What Makes Rogers RO3003 Special?

Rogers RO3003 is not just any substrate material; it’s a game-changer in high-frequency PCB design. This laminate is a ceramic-filled PTFE composite with exceptional thermal, mechanical, and electrical properties. Here’s why it’s the ideal choice:

Stable Dielectric Constant (Dk):

RO3003 offers a consistent Dk of 3 ± 0.04 at 10 GHz and 23°C. This stability ensures predictable performance, even at high frequencies, making it perfect for radio frequency (RF) and microwave applications.

Low Loss Tangent:

With a dissipation factor of just 0.001 at 10 GHz, RO3003 minimizes signal loss, ensuring maximum efficiency in high-speed and high-frequency systems.

Wide Thermal Range:

With a decomposition temperature (Td) exceeding 500°C and low thermal expansion properties, it is well-suited for extreme temperature conditions.

Low Moisture Absorption:

At just 0.04%, RO3003 is highly resistant to environmental moisture, making it ideal for outdoor and high-humidity applications.

Mechanical Precision:

Its low in-plane coefficient of thermal expansion (CTE) closely matches copper, ensuring dimensional stability and reliability in surface-mounted assemblies.

PCB Stackup Overview

The stackup for this 2-layer rigid PCB is designed to maximize performance while maintaining a simple, robust structure:

Copper Layer 1: 35 μm thick for excellent signal integrity.

Rogers RO3003 Substrate: 5 mils (0.127 mm) for high-frequency stability.

Copper Layer 2: 35 μm thick for reliable grounding and power distribution.

This streamlined stackup ensures minimal signal loss, high durability, and optimal performance in high-frequency environments.

Why Choose ENIG Surface Finish?

The Electroless Nickel Immersion Gold (ENIG) finish on this PCB provides several advantages over other finishes:

Superior Solderability:

ENIG’s flat and smooth surface ensures excellent soldering results, reducing the risk of defects like bridging or tombstoning.

Long Shelf Life:

The gold layer prevents oxidation, ensuring the PCB maintains its quality even during long storage periods.

High Durability:

The nickel layer adds mechanical strength, protecting the copper traces from wear and tear during assembly and use.

Ideal for Fine Pitch Components:

ENIG is perfect for high-density designs with fine-pitch components, ensuring clean and precise connections.
