What is claimed is:

1. A surface mountable electronic device, comprising:

a packaged body having a mounting surface, the mounting surface having a plurality of recesses at side edges of the body and

a plurality of electrical contacts, each of which extends from an interior portion of the mounting surface and terminates in one of said recesses, and each of which conforms to one of said recesses, wherein said recesses and electrical contacts are sized to provide offsets between said mounting surface and said electrical contacts.

2. The device of claim 1, wherein at least a portion of each electrical contact conforms to at least a portion of a recess that is substantially parallel to said mounting surface.

3. The device of claim 1, wherein at least a portion of each electrical contact conforms to at least a portion of a recess that is not parallel to said mounting surface.

4. The device of claim 3, wherein said portions of the recesses that are not parallel to said mounting surface are orthogonal to said mounting surface.

5. The device of claim 3, wherein said portions of the recesses that are not parallel to said mounting surface extend diagonally from said mounting surface.

6. The device of claim 1, wherein each recess comprises:

a diagonal portion extending diagonally from said mounting surface; and

a parallel portion extending substantially parallel to said mounting surface, between the diagonal portion and an edge of the device.

7. The device of claim 1, wherein said electrical contacts are heat sinks.

8. The device of claim 1, wherein the device is selected from a group comprising an opto-electric device and a light-emitting device.

9. The device of claim 1, wherein each recess comprises:

an orthogonal portion extending orthogonally from said mounting surface; and

a parallel portion extending substantially parallel to said mounting surface, between the orthogonal portion end an edge of the body.

10. The device of claim 1, wherein each recess extends diagonally from said mounting surface to an edge of said body.

11. The device of claim 1, wherein one or more of the recesses is bounded on three sides.

12. The device of claim 1, wherein one or more of the recesses extends the entire length of the side edge at which it is formed.

13. Apparatus, comprising:

a printed circuit board having a plurality of pads thereon;

a surface mountable electronic device, comprising:

a packaged body having a mounting surface, the mounting surface having a plurality of recesses at side edges of the body; and

a plurality of electrical contacts, each of which extends from an interior portion of the mounting surface and terminates in one of said recesses, and each of which conforms to one of said recesses, wherein said recesses and electrical contacts are sized to provide offsets between said mounting surface and said electrical contacts; and

conductive adhesive, electrically and mechanically coupling each electrical contact of the surface mountable electronic device to a corresponding pod on the printed circuit board, the conductive adhesive being substantially confined to said recesses.

14. The apparatus of claim 13, wherein a plurality of said surface mountable electronic devices are mounted in an array on the printed circuit board.
