IEC 60191-2:1966/AMD4:2001 provides a supporting update to Mechanical standardization of semiconductor devices - Part 2: Dimensions, helping users apply a revised dimensional reference within semiconductor device documentation, engineering review, and conformity assessment workflows. As an amendment to IEC 60191-2:1966, it should be read as a modifying document rather than a standalone technical basis. For teams managing product evaluation, procurement checks, or technical validation, IEC 60191-2:1966/AMD4:2001 is relevant where consistent device dimensions and controlled document use are important.

What is IEC 60191-2:1966/AMD4:2001?

IEC 60191-2:1966/AMD4:2001 is Amendment 4 to the parent document IEC 60191-2:1966, focused on the mechanical standardization of semiconductor devices with emphasis on dimensions. In practical terms, it is used to update or refine dimensional references that engineers, manufacturers, and compliance teams may rely on when comparing package geometry, preparing technical documentation, or checking design alignment. Because it is an amendment, its value lies in modifying the parent specification within engineering and documented evaluation processes.

Applications of IEC 60191-2:1966/AMD4:2001

This document is most relevant in semiconductor design, component procurement, drawing control, and laboratory evaluation where dimensional consistency must be maintained across part selection and verification activities. It may support technical review of device packages, specification matching, and quality workflows that depend on reliable mechanical references. Organizations involved in product evaluation or conformity assessment can use IEC 60191-2:1966/AMD4:2001 to track the applicable amendment status of the parent dimensional standard and reduce ambiguity in engineering documentation.

Why is IEC 60191-2:1966/AMD4:2001 important?

Dimensional standardization helps reduce integration risk, supports interoperability between devices and assemblies, and improves consistency during inspection and verification. IEC 60191-2:1966/AMD4:2001 is important because it helps ensure that the parent mechanical dimensions are interpreted with the correct amendment context, which is essential for compliance workflows, procurement review, and technical validation. Using the correct supporting reference can also strengthen quality assurance, lower the chance of drawing mismatches, and improve documentation control across engineering teams.

• Supports dimensional reference control for semiconductor device documentation
• Useful for engineering review, drawing checks, and package comparison activities
• Helps maintain amendment traceability within compliance and procurement workflows
• Relevant to quality assurance and conformity assessment preparation
