Abstract
A test socket comprising a guide plate with a lower surface engaged with an upper surface of a main test structure, the guide plate further including an upper surface which is parallel to the lower surface and an opening extending through the guide plate, the main test structure includes a body with one or more apertures through the upper surface and one or more probes mounted within the main test structure, the probes including a front end which extends through the apertures for engagement by a lead or terminal pad of a device to be tested, and a tail end which is secured within the main test structure by an elastomeric material.
Claims19
A test socket comprising:
- a guide plate with a lower surface engaged with an upper surface of a main test structure, said guide plate further including an upper surface, which is parallel to the lower surface, and an opening extending through the guide plate;
- the main test structure includes a body with one or more apertures through the upper surface;
- one or more probes mounted within the main test structure, said probes including a front end which extends through said apertures for engagement by a lead or terminal pad of a device to be tested, and a tail end which is secured within the main test structure by an elastomeric material;
- wherein the one or more probes further include a body with the front end emanating from a front extension and the tail end emanating from a tail extension, and the body includes an arcuate surface which engages a trace within the main test structure;
- wherein the front extension further includes a linear portion which engages a first seat within the main test structure when engaged by the device to be tested;
- and
- wherein the tail end engages a second seat located proximally to the elastomeric material.
A test socket comprising:
- a guide plate with a lower surface engaged with an upper surface of a main test structure, said guide plate further including an upper surface, which is parallel to the lower surface, and an opening extending through the guide plate;
- the main test structure includes a body with one or more apertures through the upper surface;
- and
- one or more probes mounted within the main test structure, said probes including a front end emanating from a front extension which extends through said apertures for engagement by a lead or terminal pad of a device to be tested, and a tail end emanating from a tail extension which is secured within the main test structure by an elastomeric material, and the body includes an arcuate surface which engages a trace within the main test structure;
- wherein the front extension further includes a linear portion which engages a first seat within the main test structure when engaged by the device to be tested;
- and
- wherein the tail end includes a narrowed section and an expanded end which engages a second seat located proximally to the elastomeric material to maintain the probe in a desired position/orientation.
A test set mounted to a load board or a tester apparatus to electrically connect one or more leads or terminal pads of a device to be tested with a corresponding metallic trace on the load board comprising:
- a test socket including:
- a guide plate with a lower surface engaged with an upper surface of a main test structure, said guide plate further including an upper surface, which is parallel to the lower surface, and an opening extending through the guide plate;
- the main test structure includes a body with one or more apertures through the upper surface;
- and
- a plurality of probes mounted within the main test structure, said probes including a front end emanating from a front extension which extends through said apertures for engagement by a lead or terminal pad of a device to be tested, and a tail end emanating from a tail extension which is secured within the main test structure by an elastomeric material, and the body includes an arcuate surface which engages a trace on the load board or tester apparatus;
- wherein the front extension further includes a linear portion which engages a first seat within the main test structure when engaged by the device to be tested;
- and
- wherein the tail end includes a narrowed section and an expanded end which engages a second seat located proximally to the elastomeric material to maintain the probe in a desired position/orientation.
