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.

Disc Pin Joining
This proposal suggests an alternate configuration for pin joining to
In the proposed approach, the iron-nickel disc 1, in Fig. 1, would be first
attached to the pin 2 using a high melting point alloy 3. The iron-nickel disc is
selected to provide an interface with a coefficient of thermal expansion matched
to the substrate. In the assembly, as shown, a top plate 4 would be used to hold
the disc in the disc nest 5. The plate would be secured to the pin nest 6 by
screws 7. A pin weight 8 would complete the assembly. During reflow or pin
joining, the assembly would be turned upside down.
Once the pin joining has been completed, the top plate may be removed and
replaced with the substrate and the pin disc assembly joined to the substrate
using a tin-lead alloy. The schematic, as depicted, is for a single pin; however, in
practice, it would be used for a multitude of pins.
