IEC 60191-2Z:2000

Overview

IEC 60191-2Z:2000 is the twenty-fourth supplement to IEC 60191-2 (1966), focusing on the mechanical standardization of semiconductor devices, specifically addressing dimensions. Published by the International Electrotechnical Commission (IEC), this standard is fundamental for ensuring uniform mechanical specifications and dimensions of semiconductor device packages. It supports international cooperation and unification within the semiconductor industry, enabling consistent manufacturing, design interchangeability, and automated handling.

This supplement updates and integrates new drawings and dimensional specifications into the existing IEC 60191-2 publication, maintaining its relevance and compliance with evolving semiconductor device packaging technologies. It is part of a continuous series of supplements (A through Z) that amend and refine the foundational 1966 document.

Key Topics

• Mechanical Standardization Philosophy
  IEC 60191-2Z emphasizes precise definition of semiconductor device dimensions to ensure interchangeability and facilitate automated assembly processes. The standard mandates that all new proposals undergo a thorough review by qualified working groups and require multi-national support before inclusion.

• Device Outline Drawings
  The supplement provides comprehensive updated device outline drawings that define package dimensions, shapes, and outline requirements. These drawings are crucial for designers and manufacturers to comply with internationally recognized mechanical dimensions.
