Introduction

Rogers RO4830 high frequency laminates are thermoset materials that offer a reliable and cost-effective alternative to conventional PTFE-based laminates. They are particularly well-suited for millimeter wave applications where cost considerations are important, such as automotive radar sensors operating in the 76-81 GHz range. RO4830 laminates can be manufactured using standard FR-4 processes and are designed to be used as the cap layer in FR-4 multi-layer board designs commonly employed in 76-81 GHz automotive radar sensor PCB applications.

Compared to PTFE-woven glass laminates, RO4830 laminates exhibit a slightly higher dielectric constant of 3.2 at 77 GHz. The use of low profile reverse treated copper foil cladding contributes to excellent insertion loss performance of RO4830 laminates at 77 GHz, achieving 2.2 dB per inch. The laminates also benefit from a flat woven e-glass and a filler with smaller and more uniform particle size, resulting in good laser drilling capabilities. Additionally, RO4830 laminates contain an advanced anti-oxidant package that provides significant resistance to oxidation, surpassing other hydrocarbon-based laminate materials. These laminates have a UL 94 V-0 flame retardant rating and are compatible with lead-free solder processes.

Key Features:

1. Dielectric constant of 3.24

2. Excellent insertion loss of 2.2 dB/in at 77 GHz

3. UL 94 V-0 flame retardant rating

4. Optimized filler, resin, and glass composite system

5. Reverse treated smooth low profile copper foil

Benefits:

• Remarkable resistance to oxidation
• Consistent within-sheet dielectric constant for reliable laser drilling performance
• Lower overall cost compared to PTFE laminate options, contributing to reduced PCB manufacturing expenses
• Ideal for automotive radar sensor PCB applications
