Abstract
A method and apparatus for electrically interfacing between two or more distinct environments. The method and apparatus are directed to an electrical feedthru with exterior traces traversing a core. The electrical feedthru may be very small, facilitating its use in MEMS devices. The electrical feedthru may also include an over-mold shaped to create a mechanical seal between the two or more distinct environments without the use of an O-ring. The electrical feedthru is not limited to any particular geometry, it may be adapted to fit between any two environments, and thus the traces are not necessarily parallel to a central axis of the core.
Claims19
A method of fabricating an electrical feedthru comprising:
- providing an electrically insulating core having an external surface and a channel formed therein;
- adding a conductive material to the channel to create an electrical transmission line;
- and
- machining one of the external surface of the core, the electrical transmission line, or both, such that the electrical transmission line is flush with the external surface of the core.
