Engineered for High-Frequency Communications: The RO4350B Ceramic Hybrid PCB Solution

In the world of high-frequency communications where signal speed and integrity are paramount, 기준 PCB 재료 fall short. UGPCB introduces its high-performance 고주파 PCB solution based on Rogers RO4350B ceramic hybrid material. Designed for critical applications like communication instruments, 레이더 시스템, and satellite receivers, 이것 RF PCB delivers reliable and stable performance.

1. 제품개요 & 정의

This product is an 8-layer high-frequency PCB manufactured using a “Rogers RO4350B Laminates and FR4 Hybrid Lamination” 프로세스. This innovative Hybrid Construction PCB strategically combines high-performance ceramic-filled PTFE material (RO4350B) with cost-effective FR4. The RO4350B material is used in critical signal layers to ensure exceptional high-frequency performance, while FR4 is used in inner power and ground layers for optimal cost-efficiency. This Mixed Dielectric PCB 설계 represents an intelligent choice for balancing performance and budget.

2. 중요한 설계 고려 사항

1. 정밀한 임피던스 제어: 그만큼 RO4350B material offers a stable and low 유전 상수 (Dk=3.48). Combined with precision manufacturing processes, it enables highly accurate impedance control (typically ±5% or better), ensuring signal integrity for high-speed transmission.

2. Hybrid Stack-up Design: The design must clearly separate high-frequency signal layers (using RO4350B dielectric) from power/ground planes (which may use FR4). Rational stack-up planning is key to leveraging the benefits of hybrid material PCBs and controlling costs.

3. Low-Loss Design: The inherently low dissipation factor (Df) of RO4350B is foundational. Designers should also employ appropriate trace width, copper weight, and smooth copper foil surfaces (like reversed foil) to further minimize insertion loss.

4. 열 관리: Although the 열전도도 (0.69W/m.K) of RO4350B is superior to most standard FR4, high-power applications still require careful thermal management through proper layout, thermal vias, and potential additional heat sinking.

3. 작동 방식 & 주요 특징

작동 원리

고주파에서 (typically above 500MHz), skin effect is significant, and signal integrity is highly susceptible to the dielectric properties of the substrate. The RO4350B ceramic hybrid High Frequency Circuit Board minimizes signal energy loss (삽입 손실) and phase distortion during transmission through its stable dielectric constant and very low loss tangent, ensuring low-noise, 고 충실도 신호 전송.

주요 특징 & 성능
