Data Sheet

1. Overview of Rogers RO4350B Material

Rogers RO4350B is a high-performance hydrocarbon-based composite laminate, featuring a stable dielectric constant (DK) of 3.48. It is specially designed for high-frequency RF/microwave PCB applications, integrating excellent electrical performance and processability to meet the strict requirements of modern electronic product manufacturing.

2. Core Advantages of Rogers RO4350B

Rogers RO4350B boasts comprehensive performance advantages, making it a preferred material for RF/microwave PCBs. Its key advantages are as follows:

Low dielectric loss (DF): Effectively reduces signal attenuation during high-frequency transmission, ensuring the integrity and stability of RF signals.
Low dielectric constant (DK) fluctuation with temperature: Maintains stable DK performance under different working temperature conditions, adapting to diverse environmental operating requirements of electronic products.
Low z-axis thermal expansion coefficient (CTE): Reduces the risk of plated through-hole (PTH) failure in multi-layer PCBs caused by thermal expansion mismatch, improving the structural reliability of the board.
Low in-plane expansion coefficient: Minimizes internal stress of the PCB, avoiding board warpage and ensuring dimensional stability during processing and use.
Low dielectric constant (DK) tolerance: Ensures consistent performance of batch products, facilitating quality control in mass production and reducing product performance deviation.
Stable electrical characteristics at different frequencies: Adapts to a wide range of high-frequency bands, with strong applicability in various RF/microwave scenarios.
Easy for mass production and compatible with FR4 multi-layer mixing: It can be seamlessly mixed with FR4 materials for multi-layer PCB manufacturing, achieving a balance between performance and cost, and featuring high cost-effectiveness.

3. Dielectric Constant vs. Temperature of Rogers RO4000 Series Materials

As a key member of the Rogers RO4000 series, RO4350B inherits the excellent temperature stability of the series. The dielectric constant of RO4000 series materials shows minimal fluctuation with temperature changes, which is one of the core reasons why the series is widely used in high-frequency applications requiring stable performance under extreme temperature conditions.

4. RF/Microwave PCB Application Introduction

Radio frequency (RF) PCBs have become an increasingly important technology in the PCB industry, with applications expanding rapidly with the development of new electronic technologies. They are classified based on operating frequency:

RF PCBs: Operating at frequencies above 100 MHz, suitable for general high-frequency electronic devices.
Microwave PCBs: Operating at frequencies above 2 GHz, mainly used in high-frequency communication and detection equipment.

RF PCBs are widely applied in various fields, including remote controls (wireless controls), security systems, smartphones, sensors, and other electronic products. The continuous development of new technologies has further expanded the application scope of RF PCBs, which puts forward higher requirements for manufacturing quality standards and material selection.

Understanding the properties of various RF materials is crucial for PCB manufacturing. Choosing the right RF material is perhaps the most critical decision in the production process of RF PCBs, as it directly determines the performance, reliability, and cost-effectiveness of the final product.
