TLY-5 2-Layer 10mil High-Frequency Thin PCB with Immersion Gold

1.Introduction

TLY-5 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-5 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.

2.Key Features

Dielectric constant of 2.2 with tight tolerance 0.02 at 10 GHz/23°C
0.0009 loss tangent at 10GHz
Density (specific gravity) of 2.19 g/cm³
