Abstract:
1. A method for determining the quality of an individual electronic product including the reliability of said individual electronic product using both its own local healthy baseline, and a global healthy baseline derived from multiple units of the same electronic product comprising: establishing during the manufacturing process said individual electronic product's own local healthy baseline using electronically recorded and stored performance values, signal values, or calculated parameters, along with electronically recorded environmental and operational loads, or their correlations measured during manufacturing; establishing a global healthy baseline built from multiple local healthy baselines derived during the manufacturing process from multiple units of said same electronic product; electronically storing the said local and global healthy baselines within said electronic product or within an external database; and, with the aid of a computer, comparing performance, signal values and parameters, environmental and operational load, or their correlations of the said individual electronic product against said global healthy baseline for said same electronic product in a product screening or diagnostics step which is performed during the manufacturing process for anomaly detection, to confirm that said individual electronic product meets performance specifications.
