Abstract

Approaches herein provided surface mounted devices each configured as a stand-alone component suitable for attachment to a substrate such as a printed circuit board (PCB). In some embodiments, a method includes forming a base housing, coupling an electronic component to the base housing, and forming a cover over the electronic component, wherein the cover is coupled to the base housing. The electronic component may include a fusible link/element extending between terminals, the terminals wrapped around an exterior of base housing. The device may then be coupled to the PCB, for example, by attaching the terminals to an upper surface of the PCB.

First claim

The invention claimed is:

1. A method of forming devices, the method comprising:
providing a plurality of base housings;
coupling an electronic component to each of the base housings, the electronic component including a set of terminals extending along an outer surface of each of the base housings;
providing a carrier tape including a plurality of covers coupled to first and second edges by a set of connectors;
forming a plurality of devices by coupling the carrier tape to the plurality of base housings, wherein the plurality of covers is directly secured to the plurality of base housings;
decoupling the set of connectors of the carrier tape from the first and second edges to extract each of the plurality of devices from the carrier tape.

2. The method according to claim 1 , further comprising coupling the device to a substrate.

3. The method according to claim 1 , further comprising coupling the set of terminals of the electronic component to a printed circuit board.

4. The method according to claim 1 , further comprising inserting the electronic component within a recess formed in the base housing.

5. The method according to claim 1 , further comprising forming the set of terminals along a bottom surface of the base housing.

6. The method according to claim 5 , further comprising extending the set of terminals through corresponding terminal channels formed in a pair of opposing end walls of the base housing.

7. A method of forming surface mounted devices, the method comprising:
providing a plurality of base housings;
coupling an electronic component to each of the plurality of base housings, the electronic component including a fusible element extending between a set of terminals;
providing a carrier tape including a plurality of covers coupled to first and second edges by a set of connectors;
forming a plurality of surface mounted devices by coupling the carrier tape to the plurality of base housings, wherein the plurality of covers is directly secured to the plurality of base housings;
decoupling the set of connectors of the carrier tape from the first and second edges to extract each of the plurality of surface mounted devices from the carrier tape;
coupling the electronic component to a printed circuit board.

8. The method according to claim 7 , further comprising inserting the electronic component within a recess formed in the base housing.

9. The method according to claim 7 , further comprising forming the set of terminals along a bottom surface of the base housing.

10. The method according to claim 9 , further comprising extending the set of terminals through corresponding terminal channels formed in a pair of opposing end walls of the base housing.

11. The method according to claim 10 , further comprising wrapping the set of terminals around an exterior surface of the pair of opposing end walls of the base housing.
