4-Layer Rogers Ceramic Hybrid High-Frequency PCB Layer Stack-up

1. Product Overview & Definition

ال RO4350B Ceramic Hybrid High Frequency PCB is a high-performance لوحة الدوائر المطبوعة engineered for radio frequency (RF) and microwave applications. It innovatively combines Rogers RO4350B ceramic-filled hydrocarbon laminate with standard FR4 epoxy glass material through multi-layer PCB lamination technology. هذا “hybrid” approach allows critical RF circuits (على سبيل المثال, antennas, المرشحات, amplifiers) to be routed on the low-loss RO4350B areas, while cost-sensitive digital control and power management circuits reside on the FR4 areas, achieving an optimal balance between performance and cost.

2. Core Material & بناء

مواد: This product features a روجرز RO4350B + FR4 mixed laminate بناء. RO4350B is a ceramic-filled thermoset polymer material known for its stable dielectric constant (DK) and low dissipation factor (ص). FR4 is a standard epoxy glass weave laminate, valued for its economy and versatility.
بناء: This model is a standard 4-طبقة ثنائي الفينيل متعدد الكلور. عادة, the outer layers (L1 & L4), which host RF circuitry, use RO4350B dielectric, bonded to the inner FR4 core using prepreg. This structure ensures signal integrity in RF paths while reducing overall material cost.
المواصفات الرئيسية & امتثال:
- ثابت العزل الكهربائي (DK): 3.48 @ 10 GHz. This stable value minimizes phase shift and impedance variance, crucial for controlled impedance PCB design.
- الموصلية الحرارية: 0.69 W/m·K. Superior to standard FR4, aiding heat dissipation from active RF components and improving long-term reliability.
- Flammability Rating: أول 94 V-0. Meets the highest standard for flame retardancy.
- الانتهاء من السطح: الغمر الذهب (يوافق). Provides a flat, solderable surface, excellent oxidation resistance, and long shelf life, ideal for high-frequency SMT assembly و PCBA processes.
- سمك الانتهاء: 1.0 مم
- Copper Weight: 1 أوقية (35 ميكرومتر)

3. اعتبارات التصميم الحرجة & Operational Principle

السيطرة على المعاوقة: RF transmission lines (على سبيل المثال, microstrip, stripline) require precise impedance control (typically 50Ω or 75Ω). Designers must calculate trace width using the stable Dk of RO4350B (3.48) and dielectric thickness (0.762مم) to ensure minimal signal reflection.
Hybrid Zone Transition: Signal transitions between RO4350B and FR4 areas cause impedance discontinuities due to Dk mismatch. Optimal تخطيط ثنائي الفينيل متعدد الكلور requires mitigation techniques like tapered traces, matching networks, or optimized via transitions.
الإدارة الحرارية: Despite its improved thermal conductivity (0.69 W/m·K), high-power RF designs may still require thermal vias, heatsinks, or metal-core substrates for effective PCB thermal management.
Operational Principle: هذا لوحة الدائرة acts as the physical substrate and transmission medium for RF signals. Its core function is to utilize the low-loss, low-dispersion properties of RO4350B to transmit electromagnetic signals with high efficiency and minimal distortion across target frequency bands (from hundreds of MHz to tens of GHz), while integrating control logic via the hybrid structure for complete system functionality.

4. الميزات الرئيسية & Advantages
