Color Polyimide Labels for RoHS/WEEE Compliant and Standard Processes

"Polyonics Inc. introduces 1 & 2 mil color polyimide labels. These color polyimide labels are coated with a permanent pressure-sensitive acrylic adhesive and a high opacity, medium gloss topcoat available in 6 tinted colors - pink, yellow, orange, blue, green and violet. They are thermal transfer printable and scan with both visible and IR scanners. Barcode labels made from these colored polyimide materials demonstrate excellent performance in lead-free wave solder environments, which range from 260° to 290°C. Polyonics developed this series of colored polyimide labels, which will survive both standard and lead-free processes on top or bottom side of the board, for manufacturers looking to color code production/process lines. For instance, most manufacturing companies will run parallel production lines as they transition to lead-free processes resulting in two product streams - RoHS/WEEE compliant and non-compliant. Some companies choose to use the plain white polyimide labels for standard "non-compliant" subassemblies, and a color-coded label (e.g., pink, yellow, orange, blue, green or violet) for the compliant products. Using these color-coded labels will allow manufactures to tell at a glance those that are compliant subassemblies from those that are non-compliant." Source: emsnow.com
