scope:
This document defines standard methodologies for calculating defects per million opportunities (DPMO) metrics related to electronic printed board assembly processes. It is intended for use in measuring in-process assembly steps rather than end product determination. Calculation of completed item DPMO is addressed in IPC-7912.
Additionally, a guide to defect categorization is provided that when used with IPC/EIA J-STD-001 and IPC-A-610 can serve as a base for summarizing and reporting in-process defects.
Note: This document does not dictate the number of assemblies or data points needed to calculate DPMO metrics.
