Polyonics introduces 1 and 2 mil color polyimide labels. The labels are
coated with a permanent pressure-sensitive acrylic adhesive and a high
opacity, medium gloss topcoat available in six tinted colors ¾ pink,
yellow, orange, blue, green and violet. They are thermal transfer
printable and scan with both visible and IR scanners. Barcode labels
made from the materials reportedly demonstrate excellent performance in
lead-free wave solder environments, which range from 260º to 290ºC.
Designed
for barcode or alphanumeric identification of PCBs or electronic
components, can withstand mixed circuit board processes, on either the
top or bottom side of the board. Said to have excellent resistance to
harsh fluxes, cleaning agents, saponifiers and wave solder
environments, and resist common methods of cleaning.
Polyonics
developed the 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. 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.
