Abstract
A ducted test socket for thermally testing a device under test (DUT) is provided that can accommodate a large DUT and will improve the thermal transfer efficiency between a precision temperature forcing system (PTFS) and the DUT. The ducted test socket comprises a carrier and a base with opposing, mated cavities and holes. These cavities and holes channel airflow around the entire DUT body and out outlet ports.
Claims20
A test socket for a device, the test socket comprising:
- a carrier having a generally flat top surface, a first plurality of upstanding walls extending from the top surface to a carrier bottom edge to define a first interior cavity below the top surface;
- and
- a base, wherein the base comprises a generally flat middle surface, a second plurality of upstanding walls extending from the middle surface to a base top edge of the base to define a second interior cavity, a first hole extending both above and below the middle surface, a plurality of channels that lie below the middle surface, and a first plurality of outlet ports,
- wherein each of the plurality of channels extends from the first hole to one of the first plurality of outlet ports.
1 more element
A method of testing a device, the method comprising:
- implanting the device within a first interior cavity of a carrier;
- mating the carrier to a base, wherein the device rests within the first interior cavity and a second interior cavity, wherein the second interior cavity is located within the base;
- forcing air through a thermal head into a first hole extending through the carrier and a second hole extending through the base;
- channeling the air from the second hole through a plurality of channels;
- and
- forcing the air to exit the plurality of channels via a plurality of outlet ports.
3 more elements
A test socket for a device, the test socket comprising:
- a carrier having a first cavity formed by a generally flat first surface and a first plurality of upstanding walls extending from the first surface to a first edge;
- and
- a base, wherein the base comprises a second plurality of upstanding walls extending from a second edge to a third edge, a generally flat second surface that lies between the second edge and the third edge, a first hole extending from the second surface to the third edge, and a plurality of channels that lie between the second surface and the third edge and that extend from the first hole to a first plurality of outlet ports.
