Abstract
In the context of a hard disk drive (HDD), an adhesive leak channel structural feature is positioned in an area at which an electrical feed-through is adhered with an adhesive to an enclosure base, where the leak channel feature inhibits the leakage of gas through the adhesive. Embodiments include providing the leak channel feature on the base and/or on the feed-through. Embodiments may further include application of an electrodeposition coating to the base in an area at which the adhesive is in contact.
