China Pcb Printed Board Electronic Products 12v Circuit Board With High Quality In Shenzhen
The simplest way of understanding high-frequency PCBs is by getting to know its features, such as:
Little or no delay in high-frequency signal transmission—the dielectric constant (Dk) figure must be small and stable—a lower value for Dk ensures more efficient transmission of high frequencies.
Little or no attenuation of high-frequency signal transmission—the dissipation factor (Df) figure must be small—a lower value for Df ensures low loss and clearer signal transmission.
No damage due to temperature fluctuations—the coefficient of thermal expansion (CTE) of the substrate material must be very close to that of the copper foil on the board—both should contract and expand equally to avoid separation and prevent electrical discontinuity.
No damage due to high temperatures—the glass transition temperature (Tg) must be high—to prevent distortion during high temperatures existing in reflow ovens, especially when undergoing lead-free soldering during assembly.
Appropriate peel off resistance, chemical resistance, water absorption rate, impact endurance, and heat resisting property for the application.
