Abstract
A hermetic seal is provided for sealing a discrete opening in a disk drive base plate. The hermetic seal comprises a sealing gasket that is disposed between planar facing surfaces of a component inserted through the opening and a recess formed on the interior of the base plate. As the gasket is compressed, a deformable plating applied to the gasket deforms and flows to fill microscopic voids that may be found in the abutting planar surfaces. Required access to the disk drive through the opening may be made in a rework process without destroying the seal. To seal the opening of the drive again, the sealing gasket is simply recompressed between the planar abutting surfaces. The invention also comprises a method by which to seal the castings of the disk drive housing, to include the base plate and top cover the disk drive. The method generally includes a two-time resin impregnation process to fill exposed pores on the surface of the castings.
