IEC 60191-2X:1999

Overview

IEC 60191-2X:1999 is an international standard published by the International Electrotechnical Commission (IEC) that focuses on the mechanical standardization of semiconductor devices, specifically their dimensions. This document is the twenty-second supplement to the original IEC 60191-2 published in 1966, incorporating updates and corrigenda up to January 2000.

The standard ensures uniformity in the mechanical dimensions of semiconductor device packages, supporting international interoperability, quality control, and automated handling. It details recommended values for dimensions, device outline drawings, and mechanical design philosophies to create a consistent framework for semiconductor package design worldwide.

Key Topics

• Mechanical Standardization Philosophy
  The standard outlines fundamental rules for mechanical standardization to ensure interchangeability, precise dimensioning, and global acceptance of semiconductor device outlines. It prioritizes international support for package types, continuous review of existing standards, and the removal of obsolete designs.

• Device Outline Drawings
  The document provides comprehensive device outline drawings with exact dimensional specifications. These drawings serve as templates to manufacture packages to exact mechanical tolerances.

• Package Types and Dimensions
  It covers a wide range of commonly mounted semiconductor device packages, specifying dimensions critical for compatibility and automated assembly.

• Base, Case, and Gauge Drawings
  The standard includes detailed base drawings, case outlines, and gauge designs to complement the device outlines and ensure complete mechanical standardization across all semiconductor packages.

• Obsolete and Updated Drawings
  IEC 60191-2X designates obsolete drawings separately, along with timelines for their removal, supporting efficient update and maintenance of current industry standards.

• National Code Integration
  The standard integrates national codes representing different countries' support, enabling global consensus and traceability in semiconductor packaging.

Applications

• Semiconductor Device Manufacturing
  Manufacturers utilize IEC 60191-2X for designing and producing semiconductor packages with standardized dimensions to ensure compatibility with automated assembly lines and testing equipment.
