IEC 60191-6-21:2010 provides a focused technical reference for the mechanical standardization of semiconductor device packages, specifically addressing measuring methods for package dimensions of small outline packages (SOP). For engineering teams, test laboratories, and procurement specialists, it supports consistent dimensional interpretation when reviewing package drawings, evaluating component fit, and preparing technical documentation. IEC 60191-6-21:2010 is most relevant where accurate outline definition and repeatable measurement practices are needed to support product evaluation and compliance workflows.

IEC 60191-6-21:2010 standard overview

This document forms part of the IEC 60191 series on mechanical standardization of semiconductor devices and is centered on the preparation of outline drawings for surface mounted packages. Its scope, as indicated by the title, is the measuring methods used to determine package dimensions for small outline packages (SOP). That makes it useful as a technical basis for drawing preparation, dimensional verification, and documented evaluation of package geometry. The edition and original status indicate it serves as the primary reference for this package class.

Applications of IEC 60191-6-21:2010

IEC 60191-6-21:2010 is commonly relevant in semiconductor design, package qualification, incoming inspection, and component specification review. It may be used when preparing or checking outline drawings, comparing supplier data, or confirming that package dimensions are measured in a consistent way across technical review and testing workflows. It is especially useful for organizations involved in surface mount assembly, device integration, and conformity assessment preparation where mechanical compatibility and dimensional clarity affect product selection and manufacturing consistency.

Why IEC 60191-6-21:2010 matters

Clear and repeatable package dimension measurement helps reduce integration risk, supports interoperability across suppliers, and improves the reliability of engineering validation. By defining how small outline package dimensions are assessed, the document can assist quality workflows, procurement review, and compliance documentation with a more consistent technical basis. It also supports laboratory evaluation and verification activities by helping teams use the same dimensional reference logic when comparing parts, checking drawings, or preparing evidence for technical compliance and risk management.
