Claims
- 1. A portable peripheral card comprising:
- a printed circuit board (PC board) having an active region where one or more electrical components are mounted;
- an electrical connector attached to the PC board, whereby external devices electrically access said one or more electronic components via said electrical connector;
- a solid package encapsulating the PC board yet leaving a portion of said electrical connector exposed, said solid package being composed of a conductive segment and a non-conductive segment;
- a conductive layer overlying a portion of said package and including a plurality of extensions extending into said package and in contact with the conductive segment of the package.
- 2. A portable peripheral card as recited in claim 1 wherein said non-conductive segment encapsulates said active region of the PC board, and said conductive segment encapsulates a remaining outer perimeter of the PC board surrounding said active region.
- 3. A portable peripheral card as recited in claim 1 wherein said conductive segment is metal and said non-conductive segment is polymer.
- 4. A portable peripheral card as recited in claim 3 wherein said polymer is thermoset plastic material.
- 5. A portable peripheral card as recited in claim 3 wherein said metal is pre-fabricated and is clamped to the PC board.
- 6. A portable peripheral card as recited in claim 1 wherein said conductive segment is filled polymer and said non-conductive segment is polymer.
- 7. A portable peripheral card as recited in claim 1 wherein said conductive segment is thermoplastic material and said non-conductive segment is thermoset plastic material.
- 8. A portable peripheral card as recited in claim 6 wherein a conductive trace travels around said outer perimeter of the PC board and electrically contacts said electrical connector.
- 9. A portable peripheral card as recited in claim 8 wherein said conductive trace is a ground trace.
- 10. A portable peripheral card as recited in claim 1 wherein said conductive layer is secured to said solid package via a conductive adhesive.
- 11. A portable peripheral card as recited in claim 10 wherein said conductive adhesive is z-axis adhesive.
- 12. A portable peripheral card as recited in claim 1 wherein said peripheral card is a PCMCIA card.
- 13. The portable peripheral card of claim 1 wherein the conductive layer is metal.
- 14. The portable peripheral card of claim 1 wherein the non-conductive segment of the package defines at least one cavity therein.
