As data rates move beyond 56Gbps PAM4 and toward 112Gbps, traditional PCB materials struggle to maintain signal integrity. Loss budget becomes the bottleneck—not routing or topology.
That’s where ITEQ IT-968SE comes in.
From an engineering standpoint, this material sits in a sweet spot:
Lower loss than mid-tier FR-4 derivatives
More cost-effective than PTFE or Megtron 7
Compatible with standard PCB fabrication processes
The result: a practical, production-ready laminate for high-speed digital and RF designs.
Why 56Gbps+ Designs Demand Better Materials
At 56Gbps PAM4:
Nyquist frequency ~14 GHz
Channel insertion loss becomes critical
Skin effect + dielectric loss dominate
Standard FR-4 simply cannot keep up:
Df ~0.015–0.020 → excessive attenuation
Poor Dk stability → impedance drift
By contrast, ITEQ IT-968SE offers ultra-low loss (Df < 0.004 @ 10GHz)hemeixinpcb.com
This is the key enabler for:
Long backplane channels
High-speed connectors
Reduced need for retimers

Electrical Performance Deep Dive
1. Dielectric Constant (Dk)
ITEQ IT-968SE maintains stable Dk across frequency:
Frequency
Dk
1 GHz
~3.4
5 GHz
~3.35
10 GHz
~3.34
Low Dk reduces:
Signal delay
Crosstalk
2. Dissipation Factor (Df)
Frequency
Df
1 GHz
~0.0027
5 GHz
~0.0035
10 GHz
~0.0038
This ultra-low loss is critical for:
Backplane >30 inches
56G SerDes links
Lower Df = lower insertion loss = cleaner eye opening.
3. Signal Integrity (SI) Advantage
From a PCB engineer’s perspective:
Stable Dk/Df → easier simulation
Predictable impedance → fewer tuning iterations
Reduced equalization requirements
