Abstract
A hermetically-sealed hard disk drive (HDD) utilizes a laminated film seal to seal an interface of an electrical flexible cable assembly and an HDD enclosure base. The laminated film seal may be constructed of a heat sealant layer that bonds with a surface of the base and a surface of the flex cable, a barrier layer which inhibits gas from escaping from inside the HDD, and a film surface protective layer which protects the heat sealant and barrier layers. Embodiments may include a heat sealant layer comprising a thermoplastic polymer such as polypropylene, a barrier layer comprising a metal such as aluminum, and a film surface protective layer comprising a thermoplastic polymer such as polyethylene terephthalate.
