HF – High Frequency printed circuit boards

PCB Express is your experienced partner for production of high frequency (HF) printed circuit boards. HF (High Frequency) PCBs, also known as HF-PCBs or High-Frequency printed circuit boards, are used for applications that require high signal frequencies or fast signal transmissions. These PCBs are specially designed to meet the requirements of the high-frequency range (usually above 500 MHz up to the GHz range).

When PCB becomes more and more complex, certain characteristics of the laminate will play a major role in how the various circuit layers can be aligned:

• Dimensional stability
• Low Z-axis expansion
• Low in-plane expansion coefficient
• Low thermal coefficient of dielectric constant

The materials we use have requested characteristics required for High Frequency printed circuit boards:

• High frequency performance due to tight dielectric tolerance and low loss
• Stable electrical properties versus frequency
• RoHS compliant, environmentally friendly

Coefficient of Thermal Expansion (CTE)

• The linear change in dimension as a function of temperature.

PCB Express provides you with expertise and qualified manufacturing processes - reliable even for complex requirements.
