Test socket

1 . A test socket comprising:

a connection portion;

a frame supporting the connection portion; and

a heating wire disposed on the frame,

wherein the frame comprises:

a plate; and

a support film disposed on top of the plate;

wherein the heating wire is disposed on the support film;

the test socket further comprising a relay terminal disposed in a hole penetrating the plate,

wherein an upper portion of the relay terminal overlaps and contacts a terminal of the heating wire, and a lower portion of the relay terminal overlaps and contacts a power terminal of a test board; and

wherein the connection portion comprises an anisotropic conductive sheet, and the anisotropic conductive sheet includes an insulating portion of an elastic insulating material and a conductive portion including at least one conductive particle.

2 . The test socket according to claim 1 , wherein the heating wire is disposed on at least one surface of a first surface and a second surface of the frame.

3 . The test socket according to claim 2 , wherein the first surface of the frame is a surface facing a socket guide, and

the second surface of the frame is a surface opposite to the first surface.

4 . The test socket according to claim 3 , wherein at least a portion of the heating wire is disposed between the first surface of the frame and the socket guide.

5 . The test socket according to claim 3 , wherein at least a portion of the heating wire is disposed between the second surface of the frame and a test device.

6 . The test socket according to claim 1 , wherein the heating wire is printed or deposited onto the frame.

7 . The test socket according to claim 1 , wherein the frame includes:

a main body having a connection hole; and

an extension portion extending from the main body.

8 . The test socket according to claim 7 , wherein a terminal of the heating wire is disposed on the extension portion.

9 . The test socket according to claim 1 , wherein the heating wire surrounds a center of the frame and includes a plurality of heating wires respectively arranged at different distances from the center of the frame.

10 . The test socket according to claim 1 , wherein the heating wire includes a plurality of heating wires arranged along different sides of the frame, respectively.

11 . The test socket according to claim 1 , wherein the frame includes at least one coupling hole, and

at least a portion of the heating wire has a shape surrounding the coupling hole.

12 . The test socket according to claim 1 , wherein the connection portion further includes a support sheet on the anisotropic conductive sheet.

13 . A test socket comprising:

a connection portion;

a frame supporting the connection portion;

a heating wire disposed on the frame; and

a socket guide disposed on the frame,

wherein the frame comprises:

a plate; and

a support film disposed on top of the plate;

wherein the heating wire is disposed on the support film;

the test socket further comprising a relay terminal disposed in a hole penetrating the plate,

wherein an upper portion of the relay terminal overlaps and contacts a terminal of the heating wire, and a lower portion of the relay terminal overlaps and contacts a power terminal of a test board; and

wherein the connection portion comprises an anisotropic conductive sheet, and the anisotropic conductive sheet includes an insulating portion of an elastic insulating material and a conductive portion including at least one conductive particle.

14 . The test socket according to claim 13 , wherein at least a portion of the heating wire overlaps the socket guide.

15 . The test socket according to claim 13 , wherein at least a portion of the heating wire contacts the socket guide.
