Automatic Direct Part Mark Identification (DPMI) has been made possible by the emergence of machine readable Data Matrix codes. A Data Matrix code is a two-dimensional (2D) symbol. Conventional one-dimensional (1-D) barcodes are widely used in many retail and industrial applications today. However, conventional barcodes have some inherent limitations, which prevent their use in identifying and tracking products as they are manufactured.
The main benefits of using Data Matrix for DPMI are:
- Higher data density
- Fast direct marking without labels
- Small space requirements
- Scalable size
- Omni directional
- Suitable for low contrast reading
- Increased data integrity
- Less precise, high-contrast printing requirements
- Robustness to extreme environments
- Suitable for safety critical parts
- Standard in public domain
Data Matrix codes are usually permanently marked on products by using dot peen/ pin-stamp, laser or electro chemical etching machines. Reading a 2D code in DPMI applications requires taking a picture of a code that's marked directly on a part and analyzing that image to extract data from the code. The data could tell you the part's production date, the lot number or batch, or the manufacturer's serial number.
The main drivers for Direct Part Marking are:
- Error proofing
- Part cradle-to-grave traceability
- Part unit level traceability
- Improved process control
- Part authenticity
- Supply chain management
- Improved quality control
- Industry regulatory requirements
DPM has found extensive use in automotive, aerospace, electronics, semiconductor, medical devices and other manufacturing unit-level traceability applications.
