Brian Lee Chandler has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Method of analyzing electrical connection and test system
    Patent number: 7607824
    Abstract: A test system and method of analyzing a pin to circuit connection on a substrate is provided. The method includes applying thermal energy to the pin or the substrate at a location outside of the pin to circuit interface, and measuring infrared radiation near the pin to circuit interface. The method also includes the step of analyzing the measured infrared radiation to determine thermal energy distribution near the pin to circuit interface resulting from thermal conductivity at the interface. The method further includes the step of determining sufficiency of the pin to circuit electrical and mechanical connection based on the determined thermal energy distribution.
