A hermetic sealing approach involves welding an Aluminum cover onto a
low-cost Aluminum housing. According to an example embodiment of the
present invention, a metal housing having a base and sidewalls extending
upward therefrom is adapted to receive and couple to an HDD arrangement.
The metal housing is formed using material and processing (e.g., cold
formed or die cast Aluminum) that are relatively inexpensive. A
feedthrough arrangement including a plurality of communication pins
extends through an opening in the base and is coupled thereto, with the
communication pins adapted to pass signals between the inside and the
outside of the metal housing. A metal cover is welded to an upper portion
of the sidewalls and, with the feedthrough arrangement, hermetically
seals the metal housing.
