2d-matrix
Data Matrix (ECC 200) (Data Matrix)
Extremely compact 2D matrix symbology widely used for small electronics direct-part-marking (DPM), aerospace, and industrial component tracking.
Governing Specification: ISO/IEC 16022:2006
Data Format & Required Fields
Uses Reed-Solomon error correction (ECC 200) with L-shaped finder pattern and alternating clock tracks on opposing boundaries.
Allowed Character SetFull ASCII (0-127) and extended byte values (128-255).
Payload Length Rule Between 1 and 2335 characters
Example Valid Format
PRX-PART-99482-REV-CIndustry Guidance & Practical Applications
- Printed circuit board (PCB) and microchip marking
- Aerospace parts identification (ATA Spec 2000)
- Automotive asset tracking
Packaging & Scanning Notes: Standardized by ANSI/ISO. Supports text, raw binary, and ASCII data.
Symbol Constraints & Label Guidelines
- Requires 2D area imager for optical capture.
- Sub-millimeter DPM laser etching requires high-contrast surface finishing.
