Tachyon®-100G Low-loss Laminate Material For High-speed Digital Applications

Tachyon®-100G Low-loss Laminate Material For High-speed Digital Applications Description:

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

Tachyon 100-G materials exhibit exceptional electrical properties that are very stable over a broad frequency and temperature range.

Tachyon-100G is suitable for scaling current products to their next generation through design of new backplanes and daughter cards, enabling almost 10x improvements from 10 Gb/s data rates. Tachyon-100G targets line cards that require the highest thermal performance. It has identical electricals as Tachyon, but offers a 30% improvement in Z-axis CTEs on high-layer count PCBs. This makes it a perfect choice for higher layer line cards that have multiple 2 Oz. planes and BGAs with pitches at 0.8 mm or less.

Tachyon-100G products use spread glass and reduced profile copper to mitigate skew and improve rise times, reduce jitter, increase eye width and height. Use of ultra smooth cooper is enabled by very high adhesive bond between the resin and the metal. Tachyon-100G has a nominal dielectric constant (Dk) of 3.02 that is stable between -55°C and +125°C up to 40 GHz. In addition, Tachyon-100G offers a very low nominal dissipation factor (Df) of 0.0021.

Tachyon-100G laminate materials are available in optimized laminate and prepreg forms in typical thicknesses and standard panel sizes to provide a complete material solution for high-speed digital multilayer backplanes and daughter cards.

Tachyon Field Testing Highlights:

• Tachyon was used successfully to build multiple homogenous and hybrid high-layer count backplanes:
  • 36-layer 24” X 36” x 0.300” that passed 6X TS at 288°C and 6X at 260°C reflow
  • 36-layer 18+18 sequential laminated backplane
  • 28-layer 16”x18” x 0.300” backplane
  • 34-layer 24” x 21” x 0.280” hybrid backplane with four 4/4 oz. copper cores of 370HR.
  • 36-layer 24” X 28” 0.247” backplane with four 3/3 oz. copper cores
• Tachyon was successful on a number of signal integrity TVs:
  • Speeding Edge 16-layer TV: Tachyon had an insertion loss of 0.849 dB/in. at 16 GHz on a 0.004” wide line that was 8” long line. This is 35% better loss than Panasonic's Megtron-6 with HVLP copper on the same TV.
  • Storage OEM’s internal serpentine SI TV - Tachyon had an insertion loss of 0.621 dB/in. at 12.5 GHz on a 20” line. This was 26% better than Panasonic's Megtron-6 with HVLP copper on the same TV.
  • Infrastructure OEM - Tachyon had an insertion loss of 0.605 dB/in. at 12.5 GHz on a 0.005” wide line that was 20” long.
  • SET2DIL - Tachyon had an insertion loss of 0.27dB/in at 4 GHz on a 0.0065” wide line.
