Overview
The IEC 60191-2Y:2000 standard, published by the International Electrotechnical Commission (IEC), serves as the twenty-third supplement to the original IEC 60191-2 standard from 1966. This document focuses specifically on the mechanical standardization of semiconductor devices, with an emphasis on the dimensions of these devices. It aims to provide a comprehensive framework and unified terminology for defining and standardizing the physical dimensions and outlines of semiconductor components globally.
IEC 60191-2Y is a key resource for manufacturers, designers, and quality engineers involved in semiconductor device development, ensuring interchangeability, compatibility, and streamlined automatic handling in production environments. The standard is essential for mechanical drawings, case outlines, and packaging dimensions of various semiconductor devices.
Key Topics
-
Mechanical Standardization Philosophy
The standard establishes fundamental principles for collaborative and active standardization, emphasizing international support for device outlines and intercultural cooperation through IEC committees. It encourages continuous review and removal of obsolete device outlines to maintain a current and relevant body of standardized designs.
-
Device Outline Drawings
Detailed guidelines for drawings that define physical dimensions of semiconductor device packages. These drawings promote consistent device outlines facilitating easy identification and interchangeability.
-
Package and Base Drawings
Dimensions for device packages and their bases are standardized to improve manufacturing efficiency and ensure interchangeability between devices from different manufacturers.
-
Code Associations
The standard links device outlines with national and international codes, enabling uniform identification and supporting global supply chains.
-
Obsolete Drawings Management
Protocols for removing or archiving device outlines that are no longer supported by multiple countries, preventing outdated designs from causing confusion in industry applications.
-
Supplement Integration and Updates
This supplement updates previous pages and drawings in IEC 60191-2, ensuring the standard remains current with evolving semiconductor packaging technologies and global industry demands.
