Definition

Tachyon 100G is Isola's premium ultra-low-loss laminate targeting 100 Gbps and beyond. Dk is exceptionally stable at 3.02-3.04 across 2-10 GHz, and Df reaches 0.0021. Tg of 215°C (DSC) and thermal stability (T260/T288/T300 all exceed 60/60/20 minutes) make it robust for demanding assemblies. The material is compatible with HVLP3 copper foil (≤1.1 µm Rz) for minimum conductor loss at extreme speeds. Available with low-Dk glass, square weave, and mechanically spread glass constructions to minimize fiber weave effect. Performance is validated to 100 GHz. Use Tachyon 100G for backplanes, fine-pitch BGA breakout, and 112 Gbps PAM4 designs where Megtron 7/8 is the alternative.
