TU-872 SLK Sp FR-4 Radio Frequency PCB Low Dk and Df High Thermal Reliability Printed Circuit Board

Printed Circuit Boards are custom-made products; the images and specifications provided are for reference only.

Brief Introduction

TU-872 SLK Sp is a high-performance PCB laminate built on a modified epoxy FR-4 resin system. TU-872 PCB features reinforcement with advanced woven glass fibers and is engineered to deliver an extremely low dielectric constant and low dissipation factor, making it ideal for high-speed, low-loss, and high-frequency circuit board applications.

TU-872 material is fully compatible with environmentally friendly lead-free manufacturing processes while maintaining compatibility with standard FR-4 production workflows. TU-872 SLK Sp laminates offer a range of enhanced properties, including excellent coefficient of thermal expansion (CTE), superior resistance to chemicals and moisture, robust thermal stability, and strong resistance to conductive anodic filament (CAF) formation. Additionally, the inclusion of an allyl network-forming compound significantly improves the material's toughness.
