PPI WebSep 1, 2009 · One method also described in the AEC Q-100 is the so-called dynamic part average testing (DPAT). The basic idea is that electrical parameters that do not fall into a normal distribution are suspicious and are considered to be more likely to cause critical field rejects contradicting the zero ppm target in automotive applications. The process of ...
Weboutlier detection methods such as static/dynamic part average test (S/DPAT) [5]–[8], and nearest neighbor residual (NNR) [9]–[11], and location average [9], [12] were proposed and are commonly employed in the industry. Multivariate outlier detection methods were also proposed for screening rare defects and customer returns [13], [14].
