Concept Search - What can I type?
For a concept search, you can enter phrases, sentences, or full paragraphs in English. For example, copy and paste the abstract of a patent application or paragraphs from an article.
Concept search eliminates the need for complex Boolean syntax to inform retrieval. Our Semantic Gist engine uses advanced cognitive semantic analysis to extract the meaning of data. This reduces the chances of missing valuable information, that may result from traditional keyword searching.

Disclosed is a method for a continuous wetting heatsink for test
and burn-in. Benefits include improved thermal performance, an improved test
environment, and improved ease of implementation.
� � � � � Conventional test handlers utilize liquid thermal interface
materials (TIMs). The liquid is applied only prior to the temporary attachment
of the device under test (DUT) to the heatsink. Test times are sometime long
and test temperatures are high enough to cause liquid loss via evaporation.
Performance degradation is often observed, impacting product yield and making
liquid interfaces impractical. No conventional solution exists for this
� � � � � Data exists which clearly demonstrates that the evaporation of
the liquid interface results in an increase in device junction temperature.
� � � � � The disclosed method
is a heatsink with microchannels or
based on a porous metal that enables the continuous wetting of the thermal
interface between the heatsink and the DUT for use in device testing and other
possible applications requiring a high performance temporary thermal interface.
� � � � � The disclosed method works on the principles of gravity and
capillary action, which under the correct design conditions draw liquid into
the interface between the heatsink and device under test.
