Durable, Precise Labels for the Electronics Industry

PCB assembly involves wave soldering (260°C+), reflow soldering (up to 260°C peak), and chemical cleaning with isopropyl alcohol and flux removers. Standard labels cannot survive these processes — they melt, delaminate, or lose adhesion. Nurvyn offers polyimide (Kapton) and high-temperature polyester labels specifically designed to withstand PCB assembly temperatures and chemical exposure. Our polyimide labels maintain full adhesion and print clarity through 260°C peak reflow temperatures and repeated IPA cleaning cycles. We provide material data sheets confirming temperature performance so you can include them in your process validation documentation.

Electronics manufacturers need to track individual units through production, distribution, and field service. Serialized labels with unique identifiers, barcodes, and QR codes are essential for warranty management, recall management, and regulatory compliance. Managing variable data printing at scale — while maintaining 100% accuracy — requires specialized printing systems and verification processes. Nurvyn’s digital printing systems support full serialization with 100% barcode verification before shipment. We can produce labels with sequential serial numbers, lot codes, date codes, and any combination of variable fields. All variable data is cross-checked against your specification file before shipment.

Electrostatic discharge (ESD) can damage sensitive electronic components during handling and assembly. Standard labels can generate static charges that damage components. Nurvyn offers ESD-safe label materials that dissipate static charges, protecting your components throughout the assembly and distribution process. Our ESD-safe materials meet ESD Association standards and are available in white and clear finishes with permanent or removable adhesives. Surface resistance data sheets are available for your ESD control program documentation.

Electronics labels often need to contain a significant amount of information — part numbers, serial numbers, barcodes, safety symbols, voltage ratings, and compliance marks — in a very small space. Maintaining legibility at small sizes requires high-resolution printing and careful design. Nurvyn’s printing systems maintain crisp text and scannable barcodes at very small sizes — down to 6pt text and 0.25mm barcode bar widths. All barcodes are verified with a calibrated barcode verifier before shipment to ensure they meet GS1 quality standards. We can provide barcode quality reports with each shipment for critical traceability applications.

Electronics products sold in major markets require specific compliance marks — UL in the US, CE in the EU, RoHS compliance statements, and others. These marks must be correctly formatted and applied to the correct locations on the product. Incorrect or missing compliance marks can prevent market access and trigger regulatory action. Nurvyn can print UL, CE, RoHS, WEEE, and other compliance marks in the correct format and size for your target markets. For UL-listed products, we can provide labels on UL-recognized materials with the appropriate UL file number. We can advise on the correct formatting requirements for each mark.

Electronics equipment is used in a wide range of field environments — from office environments to industrial facilities, outdoor installations, and harsh industrial conditions. Labels must survive the full service life of the equipment — often 5–10 years or more — while remaining legible and adhered. Nurvyn offers materials with proven long-term durability in demanding field environments. Our outdoor-grade polyester labels maintain legibility for 5–10 years in UV-exposed outdoor installations. Chemical-resistant polyester labels survive repeated exposure to oils, solvents, and cleaning agents used in industrial maintenance. We can provide accelerated aging test data for specific field environment requirements.
