Abstract: Systems and methods are provided for identifying pages that can be authoritatively, to some confidence level or another, associated with a geographic location, and systems and methods for grouping documents such that authoritative location associations can be propagated from pages with higher location confidence to pages with lower location confidence. Pages might be identified with authoritative indicators, groups of pages identified including at least one addressed page and at least one unaddressed page, wherein an addressed page is a page having a higher confidence level than an unaddressed page, and at least one processing step performed that is location specific.

Abstract: The present invention is directed to techniques for obtaining an electrical characteristic of a circuit board assembly process which involves mounting a module to an installation location of a circuit board using the circuit board assembly process, and measuring leakage current of the test structure in response to an electrical signal (e.g., a voltage) applied to the installation location. One can then determine the surface insulation resistance (SIR) of the test structure based on the electrical signal and the leakage current in order to assess the suitability of the circuit board assembly process. One arrangement of the invention is directed to a system for obtaining an electrical characteristic of a circuit board assembly process.
