Data Matrix Polyimide Labels for PCB identification
- Data Matrix ECC200 code encodes high data density in a compact square symbol
- Polyimide base film rated for continuous and peak service to 260 °C
- Survives lead-free SMT reflow without code degradation or delamination
- White-coated polyimide face provides high print contrast for reliable 2D scan rates
- Supports very small label formats — critical for space-constrained PCBs
Features of Data Matrix Polyimide Labels for PCB identification
Data Matrix Polyimide Labels for PCB Identification address one of the most demanding intersections of electronics traceability requirements: the need to encode a substantial amount of identification data — serial numbers, lot codes, date codes, and part numbers — into a very small label footprint that can be placed on an increasingly compact PCB, and that will remain scannable after passing through SMT reflow ovens at temperatures up to 260 °C.
Data Matrix ECC200 is the preferred 2D symbology for this application because its square cell structure allows the same data capacity as a Code 128 barcode in approximately one-tenth of the label area, and its built-in Reed-Solomon error correction allows reliable reading even if up to 30% of the code symbol is damaged.
- VIZLENT prints Data Matrix Polyimide Labels for PCB Identification on white-coated polyimide film using resin thermal-transfer ribbon, which provides the combination of thermal stability and print durability required for the complete SMT assembly workflow.
- The white coating on the polyimide face dramatically improves Data Matrix contrast compared to printing directly on amber polyimide, directly improving first-read scan rates in automated assembly and test equipment.
- The silicone adhesive system bonds firmly to FR-4 and related PCB substrates while remaining non-flowing and non-contaminating at peak reflow temperatures, protecting the integrity of adjacent solder joints and optical components.

Frequently Asked Questions
Data Matrix ECC200 can encode alphanumeric strings, GS1 Application Identifiers (serial numbers, lot numbers, date codes, part numbers), and custom data strings up to several hundred characters depending on the matrix size and module size selected. VIZLENT accepts a customer-supplied data file or numbering scheme and encodes it during factory printing. We can also incorporate human-readable text alongside the Data Matrix symbol so that the label serves both machine-scanning and manual-inspection purposes.
Yes, provided the labels are printed with a resin-type thermal-transfer ribbon on white-coated polyimide film, which is VIZLENT’s standard specification for these labels. Resin ribbon print is thermally stable at reflow temperatures and does not smear, carbon, or lose contrast during the soldering process. Post-reflow, the Data Matrix symbol can be read by standard 2D imagers and DPM readers. We recommend customers verify first-read scan rates on sample labels through their specific reflow profile as part of process qualification before volume production.
The minimum practical label size depends on the data content, the Data Matrix version (matrix size), and the module (cell) size, which must be sufficient for reliable reading by the scanner used in the customer’s process. For a short serial number encoded at a Data Matrix version that produces a small matrix, VIZLENT can produce labels as small as approximately 6 × 6 mm, though we recommend consulting with our technical team and verifying scan reliability with your specific reader before committing to a minimum size. We provide sample labels at candidate sizes for customer evaluation.
Reliable Data Matrix scanning — particularly by fixed-beam automated scanners in SMT and test equipment — depends on sufficient print contrast between the dark cells and the background of the symbol. Standard amber polyimide film has a golden-brown colour that reduces contrast when printed with black thermal-transfer ink, resulting in lower first-read scan rates and higher error rates in automated scanning. White-coated polyimide provides a white background that maximises contrast while retaining the full thermal performance of the polyimide base film, giving the best of both properties for PCB Data Matrix labelling.
Yes. This is VIZLENT’s standard workflow for Data Matrix Polyimide Labels for PCB Identification. Customers supply a data file in CSV, Excel, or plain-text format containing the exact serial numbers, lot codes, or other variable data to be encoded, along with any fixed content (part number, company name, revision). We generate the Data Matrix symbols from your data, produce a pre-production proof for approval, and ship finished rolls with labels in the correct sequence for direct application to your production line without any in-house printing requirement.
