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.

Ceramic Substrate With Recessed Pins
The number of process steps can be reduced and a larger circuitizing area
made available by recessing I/0 pins within a ceramic substrate prior to
metallization of the substrate.
In the figure, substrate 1 is formed with a recess 2 in which is inserted a pin 3
having head 4. The upper surface of the substrate is then metallized with
conventional techniques, and the pins are soldered on the lower side.
Thereafter, the metal coating is covered with resist, exposed, developed and
etched to form circuits 5, and the resist is stripped. The pins may be swaged,
and components, such as chips, can be added to the circuits.
