High Frequency PCB Manufacturer | Suntech Electronics

1.Low-loss dielectric materials 
 • Materials like Rogers, Taconic, Nelco, or PTFE (Teflon) are used instead of standard FR-4. 
 • These materials minimize signal loss and maintain consistent dielectric constant (Dk). 
2.Controlled impedance 
 • Signal traces need precise widths, spacing, and layer stackup to control impedance, reducing reflections and signal degradation. 
3.Low dielectric constant (Dk) and low dissipation factor (Df) 
 • Low Dk keeps signals fast and consistent. 
 • Low Df reduces energy loss in the PCB at high frequencies. 
4.Thin copper layers and smooth surfaces 
 • Reduce conductor losses and signal scattering. 
 • Surface roughness of copper can increase losses at GHz frequencies. 
5.Minimized via inductance 
 • High-frequency signals are sensitive to vias; designers often use back-drilled or filled vias to reduce parasitic inductance. 
6.Proper ground and shielding 
 • Essential for EMI control. 
 • Microstrip or stripline configurations are commonly used.
