Abstract

Various embodiments of the invention relate to enclosure assemblies housing at least one electronic board assembly and systems (e.g., missiles or unmanned vehicles) that may employ such enclosure assemblies. In an embodiment, an enclosure assembly includes an enclosure having an interior surface defining an interior space and an inner diameter. At least one electronic board assembly is positioned within the interior space and includes a first peripheral edge region and an opposing second peripheral edge region. The electronic board assembly extends diametrically so that the first and second peripheral edge regions are at least proximate to the interior surface. In another embodiment, a plurality of electronic board assemblies are positioned within the interior space and each extends generally along a respective non-diametric chord defined by the interior surface.

an enclosure including an interior surface defining an interior space and an inner diameter; and

at least one electronic board assembly positioned within the interior space and including a first peripheral edge region and an opposing second peripheral edge region, the at least one electronic board assembly extending diametrically so that the first and second peripheral edge regions are at least proximate to the interior surface, the electronic board assembly comprising a PCI mezzanine board having a PCI bus interface wherein the first and second peripheral edge regions comprise edges other than the PCI bus interface.

2. The enclosure assembly of claim 1 wherein at least one electronic board assembly comprises a plurality of electronic board assemblies longitudinally spaced and each including a corresponding first peripheral edge region and a corresponding opposing second peripheral edge region, each electronic board assembly generally lying in a different plane and extending diametrically so that each corresponding first peripheral edge region and each corresponding opposing second peripheral edge region is at least proximate to the interior surface.

3. The enclosure assembly of claim 1 wherein the interior surface comprises first and second longitudinally extending slots formed therethrough, the first peripheral edge region of the at least one electronic board assembly inserted into the corresponding first longitudinally extending slot and the second peripheral edge region of the at least one electronic board assembly inserted into the corresponding second longitudinally extending slot.

4. The enclosure assembly of claim 3 wherein the at least one electronic board assembly comprises:

a first locking device attached to the first peripheral edge region, and received by and locked within the first longitudinally extending slot; and

a second locking device attached to the second peripheral edge region, and received by and locked within the second longitudinally extending slot.

5. The enclosure assembly of claim 1 wherein the at least one electronic board assembly comprises:

a first mounting device attached to the first peripheral edge region that engages a first mount associated with the enclosure; and

a second mounting device attached to the second peripheral edge region that engages a second mount associated with the enclosure.

6. The enclosure assembly of claim 1 wherein the inner diameter of the enclosure is about 4 inch.

7. The enclosure assembly of claim 1 wherein the at least electronic board assembly comprises external electrical connectors that are not located within a peripheral edge region thereof.

8. The enclosure assembly of claim 1 wherein the at least one electronic board assembly comprises:

a carrier substrate including a first side and an opposing second side;

a first electronic circuit board mounted to the first side and operatively coupled to the carrier substrate; and

a second electronic circuit board mounted to the second side and operatively coupled to the carrier substrate.

9. The enclosure assembly of claim 8 wherein:

the first electronic circuit board comprises the PCU mezzanine board as a first PCI mezzanine board; and

the second electronic circuit board comprises a second PCI mezzanine board.

10. The enclosure assembly of claim 1 wherein the at least one electronic board assembly comprises:

a carrier board including a first side and an opposing second side;
