What is The KB-6168LE PCB Material?
KB-6168LE is a high Tg laminate designed for applications requiring elevated thermal resistance and electrical stability. With a lead free DSC Tg of 190°C, the laminate offers excellent thermal endurance under harsh operating conditions. This high Tg value translates into better dimensional stability, reduced risk of delamination, and extended service life for multilayer boards. The material exhibits a low dielectric constant (Dk 4.6 @1GHz) and low dissipation factor (Df 0.016 @1GHz), ensuring minimal signal loss and stable electrical performance even under high speed operating conditions.
What makes KB-6168LE truly stand out is its extremely low Z-axis Coefficient of Thermal Expansion (Z-CTE). This characteristic significantly reduces the mechanical stress on vias during thermal cycling, improving reliability for complex and densely packed circuit designs. The material also boasts strong Anti-CAF capability, which enhances resistance against conductive anodic filament formation, ensuring long term insulation and safety.
It is particularly well suited for high end automotive electronics, including engine control units and electric vehicle (EV) platforms, where high current and high temperature conditions prevail. Its ability to operate reliably under elevated temperatures makes it a preferred choice for power modules and battery management systems in EVs. Beyond automotive use, KB-6168LE also finds applications in industrial high power supplies, where it ensures operational stability, reduced maintenance needs, and improved thermal management. The material’s robust performance under electrical and thermal stress positions it as a go to option for mission critical electronics.

Features of The KB-6168LE PCB Material
High Glass Transition Temperature (Tg 190°C)
The cornerstone of KB-6168LE is its high Glass Transition Temperature (Tg) of 190°C, measured by DSC test condition. This significantly exceeds standard materials, meaning KB-6168LE maintains its structural integrity and mechanical properties at much higher operating temperatures. This is crucial for lead free soldering processes (which involve higher temperatures) and applications generating significant heat.
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. The laminate 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.
Excellent Thermal Reliability
With superior thermal endurance, the KB-6168LE performs reliably under thermal cycling, high temperature operation, and harsh environmental conditions, contributing to longer product life and reduced failure rates.
Extremely Low Z-CTE
The KB-6168LE features an extremely low coefficient of thermal expansion in the Z-axis, which significantly minimizes the risk of plated through hole (PTH) failures during thermal stress. This ensures enhanced reliability and durability in multi-layer PCBs.
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.
