Hermetic sealed electrical connector with high-speed transmission for hard disk drive

A barrier structure for hermetically sealing an electronic device, comprising:

• a dielectric material having a first surface and a second surface opposite the first surface;
• a first plurality of connecting pads disposed on the first surface;
• a second plurality of connecting pads disposed on the second surface;
• a plurality of conductors embedded in the dielectric material, wherein each conductor has a first end adjacent a corresponding connecting pad of the first plurality of connecting pads and a second end adjacent a corresponding connecting pad of the second plurality of connecting pads;
• a first ground layer embedded in the dielectric material, wherein the first ground layer is coplanar with the first end of each conductor;
• a second ground layer embedded in the dielectric material, wherein the second ground layer is coplanar with the second end of each conductor;
• and
• one or more layers embedded in the dielectric material, wherein the one or more layers are located between the first and second ground layers.

An electronic device, comprising:

• and
• a hermetic electrical connector, comprising:
• an external connector;
• an internal connector;
• and
• a barrier structure disposed between the external connector and the internal connector, wherein the barrier structure comprises:
• a dielectric material having a first surface and a second surface opposite the first surface;
• one or more layers embedded in the dielectric material, wherein the one or more layers each includes a plurality of openings;
• and
• a plurality of conductors embedded in the dielectric material, wherein each conductor extends through a corresponding opening of the plurality of openings of each layer.
