Experience the cutting-edge technology of Kappa 438 PCB Material, featuring glass reinforced hydrocarbon ceramic composites that revolutionize electronic design. Engineered to meet the demands of modern technology, Kappa 438 offers exceptional performance and reliability for a wide range of applications.

With a dielectric constant (Dk) of 4.38 at 2.5 GHz and a dissipation factor of 0.005 at 10 GHz/23°C, Kappa 438 ensures superior electrical characteristics and efficient signal transmission. Its thermal coefficient of Dk of -21 ppm/°C allows for consistent performance in extreme temperature ranges from -50°C to 150°C, while its -40℃ to +85℃ operation ensures reliability even in challenging environments.

Features and Benefits:
a. Glass Reinforced Hydrocarbon Thermoset Platform: Kappa 438 provides the ease of PCB manufacturing and assembly, aligning with the industry-standard FR-4 process. This enables a seamless integration into existing production workflows, ensuring a smooth transition.

b. Dk Tailored to FR-4 Industry Standard Norms: With a Dk value of 4.38, Kappa 438 offers compatibility with FR-4 designs, making it an ideal choice when upgraded electrical performance is required. Experience enhanced performance without the need for significant design changes.

c. Tighter Dk and Thickness Tolerance than FR-4: Kappa 438 guarantees consistent circuit performance with tighter Dk and thickness tolerances compared to FR-4 materials. This ensures reliable and predictable electrical characteristics, allowing for precise control over signal integrity.

d. Low Z Axis CTE and High Tg: Kappa 438 provides improved design flexibility with its low Z Axis coefficient of thermal expansion (CTE) and high glass transition temperature (Tg). This enhances the reliability of plated-through holes (PTH) and ensures compatibility with automated assembly processes.

e. Flame Retardant Laminate: Safety is paramount, and Kappa 438 meets UL 94 V-0 standards, offering exceptional flame retardancy. This provides an additional layer of protection to your electronic designs.
