Overview
IEC 60748-22:1997 is an international standard developed by the International Electrotechnical Commission (IEC) that specifies sectional requirements for film integrated circuits (FICs) and hybrid film integrated circuits (HICs). This standard focuses on the capability approval procedures used to assess the quality and reliability of these semiconductor integrated circuits, whether manufactured as catalogue items or custom-built solutions. It plays a crucial role in defining preferred ratings, characteristics, test methods, and general performance criteria to be used in detailed specifications.
The document reflects current technological practices as of its 1997 revision and provides a comprehensive framework for manufacturers and quality assurance bodies to ensure consistent performance and quality in film and hybrid film integrated circuits.
Key Topics
