T1K, T2K, and TSK from TE Connectivity (TE) are very high temperature labels. These white self-adhesives are suitable for identifying components and assemblies that will undergo high temperature processes or environments such as soldering on printed circuit boards (PCB).
Made of polyimide, T1K, T2K, and TSK are suitable for direct wave (bottom side) and IR reflow (top side) PCB applications. These high temperature labels are designed to withstand the fluxes, cleaning solvents, and molten solder encountered in the manufacture of PCBs. All three types are thermal transfer printable and offer excellent contrast, which is helpful when printing or reading bar codes or alphanumeric codes.
“TE’s polyimide T1K, T2K, and TSK labels can survive at elevated temperatures,” said Stephen Earley, Global Product Manager for Identification Systems. “This capability means TE’s polyimide labels are ideal for identifying electronic and electrical components.”
T1K is a low profile 1 mil and popular for manual application on relatively small production runs. It has a gloss white topcoat and will remain in place and legible even after 90 seconds from -40°F to 572°F, five minutes at -40°F to 500°F, or 100 hours from -40°F to 302°F.
T2K is thicker at 2 mil with a gloss white topcoat and can be applied automatically for large batches. It is suited to automation and offers protection against electrostatic discharge (test methods are in accordance with EOS/ESD S11.11). This is important to avoid damaging sensitive electronic components or to minimize the potential for combustion. T2K has a 100 hour service temperature of -40°F to 302°F, a five minute service temperature of -40°F to 500°F, and 90 second service temperature of -40°F to 572°F.
TSK has a high opacity gloss white topcoat and is deemed to be a Static Safe product in accordance with EIA 625, EIA 541. Test methods were in accordance with EOS/ESD S11.11. This static dissipative label is designed to withstands harsh fluxes, cleaners, saponifiers, and wave solder environments. Its temperature rating is -40°F to 302°F for 100 hours, -40°F to 500°F for five minutes, and -40°F to 572°F for 90 seconds.
