TDS No. B-496

Effective Date: 29-Jun-2011

Description:

GENERAL

Print Technology: Thermal Transfer

Material Type: White Polyimide (2 mil film)

Finish: Glossy

Adhesive: Permanent Acrylic

APPLICATIONS

Printed circuit board and electronic component preprocess labeling, especially with auto-dispensing requirements

RECOMMENDED RIBBONS

Brady Series R6000

Brady Series R6000HF

REGULATORY/AGENCY APPROVALS

UL: B-496 is a UL Recognized Component when printed with the Brady Series R6000 and Series R6000HF ribbons. See UL files PGJI2.MH17388 and PGJI2.MH17154 for specific details. UL information can be accessed online at UL.com.

Brady B-496 is RoHS compliant to 2005/618/EC MCV amendment to RoHS Directive 2002/95/EC.

SPECIAL FEATURES

The B-496 is designed for auto-dispensing with Brady's PAM (Printer Applicator Machine) and with Hover Davis label dispensing machines.

The B-496, in combination with the Series R6000 and Series R6000HF ribbons, meets the requirements of MIL-STD-202G, Method 215K and SAE AS81531 Marking of Electrical Insulating Materials.

Preheat can be employed to further enhance print permanence in the case of extreme solvent and/or abrasion exposure, although this is not typically required for board processing applications.
