CAMM, wherein when the CAMM is installed into the holder and installed into an information handling system, the first and second beam protrusions transfer a compression applied at the first and a compression applied at the second beam protrusions to a portion of the spine between the first beam protrusion and the second beam protrusion to limit a deformation of the CAMM PCB.

2 . The holder of claim 1 , wherein the first beam protrusion includes a first screw hole associated with a first screw hole of the CAMM, and the second beam protrusion includes a second screw hole associated with a second screw hole of the CAMM.

3 . The holder of claim 2 , wherein, when the CAMM is installed into the holder and installed into an information handling system, the compression applied at the first beam protrusion and the compression applied at the second beam protrusion are applied via respective first and second screw holes.

4 . The holder of claim 1 , further comprising:
a third beam protrusion extending from the spine away from the end of the CAMM, wherein, when the CAMM is installed into the holder and installed into an information handling system, the second and third beam protrusions transfer the compression applied at the second beam protrusion and a compression applied at the third beam protrusions to a portion of the spine between the second beam protrusion and the third beam protrusion to limit the deformation of the CAMM PCB.

5 . The holder of claim 4 , wherein the third beam protrusion includes a third screw hole associated with a third screw hole of the CAMM.

6 . The holder of claim 5 , wherein, when the CAMM is installed into the holder and installed into an information handling system, the compression applied at the third beam protrusion is applied via the third screw hole.

7 . The holder of claim 1 , wherein the spine includes a detent structure to provide a prestress to the CAMM PCB.

8 . The holder of claim 7 , wherein the prestress further limits the deformation of the CAMM PCB.

9 . The holder of claim 1 , wherein the spine has an arch shape to provide a prestress to the CAMM PCB.

10 . The holder of claim 9 , wherein the prestress further limits the deformation of the CAMM PCB.

11 . A method for providing a holder for a compression attached memory module (CAMM), the method comprising:
providing, on the holder, a spine to enclose an end of the CAMM adjacent to a contact pad array of a printed circuit board (PCB) of the CAMM; providing, on the holder, a first beam protrusion extending from the spine away from the end of the CAMM; and providing, on the holder, a second beam protrusion extending from the spine away from the end of the CAMM wherein, when the CAMM is installed into the holder and installed into an information handling system, the first and second beam protrusions transfer a compression applied at the first and a compression applied at the second beam protrusions to a portion of the spine between the first beam protrusion and the second beam protrusion to limit a deformation of the CAMM PCB.

12 . The method of claim 11 , further comprising:
providing, on the first beam protrusion, a first screw hole associated with a first screw hole of the CAMM; and providing, on the second beam protrusion, a second screw hole associated with a second screw hole of the CAMM.

13 . The method of claim 12 wherein, when the CAMM is installed into the holder and installed into an information handling system, the compression applied at the first beam protrusion and the compression applied at the second beam protrusion are applied via respective first and second screw holes.

14 . The method of claim 11 , further comprising providing a third beam protrusion extending from the spine away from the end of the CAMM, wherein when the CAMM is installed into the holder and installed into an information handling system, the second and third beam protrusions transfer the compression applied at the second beam protrusion and a compression applied at the third beam protrusions to a portion of the spine between the second beam protrusion and the third beam protrusion to limit the deformation of the CAMM PCB.

15 . The method of claim 14 , further comprising providing, on the third beam protrusion, a third screw hole associated with a third screw hole of the CAMM.

16 . The method of claim 15 , wherein, when the CAMM is installed into the holder and installed into an information handling system, the compression applied at the third beam protrusion is applied via the third screw hole.

17 . The method of claim 1 , further comprising providing, on the spine, a detent structure to provide a prestress to the CAMM PCB.

18 . The method of claim 17 , wherein the prestress further limits the deformation of the CAMM PCB.

19 . The holder of claim 11 , further comprising providing, on the spine, an arch shape to provide a prestress to further limit the deformation of the CAMM PCB.

20 . An information handling system, comprising:
a main printed circuit board (PCB); a compression connector; a compression attached memory module (CAMM); and a CAMM holder including:
a spine to enclose an end of the CAMM adjacent to a contact pad array of a CAMM printed circuit board (PCB) of the CAMM;
a first beam protrusion extending from the spine away from the end of the CAMM; and
a second beam protrusion extending from the spine away from the end of the CAMM wherein, when the CAMM is installed into the holder and installed into an information handling system, the first and second beam protrusions transfer a compression applied at the first beam protrusion and a compression applied at the second beam protrusion to a portion of the spine between the first beam protrusion and the second beam protrusion to limit a deformation of the CAMM PCB.
