Tachyon 100G laminate materials are designed for very high-speed digital applications up to and beyond data rates of 100 Gb/s.

Tachyon 100G materials exhibit exceptional electrical properties that are very stable over a broad frequency and temperature range between -55°C and +125°C up to 100 GHz. These electrical properties provide designers a scalable solution for next generation designs of backplanes and daughter cards, enabling 10x improvements from 10 Gb/s data rates.

Isola has developed Tachyon 100G with the highest level of thermal performance for high layer count line cards. The very low Z-axis CTE makes Tachyon 100G a perfect choice for fine pitch BGA applications of 0.8 mm or less and designs with multiple 2 ounce copper ground planes. Tachyon 100G materials are optimized laminate and prepreg forms that use mechanically spread glass to mitigate skew, improve rise times, reduce jitter, and increase eye width/height and that use ultra smooth VLP2 (2um Rz) copper that significantly reduces conductor losses.
