IEC 62899-401:2025

Overview

IEC 62899-401:2025 provides an authoritative overview of the IEC 62899-4XX series and the modular approach to printability in printed electronics. The document defines scope, key terms and the structure of measurement and compliance parts that establish how to evaluate the interaction of printing plate, ink, substrate and environmental conditions. This edition updates terminology (for example, printing media → printing plate; pattern width → line pattern width; thickness → thickness of printed line) and lists published IEC 62899-4XX documents in the Bibliography.

Key Topics

The standard organizes printability into measurable quality factors and test requirements focused on reproducibility and comparability across manufacturing setups. Major topics include:

• Terms and definitions: clarified definitions for printed electronics, printed pattern, void, basic pattern, surface roughness and surface profile.
• Measurement scope: separation of quality factors into horizontal and vertical elements:
  • Horizontal: length and width, edge waviness, void occurrence and line pattern width.
  • Vertical: thickness of printed line, surface roughness and surface profile.
• Modular series structure: the Part 4XX series covers measurement methods (Part 402-x), reproducibility requirements (Part 403-x), analysis and compliance test methods (Part 404), and environmental measurement methods (Part 405).
• Practical measurement methods: referenced measurement parts include IEC 62899-402-1 (line pattern widths), IEC 62899-402-2 (edge waviness), IEC 62899-402-3 (voids via 2D optical imaging) and TR 62899-402-4 (morphology classification and measurement guidance).
• Reproducibility focus: requirements target both machine and printing plate reproducibility and basic application pattern reproducibility (IEC 62899-403-x series).

Applications

IEC 62899-401:2025 and the IEC 62899-4XX series are practical tools for:

• Manufacturers establishing quality control and acceptance criteria for printed electronics production.
• Test labs and R&D groups developing measurement protocols for pattern fidelity, line width control, defect identification (voids) and surface morphology.
• Procurement and compliance teams specifying reproducibility and environmental test conditions for vendor qualification.
• Industry stakeholders seeking harmonized, internationally comparable metrics to facilitate trade and technology adoption.

The overview helps stakeholders map which part of the modular series applies to specific measurement or compliance tasks without prescribing implementation details beyond definitions and structure.
