Dynamic part average testing dpat
WebJun 28, 2024 · In dynamic part average testing (DPAT), some parameters don’t have appropriate limits, while others have no limits at all, allowing “all” parts to pass and … Webproactive screening is justified. Techniques such as Dynamic Part Average Testing (DPAT) [1] aim to identify the passing die that exhibit marginal test measurements relative to the main distribution of each wafer. Once a wafer has completed wafer sort, the wafer-level distribution of all test measurements is known and robust statistics can be ...

On the … WebTest and data analytics vendors have developed a variety of different approaches to ensuring quality, ranging from outlier detection techniques involving dynamic part average testing (DPAT) to on-chip monitoring throughout a chip’s lifetime. The big problem today is in the data itself.
http://www.aecouncil.com/Documents/AEC_Q002_Rev_B1.pdf 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 ...
