Features of The KB-6165 PCB Material
Mid-Tg value
The Mid-Range Glass Transition Temperature (Tg) exceeding 150°C is a cornerstone feature. This ensures the KB-6165 laminate maintains dimensional stability and mechanical integrity under higher operating temperatures and during demanding lead free assembly processes (compatible with lead free soldering profiles).
Dielectric Constant (Dk)
With a dielectric constant (DK 4.6 @1GHz), the dielectric constant of the material is a measure of its ability to store electrical energy in a capacitor like manner. KB-6165 laminates offer a stable Dk, this property measures a material’s ability to store some electrical energy in a given electric field.
Dissipation Factor (Df)
With a dissipation factor (DF 0.016 @1GHz) translates to reduced dielectric loss, ensuring minimal heat generation during signal transmission, which are essential for maintaining signal integrity and low power loss in both digital and analog circuits.
Lead-Free Compatibility
Designed to meet the requirements of RoHS and lead free assembly, the KB-6165 can withstand the elevated temperatures of modern reflow soldering techniques without compromising performance or reliability.
Excellent Thermal Reliability
The KB-6165 delivers superior thermal reliability, withstanding repeated thermal cycles and high temperature exposure without degradation in performance or mechanical integrity. Therefore, this laminate is ideal for use in varying temperature ranges.
Low Z-CTE
With a low coefficient of thermal expansion (Z-CTE), the KB-6165 minimizes the risk of plated through hole (PTH) failures during thermal stress, ensuring long term reliability and durability of the PCB.
Anti-CAF Capability
The PCB material also has excellent anti-CAF performance. The laminate’s chemistry and controlled glass treatment provide excellent resistance to CAF, reducing the risk of dendritic growths that can cause shorts in high humidity or high bias conditions.
