Solution Spotlight: B-734 White Matte Electrostatic Dissipative (ESD) Laser Markable Polyimide

The Challenge

PCB assembly

Barcode or alphanumeric identification that meets crisp resolution requirements and withstands extreme environments for printed circuit board and electronic component manufacturing and assembly. Other requirements:

  • Non-sooting white laser markable label
  • Compatible with auto-dispensing applications

The Solution

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 no-soot option that can withstand high temperatures, harsh chemicals and environment production processes. 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

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

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

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

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

RoHS compliant

RoHS compliant to RoHS Directive 2011/65/EU
