Abstract
A technique that uses component data, such as servo encoder feedback data, and calculates real time histograms on a production printed wire board assembly (PWBA). If the histograms are uploaded to a main controller at specific intervals during run, aberrant servo activity can be tracked over a period of time. This could lead to finding machine problems before they become serious enough to cause shutdowns.
