Isola Astra MT77 PCB 2-Layer 10mil 0.254mm Immersion Gold Low-loss Dielectric Board

Isola Astra MT77 PCB 2-Layer 10mil 0.254mm Immersion Gold Low-loss Dielectric Board

Designed for next-generation millimeter wave and RF/microwave applications, the MT77 2-Layer 10mil Immersion Gold PCB stands out as a cost-effective, high-performance solution—leveraging the breakthrough Astra MT77 laminate to deliver exceptional electrical stability and processing flexibility. Ideal for automotive radar systems and commercial RF designs, this Low-loss Dielectric PCB combines tight manufacturing tolerances, reliable construction, and industry-compliant standards to meet the demands of high-frequency applications where signal integrity and durability are non-negotiable. Below is a detailed breakdown of its specifications, design advantages, and application capabilities.

Core Material: Astra MT77 Laminate

At the heart of this PCB is Astra MT77, alow-loss dielectricPCBmaterial engineered for millimeter wave frequencies and beyond. Its ultra-low dissipation factor (Df = 0.0017 at 2/10 GHz) and stable dielectric constant (Dk = 3.0 at 2/10 GHz/23°C) outperform traditional alternatives like PTFE, while offering significant cost savings. The material maintains electrical stability across a broad temperature range (-40°C to +140°C) and up to W-band frequencies, making it perfect for harsh automotive environments. With a Tg of 200°C, UL 94-V0 flammability rating, and lead-free compatibility, Isola Astra MT77 ensures long-term reliability and compliance with global manufacturing standards.

Key Features & Performance Advantages

Beyond its core material, the MT77 2-Layer PCB boasts standout features that elevate its performance:

1)Exceptional peel strength (5.7 lb/inch for 1oz copper) ensures robust component adhesion;

2)Minimal moisture absorption (0.1%) prevents performance degradation in humid environments;

3)Controlled thermal expansion (CTE: X/Y = 12 ppm/°C, Z = 250-350 ppm/°C) maintains dimensional stability under temperature fluctuations;

For manufacturers, its processing advantages are a game-changer: FR-4 process compatibility reduces production complexity, while short lamination cycles and reduced drill wear lower manufacturing costs. The material eliminates the need for plasma desmear, offers good flow/fill during assembly, and supports advanced designs like HDI, VIPPO, and multiple lamination cycles—providing flexibility for custom configurations.

Typical Applications

This Astra MT77 PCB is purpose-built for automotive radar and long-antenna systems, including:

• Adaptive cruise control
• Pre-crash detection
• Blind spot monitoring
• Lane departure warning
• Stop-and-go systems

Its low-loss properties and temperature stability make it indispensable for these safety-critical applications, where precise signal transmission directly impacts performance. Additionally, it suits commercial RF/microwave designs requiring reliable high-frequency operation.

Availability & Compliance

Supplied with Gerber RS-274-X artwork (the industry standard for PCB manufacturing), the MT77 2-Layer Immersion Gold PCB is available worldwide. It meets lead-free process requirements and UL 94-V0 safety standards, ensuring compatibility with global supply chains and regulatory frameworks.

Whether you’re developing next-gen automotive radar or high-performance RF systems, this PCB delivers the perfect balance of electrical performance, manufacturing flexibility, and cost-effectiveness—backed by the proven reliability of Astra MT77material.
