1.6mm-Isola-FR408HR-TG190-4-Layer-PCB-with-Via-in-Pad-and-ENIG: Superior-Performance-and-AOI-Compatibility

Shipped: 4th-FEB-2025

1. FR408HR Introduction

Crafted with Isola's patented high-performance multifunctional resin system and reinforced with electrical-grade E-glass fabric, FR408HR delivers exceptional thermal and electrical properties. This advanced material system achieves a 30% improvement in Z-axis expansion and provides 25% greater electrical bandwidth (lower loss) compared to competing products, making it ideal for high-speed, high-frequency applications.

FR408HR also features superior moisture resistance during reflow, ensuring reliability in demanding environments. Its laser fluorescing and UV-blocking properties maximize compatibility with Automated Optical Inspection (AOI) systems, optical positioning systems, and photo-imageable solder mask imaging, streamlining manufacturing processes and enhancing quality control.

Designed to bridge the gap between thermal and electrical performance, FR408HR is the ultimate choice for cutting-edge PCB applications requiring precision, durability, and efficiency.

2. Key Features of FR408HR:
