IEC 60194-1:2021

Overview

IEC 60194-1:2021 is an international standard published by the International Electrotechnical Commission (IEC) that defines the vocabulary commonly used in printed boards design, manufacture, and electronic assembly technologies. This is Part 1 of the vocabulary series covering common terms closely related to TC91 technology. It replaces the earlier IEC 60194:2015 edition alongside IEC 60194-2:2017, offering a technical revision with updated terminology reflecting current industry trends.

This standard is essential for professionals involved in the printed circuit board (PCB) and electronic assembly sectors. It ensures consistent communication and understanding across global manufacturers, designers, and quality specialists by providing clear, standardized definitions relevant to the electronic assembly industry.

Key Topics

• Comprehensive Terminology: The document organizes terms alphabetically (A to Z), covering detailed vocabulary for design, fabrication processes, assembly techniques, and materials related to printed boards.
• Updated Content: IEC 60194-1:2021 excludes outdated or irrelevant terms, improves clarity by removing identification codes, and introduces:
  • 14 new terms related to device embedded substrate technology.
  • 113 synonymous terms to standardize alternative expressions.
• Technical Illustrations: The standard includes numerous figures to visually represent concepts such as access holes, alignment marks, buried vias, soldering types, and defects like barrel cracks or bowing.
• Industry Relevance: The revisions cater to the evolving technologies in PCB manufacturing and assembly, ensuring the vocabulary remains aligned with current practices and innovations.
• Harmonization: By cancelling and replacing previous editions, the standard promotes uniformity and simplifies integration with other technical documents and manufacturing guidelines.

Applications

IEC 60194-1:2021 is valuable across the entire lifecycle of PCB development and electronic product manufacturing:

• Design Engineers: Use the standardized vocabulary to specify and communicate design requirements, constraints, and manufacturing expectations clearly.
• Manufacturers: Implement consistent terminology in process documentation, quality control, and production training, ensuring alignment with global industry standards.
• Quality Assurance: Utilize precise definitions for inspection criteria, defect recognition, and compliance verification to improve product reliability and reduce errors.
• Technical Documentation: Authors of datasheets, user manuals, and regulatory submissions benefit from consistent term usage to enhance clarity and professionalism.
• Training & Education: Serves as an authoritative reference for academic curricula and workforce training programs in electronics manufacturing and assembly.

Related Standards

IEC 60194-1:2021 should be considered in conjunction with several related IEC and international standards to fully cover PCB and electronic assembly technologies:

• IEC 60194-2:2017 – Complements Part 1 by covering detailed and advanced terminology.
• IEC 60194:2015 – The superseded edition now replaced by Parts 1 and 2.
• Other IEC TC91 standards – Cover broader aspects of circuit boards, including testing methods, requirements, and environmental considerations.
• IPC Standards (e.g., IPC-A-600, IPC-2221) – Widely adopted guidelines for PCB fabrication, design, and inspection that align with IEC vocabulary.

By adhering to IEC 60194-1:2021, stakeholders in printed circuit board design and electronic assembly ensure consistent and precise language usage, fostering clear communication and enhancing interoperability across international markets. Its comprehensive and updated terminology supports innovation and quality improvements in the rapidly evolving electronics manufacturing industry.
