Rogers RO3203 Material Introduction

Rogers RO3203 is a premium high-frequency circuit material designed as an extension of the RO3000 Series, with a key focus on improved mechanical stability without compromising electrical performance. As a ceramic-filled laminate reinforced with woven fiberglass, it balances three critical attributes: exceptional electrical performance (suitable for frequencies beyond 40 GHz), robust mechanical stability, and competitive pricing—making it ideal for volume manufacturing of high-frequency devices.

Its core electrical properties—dielectric constant (Dk) of 3.02 and dissipation factor (DF) of 0.0016—enable reliable signal propagation at ultra-high frequencies, while its woven glass reinforcement ensures durability during handling and assembly. Unlike some high-frequency materials, RO3203 is also lead-free process compatible, aligning with global environmental standards.

RO3203 Key Features

The material’s features are tailored to meet the strict demands of ultra-high-frequency applications, combining electrical excellence with mechanical resilience:

Benefits

RO3203’s properties translate to tangible advantages for the PCB, addressing key challenges in ultra-high-frequency design and volume manufacturing:

Ultra-High-Frequency Performance: Low DF (0.0016) and stable Dk (3.02 ± 0.04) enable reliable operation beyond 40 GHz.

Mechanical Stability: Woven glass reinforcement improves rigidity, making the PCB easier to handle during assembly and resistant to warpage.

Thermal Compatibility: Low in-plane CTE (13 ppm/°C for X/Y axes) matched to copper prevents solder joint failure during thermal cycling, supporting reliable surface-mounted assemblies.

Cost-Effectiveness: Economically priced for volume manufacturing, reducing total production costs without sacrificing high-frequency performance.

Surface Smoothness: Enables finer line etching tolerances for precise high-frequency circuit routing.

Safety & Compliance: UL 94 V-0 flammability rating and lead-free compatibility meet global safety and environmental standards.

Typical Applications

This PCB is designed for use in critical electronic systems, including:

-Automotive: Collision avoidance systems, GPS antennas

-Wireless Communications: Base station infrastructure, LMDS (Local -Multipoint Distribution Service), wireless broadband, microstrip patch antennas

-Satellite & Telecom: Direct broadcast satellites (DBS), wireless telecommunications systems, datalink on cable systems

-Industrial & Consumer: Remote meter readers, power backplanes

Availability: Worldwide

This PCB is globally accessible for production and delivery, addressing the logistical needs of multi-region high-frequency projects.
