Test socket and method for fabricating the same

A method of fabricating a test socket that supports a probe stretchable in a longitudinal direction, the method comprising:

• forming, by a drill, a first recessed part with a predetermined depth on one surface of a first base member made of a conductive material at a position where the probe is disposed;
• forming, by the drill, a first probe support part by filling the first recessed part with an insulating material;
• forming, in a single process and by the drill, a first probe accommodating hole for accommodating the probe in the first base member at a position corresponding to the first recessed part and a first support hole, through the probe hole, for supporting one end portion of the probe in the first probe support part;
• forming a second support hole for supporting the other end portion of the probe in a cover member made of an insulating material;
• inserting the probe into the first probe accommodating hole and supporting one end portion and the other end portion of the probe in the first support hole and the second support hole, respectively;
• and
• joining the cover member to another surface of the first base member.

A method of fabricating a test socket that supports a probe stretchable in a longitudinal direction, the method comprising:

• forming a probe accommodating hole for accommodating the probe in a base block made of a conductive material;
• forming first and second through holes in positions corresponding the probe accommodating hole in a first base member and a second base member of a conductive material, respectively;
• forming first and second probe support portions by filling an insulating material in the first and second through holes;
• forming first and second support holes for supporting both ends of the probe in the first and second probe support portions;
• inserting the probe into the probe accommodating hole, supporting both ends of the probe in the first and second support holes;
• and
• joining the first and second base members to upper and lower surfaces of the base block, respectively.

A method of fabricating a test socket that supports a plurality of probes stretchable in a longitudinal direction, the method comprising:

• forming a plurality of through holes penetrating in a thickness direction in a first base block made of a conductive material;
• filling an insulating material into the plurality of through holes;
• forming a first probe accommodating hole for accommodating the plurality of probes in an insulating material in the plurality of through holes;
• and
• inserting the plurality of probes into the first probe accommodating hole,
• wherein the insulating material is removed so that an air layer is provided between an outer surface of some of the plurality of probes and an inner wall of a through hole of the plurality of through holes, and
• the insulating material is interposed between an outer surface of a rest of the plurality of probes and the inner wall of the through hole of the plurality of through holes.
