Double Sided RF-35 PCB 30 Mil Immersion Gold Finished Pcb Board

As technology advances, the demand for high-performance printed circuit boards (PCBs) continues to grow, particularly in the realms of microwave and radio frequency (RF) applications. The newly shipped RF-35 PCB from Taconic represents a significant leap forward in this sector, offering a unique combination of affordability, performance, and reliability. In this article, we will explore the features, benefits, technical specifications, and applications of the RF-35 PCB, providing a comprehensive understanding of why it is the ideal choice for engineers and manufacturers alike.

Introduction to the RF-35 PCB

The RF-35 PCB is an organic-ceramic laminate that belongs to Taconic's ORCER family of products. It is constructed using woven glass reinforcement, a technique that enhances the mechanical strength and thermal stability of the material. Taconic's expertise in ceramic fill technology and coated PTFE fiberglass culminates in the RF-35, making it a robust solution for various RF applications.

Why Choose RF-35?

The RF-35 PCB is particularly well-suited for low-cost, high-volume commercial applications. Its exceptional properties make it an attractive option for manufacturers seeking reliable performance without the associated high costs of traditional materials. Key advantages include excellent peel strength, ultra-low moisture absorption, and low dissipation factor, all of which contribute to its superior performance in demanding environments.

Key Features and Benefits

Dielectric Properties

At the heart of the RF-35's performance are its impressive dielectric properties. With a dielectric constant of 3.5 at 1.9GHz and a dissipation factor of just 0.0018, the RF-35 minimizes signal loss and ensures consistent performance across a wide range of frequencies. These properties are crucial for applications where signal integrity is paramount.

Mechanical and Thermal Stability

The RF-35 PCB exhibits a dielectric breakdown of 41 kV, showcasing its ability to withstand high voltage applications. Additionally, its low coefficients of thermal expansion (CTE)—19 ppm/°C in the X direction, 24 ppm/°C in the Y direction, and 64 ppm/°C in the Z direction—ensure dimensional stability during thermal cycling. This stability is essential for maintaining the integrity of circuits in environments that experience temperature fluctuations.

Flammability and Safety

With a UL-94 V0 flammability rating, the RF-35 PCB meets stringent safety standards, making it suitable for a wide range of applications. This rating is particularly important in industries where safety is a critical concern, such as telecommunications and automotive.

Low Cost and High Performance

The RF-35 PCB is designed for high-volume production, allowing manufacturers to keep costs low while maintaining high performance. Its excellent peel strength for 1/2 ounce and 1 ounce copper layers facilitates easy rework, a significant advantage in production environments where modifications may be necessary.

Moisture Resistance

The ultra-low moisture absorption rate of the RF-35 PCB enhances its reliability in humid environments. This characteristic is vital for applications in outdoor or high-humidity settings, where moisture can compromise performance.
