Overview
IEC 62899-403-2:2026 is an international standard developed by the International Electrotechnical Commission (IEC) that defines the basic requirements for assessing the reproducibility of printed patterns in printed electronics by evaluating the quality of printing plates. This standard is especially relevant for industries involved in gravure, relief (flexo), offset, rotary printing cylinders, and screen printing mesh masks. It specifically excludes inkjet printing technologies from its scope.
IEC 62899-403-2:2026 details a set of standardized basic patterns that facilitate consistent evaluation of how well printing plates transfer high-precision micro-patterns required for the fabrication of electronic circuits and components. The adoption of this standard promotes international uniformity in printability assessments for printed electronics manufacturing.
Key Topics
-
Basic Patterns for Evaluation: The standard provides five series of two-dimensional graphical patterns designed for reproducibility testing:
- Lines with even width and space
- Lines with varying widths
- Lines with varying space between lines
- Radial lines pattern
- Tilted lines and space patterns
- Right-angled line patterns
-
Printing Plate Types: Covers all major traditional methods used in printed electronics, including gravure, flexography, offset printing, rotary cylinders, and screen printing masks.
-
Measurement and Reporting: Specifies parameters for pattern dimensions, layout, and reporting requirements, ensuring clear communication between suppliers and customers regarding the results of printability evaluations.
-
Use Cases: Includes practical examples and error analysis for identifying issues such as dimensional inconsistencies, ink pooling, and the relationships between printing plate quality and final printed results.
-
Agreement on Evaluation Methods: Emphasizes the importance of mutual agreement between suppliers and customers on the patterns, measurement methods, and evaluation criteria to ensure reliable and comparable assessment outcomes.
Applications
IEC 62899-403-2:2026 is vital for:
- Quality Control of Printed Electronics: By implementing standardized basic patterns, manufacturers can reliably assess the fidelity and reproducibility of fine patterns critical for components like sensors, circuits, and conductive traces.
- Printing Plate Evaluation: Enables engineers and inspection personnel to detect and analyze specific defects or inconsistencies linked to the design and manufacture of printing plates using a uniform approach.
- Process Optimization: Data collected using these patterns supports refinements in printing processes, ink formulations, and substrate compatibility to enhance overall printed electronics quality.
- Supplier-Customer Alignment: Clear measurement and reporting protocols help suppliers of printing plates and manufacturers align on quality expectations and troubleshooting procedures, supporting more efficient international trade and supply chain management.
By using the patterns and methodologies defined in this standard, organizations can establish traceable and repeatable quality assessments, reducing variability in high-volume production environments and ensuring compatibility with global supply chain requirements.
