Abstract
Embodiments disclosed herein generally relate to hermetic electrical connectors used in hard disk drives. The hermetic electrical connector includes a barrier structure having a first plurality of connecting pads disposed on a first surface of the barrier structure and a second plurality of connecting pads disposed on a second surface of the barrier structure opposite the first surface. A plurality of conductors is disposed within the barrier structure, and each conductor is coupled to a connecting pad of the first plurality of connecting pads and a corresponding connecting pad of the second plurality of connecting pads. The barrier structure further includes a dielectric material between the first and second surfaces, and one or more layers embedded in the dielectric material. The addition of the layers helps choke the helium gas flow, thus improving sealing of the electrical connector while maintaining high-speed electrical transmission.
