Kappa 438 High Frequency PCB

 

Shot 1: Introduction

Rogers Kappa 438 PCB was developed to address the growing performance demands of the wireless market, which traditional FR-4 materials could not meet. As wireless data usage has surged, the need for higher network capacity and reliability has become crucial. Kappa 438 offers superior dielectric properties, lower loss, and tighter tolerances, making it ideal for advanced RF applications, including small cells and carrier-grade Wi-Fi.

 

Rogers Kappa 438 laminates were designed using a glass reinforced hydrocarbon ceramic system that offers superior high frequency performance and low cost circuit fabrication resulting in a low loss material which can be fabricated using standard epoxy/glass (FR-4) processes.

 

 

 

Shot 2: Features

Kappa 438 laminates offer dielectric constants (Dk) of 4.38 at 2.5GHz, which is tailored to FR-4 industry standard norms, facilitating smooth integration into existing designs that demand improved electrical performance.

 

Rogers Kappa 438 has tighter Dk and thickness tolerances compared to traditional FR-4, enabling more precise circuit design and improved signal integrity.

 

Additionally, Kappa 438 boasts low X Y and Z-axis coefficient of thermal expansion (CTE) of 13, 16, and 42 ppm/°C respectively, allowing for greater dimensional stability and plated through hole reliability under varying thermal conditions.

 

The high glass transition temperature (Tg) of over 280°C (TMA) ensures that Kappa 438 can withstand demanding thermal environments, making it suitable for a wide range of applications.

 

Furthermore, it meets UL 94-V0 flame retardant requirements, providing enhanced safety and reliability in critical electronic systems.
