Reliable and secure marking of printed circuit boards
PCB labels withstand extreme temperature spikes during soldering and ensure traceability during production. They are also exposed to heat sources such as hot air, infrared, and steam. The PCB labels are extremely robust and resistant to cleaning processes involving hot and aggressive chemicals, as well as high-pressure and ultrasonic technology, which are used to remove solder flux residues.
If necessary, they can also be re-labeled with custom data directly at the customer’s site. The labels are tailored to customer-specific requirements and applications and are often used for the identification, traceability, control, and management of materials and products through coding.
Characteristics of Printed Circuit Board Marking
- High resistance to extreme temperature spikes and contact with aggressive cleaning chemicals
- Electrostatic-dissipative adhesive
- High dimensional stability and reliable readability
- Custom die-cutting available—tailored to the PCB structure
- Colored label films offer additional identification options
- High abrasion resistance with compatible thermal transfer ribbons for thermal transfer printing
- Suitable for standards-compliant labeling, such as UL/CSA, etc.
- Very high adhesive strength of the labels, even on challenging substrates such as rough surfaces
- Process optimization through automation of material and product flow
- Additional security features, such as security die-cuts, are possible
- Numerous specialty materials from Avery, 3M, Flexcon, and Tesa available from stock
- Unprinted labels in custom sizes and special shapes
- Suitable for application around corners and edges
Suitable for bonding around corners and edges
Labels designed for the extremely high temperatures encountered in printed circuit board manufacturing offer maximum flexibility and are customized to meet specific customer requirements. This is achieved through the use of suitable specialty materials from leading manufacturers, custom die-cuts, and high-quality adhesives.
The labels can be reprinted on-site in variable quantities with up-to-date data as needed, eliminating the need to stock and manage large numbers of labels.
The printed circuit boards to be labeled are still hot when the labels are to be applied, for which specially formulated adhesives are available.
Our high-quality and meticulous workmanship, combined with state-of-the-art die-cutting technologies, guarantees the highest precision and reliability when using the labels. Even labels with adhesives that are difficult to process can thus be easily processed further by machine, thereby increasing user efficiency in the long term.
Special Features of Printed Circuit Board Marking
Labels for printed circuit boards can withstand temperatures up to +300° C and feature an electrostatic-dissipative adhesive. Temperatures of up to 300° Celsius are reached in printed circuit board manufacturing or during melting and soldering processes. Through the use of specialized printing processes in combination with specialized adhesives, these labels can withstand extreme temperatures of up to +300° C, depending on the application.
Even surfaces that are difficult to label can be covered using different application weights of specialized pressure-sensitive adhesives. Composite materials, adhesive-free zones, and partially pre-printed areas and logos are also possible.
When peeling a label off the backing material, an electrostatic charge may build up on the adhesive. When this charge is discharged, a brief electrical current is generated that can damage sensitive electronic components. Labels for printed circuit boards are manufactured using an electrostatic-dissipative adhesive. This ensures that the label is no longer charged when applied.

Certifications for Printed Circuit Board Marking
Automotive standards and regulations are particularly important for labels on printed circuit boards. Likewise, labels for printed circuit boards intended for the U.S. market must be UL-certified. As a manufacturer, Robos-labels offers a wide range of pre-approved and certified label solutions. If additional customer-specific approvals are required, we can handle the testing and certification process upon request.
In addition, we cover PPF sampling (Production Process and Product Approval) in accordance with the specifications of the German Association of the Automotive Industry (VDA), as well as its American counterpart, PPAP sampling (Production Part Approval Process) from the AIAG (Automotive Industry Action Group).
- UL 969 – Marking and Labeling Systems
The most important standard for permanent labels on electrical and electronic products. Evaluates the durability of the material, adhesive, and print. - UL Recognized Component (e.g., PGJI2 / PGDQ2)
Indicates that the label material used is part of a UL-recognized material system. - RoHS (2011/65/EU, including amending directives)
Restricts hazardous substances in electrical and electronic equipment. Labeling materials must also meet these requirements. - REACH Regulation (EC 1907/2006)
Regulates the use of substances of very high concern (SVHC) in materials and products. - IPC-1782 – Traceability Standard
Defines requirements for the traceability of electronic assemblies and components. Labels with barcodes or Data Matrix codes are a key component of implementation.
