  • Method and apparatus for a probe card
    Patent number: 9921262
    Abstract: An integrated apparatus and method to provide test, diagnostics and characterization access to backplane electrical signals during electronic product development is presented. The apparatus removes need for manual and ad hoc connections made in an engineering laboratory or assembly line which make the process prone to damage of the components, inaccurate measurements and arbitrary fluctuations in function. The method and apparatus is a mechanized way to connect backplane signals to corresponding drivers, receivers and test equipment through probes placed on equidistant electrical traces, reducing inter signal variations.
    Type: Grant
