Taconic TLY-3 DK2.33 Df0.0012 (0.09-1.52mm) Copper Clad Laminate
Brief Introduction
TLY-3 laminates are manufactured with very lightweight woven fiberglass and are much more dimensionally stable than chopped fiber reinforced PTFE composites. The woven matrix in the TLY-3 material yields a more mechanically stable laminate that is suitable for high volume manufacturing. The low dissipation factor enables successful deployment for automotive radar applications designed at 77 GHz as well as other antennas in millimeter wave frequencies. Comparative OEM testing at 77 GHz has shown equivalent insertion losses/dielectric properties compared to chopped fiber reinforced competitors, with the primary benefit being much higher manufacturing yields. TLY-3FF is a highly flexible variant designed for applications requiring installation with a bend radius, offering flexibility comparable to chopped fiber reinforced PTFE laminates but with a lower loss tangent, along with the dimensional stability typical of standard fiberglass reinforced laminates.
