Why choose High Speed PCB?

Key Parameters of High-Speed PCB Materials

Critical specifications for optimal signal integrity

Dielectric Constant (Dk)

Target Range: 2.2 – 4.5
Stability: <1% @10GHz
  •  Reduces signal delay
  •  Minimizes phase distortion
  •  Rogers materials excel

Loss Tangent (Df)

High-Speed Target: <0.005
Example: RO4003C: 0.0027
  •  Minimizes energy loss
  •  Critical for signal integrity
  •  Impacts high-frequency performance

Glass Transition (Tg)

Automotive Grade: >170°C
Premium Example: I-Tera MT40: 210°C
  •  Prevents delamination
  •  Essential for harsh environments
  •  Higher Tg = better reliability

CTE (Z-axis)

Critical Threshold: <50ppm/°C
Copper Matching: Essential
  •  Prevents via cracking
  •  Reduces thermal stress
  •  Key reliability factor
