Abstract

Claims (27)

1 . A test fixture comprising:

a testing board configured to receive a surface mount device; and

at least one testing interface configured to connect the testing board with the surface mount device and configured to compensate for planar deviations of the connection between the surface mount device and the at least one testing interface.

2 . A test fixture in accordance with claim 1 further comprising a resilient grounding member, the at least one testing interface engaging a top of the resilient grounding member.

3 . A test fixture in accordance with claim 2 wherein the resilient grounding member is configured to allow vertical movement of the at least one testing interface relative to the testing board.

4 . A test fixture in accordance with claim 1 wherein the at least one testing interface comprises an interface portion and a based portion flexibly connected together.

5 . A test fixture in accordance with claim 4 further comprising a flexible extension extending from the interface portion and configured to connect to a connection strip of the base portion allowing upward and downward movement of the base portion relative to the interface portion.

6 . A test fixture in accordance with claim 4 further comprising a gap between the base portion and the interface portion.

7 . A test fixture in accordance with claim 1 wherein the at least one testing interface extends above a top surface the testing board.

8 . A test fixture in accordance with claim 1 further comprising a gap between the at least one testing interface and the testing board.

9 . A test fixture in accordance with claim 1 further comprising a mounting portion configured to receive therein at least a portion of the surface mount device.

10 . A test fixture in accordance with claim 9 further comprising a vacuum port in combination with the mounting portion.

11 . A test fixture in accordance with claim 1 further comprising mounting points configured to mount alignment members to the testing board.

12 . A test fixture in accordance with claim 1 wherein the surface mount device comprises at least one of a surface mount ferrite isolator and a surface mount ferrite circulator.

13 . A test fixture in accordance with claim 1 further comprising at least one recessed portion configured to receive therein a portion of the at least one testing interface.

14 . A test fixture in accordance with claim 13 further comprising at least another recessed portion below the at least one recessed portion and configured to receive therein a resilient grounding member.

15 . A test fixture in accordance with claim 1 wherein the at least one testing interface is configured to move in a z-direction and resist movement in both an x-direction and a y-direction.

16 . A surface mount device test fixture comprising:

a testing board configured to support a ferrite type surface mount device;

a plurality of testing interfaces configured to connect the ferrite type surface mount device to a ground plane of the testing board, the plurality of testing interfaces configured to move perpendicularly relative to the testing board; and

a resilient grounding member supporting each of the plurality of testing interfaces.

17 . A surface mount device test fixture in accordance with claim 16 wherein each of the plurality of testing interfaces comprises a base portion and an interface portion flexibly connected to the base portion to allow the perpendicular movement.

18 . A surface mount device test fixture in accordance with claim 16 wherein the resilient grounding member comprises a foam rubber material, at least a portion of the resilient grounding member surrounded by a conductive layer.

19 . A surface mount device test fixture in accordance with claim 16 wherein the plurality of testing interfaces extend above the ground plane of the testing board.

20 . A method for testing a surface mount device, the method comprising:

configuring a testing board to receive a surface mount device; and

movingly engaging at least one testing interface with the testing board, the at least one testing interface configured to connect the surface mount device to the testing board.
