scope:

This standard was revised to clarify assumptions necessary to estimate AOQ, revise the minimum sample size algorithm, address small sample size concerns, and provide methods for combining groups for AOQ estimation. Derivation of any new methods for combing groups for AOQ estimation. Derivation of any new methods introduced into this document have been provided in annexes. A statistical method is based on confidence interval statistics. A procedure was established for reporting AOQ when the minimum sample size criterion is not met. Not all sections of EIA-554 are appropriate for use by device manufacturers therefore JEDEC wishes to continue using JESD16A. In December 2008 the formulating committee approved to remove EIA-554 (July 1996, Reaffirmed September 2002) from the JEDEC website.
