The shrinking printed circuit board, paired with the desire to add more information to barcode labels used for product traceability, has introduced a new challenge — the need for a small barcode label that remains decodable at the smallest of font sizes.

The barcode or alphanumeric identification must also be able to:

Withstand the extreme environments for printed circuit board and electronic component manufacturing and assembly
Be laser marked without creating soot
Be compatible with auto-dispensing applications

Brady B-734 matte white laser markable polyimide material is a non-sooting option ideal for difficult-to-survive conditions, including high-temperature reflow steps for surface-mount technology and washing steps that limit the use of traditional thermal heat transfer print.

Our laser markable labels, which includes B-734, are designed to withstand high temperatures, harsh chemicals and environment production processes making them the most durable, permanent label identification in the entire Brady portfolio.

Technical Data Sheet: Brady B-734 Matte White ESD Laser Markable Polyimide

Key performance attributes:

Abrasion resistance

Tested using Taber Abraser equipment with CS-10 grinding wheels and weighted arms. No effect to label or printed image after 100 cycles.

High heat resistance

Resistance to 266°F (130°C). Labels were subjected to a range of temperatures for 1,000 hours with only a very slight discoloration of the label and no visible effect to the printed image, while label remains functional.

Low temperature resistance

Labels subjected to -94°F (-70°C) for 1,000 hours with no visible effect, while label remains functional.

Adhesion capabilities

Adheres to stainless steel and epoxy PC board.

Regulatory and agency approvals:

UL Recognized to UL969 Labeling and Marking Standard when marked with an infrared laser

RoHS compliant to RoHS Directive 2011/65/EU
