Abstract

The present embodiments provide apparatuses, systems and methods of manufacturing surface mountable devices. Some embodiments provide surface mount devices that comprise a casing comprising a recess formed in the casing and extending into the casing, an insert secured with the casing and extending about the recess defining a portion of a surface of the recess with the insert comprising a reflective surface exposed along the recess, and a plurality of leads partially exposed through the recess.

Claims

1. A surface mount device comprising:

a casing comprising a recess formed in the casing and extending into the casing;

an insert secured with the casing and extending about the recess defining a portion of a surface of the recess, wherein the insert comprises a ring circumferentially extending about and defining the portion of the surface of the recess, wherein the insert further has a first edge positioned proximate a surface of the casing, and a second edge distal from the surface of the casing, where the insert comprises four adjacent sections and tapers from the first edge to the second edge, the insert further comprising a reflective surface exposed along the recess; and

a plurality of leads partially exposed through the recess, at least one of said plurality of leads partially encased by and extending exterior to said casing.

2. The surface mount device of claim 1, wherein the ring has a height that is less than the height of the recess.

3. The surface mount device of claim 1, wherein the casing is at least partially constructed of black polyphthalamide material.

4. The surface mount device of claim 1, wherein each of the four sections are generally portions of circles each having a first radius proximate the second edge that is greater than a second radius proximate the first edge such that each section intersects two neighboring sections.

5. The surface mount device of claim 1, further comprising an electronic device coupled with a first lead of the first plurality of leads, wherein the recess exposes at least a portion of the electronic device.

6. A surface mount device comprising:

a casing comprising a tapered recess formed in the casing and extending into the casing;

an insert secured with the casing and extending about the recess defining a portion of a surface of the recess, wherein the insert comprises a ring circumferentially extending about and defining the portion of the surface of the recess, wherein the insert further comprises tabs that generally extend away from the reflective surface and into the casing, said tabs completely encased by said casing, the insert further comprising a reflective surface exposed along the recess; and

a plurality of leads partially exposed through the recess, at least one of said plurality of leads partially encased by and extending exterior to said casing.

7. A surface mount device comprising:

a casing comprising a tapered recess formed in the casing and extending into the casing;

an insert secured with the casing and extending about the recess defining a portion of a surface of the recess, wherein the insert comprises a reflective surface exposed along the recess, the insert further comprising a first edge positioned proximate an exterior surface of the casing, a second edge distal from the exterior surface of the casing, and a ledge proximate the first edge that extends away from the reflective surface and into the casing, said ledge further comprising tabs extending from the ledge into the casing, said tabs completely encased by said casing; and

a plurality of leads partially exposed through the recess, at least one of said plurality of leads partially encased by and extending exterior to said casing.

8. A surface mount device comprising:

a casing comprising a first surface and a recess formed in the casing extending from the first surface and into the casing;

a first plurality of leads extending from the recess through the casing and exiting the casing;

an electronic device coupled with at least one of the plurality of leads and at least partially exposed through the recess; and

an insert comprising a reflective surface, the insert extending about at least a portion of a surface of the recess and secured with the casing with the reflective surface of the insert exposed through the recess, wherein the insert is a ring extending entirely around a perimeter of the recess, wherein the insert further comprises a first edge proximate the first surface of the casing and a second edge distal from the first surface of the casing wherein the second edge comprises a plurality of adjoining segments, wherein the plurality of segments comprise four curved segments with each of the four curved segments having a first radius proximate the second edge that is greater than a second radius proximate the first edge of the insert.

9. The surface mount device of claim 8, wherein the reflective surface of the insert is generally frustoconical shaped.

10. A surface mount device comprising:

a casing comprising a tapered recess formed in the casing and extending into the casing;

an inwardly tapering insert distinct from and secured to the casing, wherein the insert is generally ring-shaped and circumferentially extends about a portion of the surface of the recess such that the insert defines at least a portion of the surface of the recess, said insert further comprising tabs extending into said casing, said tabs completely encased by said casing.

11. The surface mount device of claim 10, wherein the insert has a height that is less than the height of the recess.

12. The surface mount device of claim 10, wherein the casing is at least partially constructed of a black material.

13. The surface mount device of claim 10, wherein the casing is at least partially constructed of black polyphthalamide material.

14. The surface mount device of claim 10, further comprising a plurality of leads partially exposed through the recess, at least one of said plurality of leads partially encased by and extending exterior to said casing.

15. The surface mount device of claim 14, further comprising an electronic device coupled with at least one of the plurality of leads and at least partially exposed through the recess.

16. The surface mount device of claim 10, wherein the insert is tapered such that an opening opposite the recess surface is larger than an opening adjacent to the recess surface.

17. A surface mount device comprising:

a casing comprising a recess formed in the casing and extending into the casing;

an inwardly tapering insert distinct from and secured to the casing, wherein the insert is generally ring-shaped and circumferentially extends about a portion of the surface of the recess such that the insert defines at least a portion of the surface of the recess, said insert further comprising tabs extending into said casing, wherein the insert comprises four adjoining segments, each of said segments having a curved shape.
