Why Rogers RO4350B?

RO4350B PCB is a proprietary woven glass-reinforced hydrocarbon/ceramic laminate. Its primary advantage lies in offering electrical performance nearing that of costly PTFE-based materials while maintaining the familiar, reliable processing techniques of standard FR-4. This eliminates the need for special via treatments or handling procedures, drastically simplifying fabrication and reducing cost.

Key material properties that benefit your design include:

1) Stable Electrical Performance: Tightly controlled Dk of 3.48±0.05 and a very low loss tangent (Df) of 0.0037 at 10 GHz ensure predictable, high-performance signal propagation.

2) Exceptional Thermal & Dimensional Stability: A high Tg >280°C and a CTE closely matched to copper result in outstanding dimensional stability during thermal cycles. This is crucial for reliable plated through-holes (PTH) and the integrity of multi-layer constructions, especially in applications involving thermal shock.

3) Proven Reliability: Features like low water absorption (0.06%) and a UL 94 V-0 flammability rating contribute to long-term reliability in harsh environments.

Full Product Specifications & Benefits:

• Artwork Format: Gerber RS-274-X
• Quality Standard: IPC-A-600 Class 2
• Availability: Worldwide support and shipping.

Key Benefits:

1) Optimized Cost-Performance Ratio: The hybrid design delivers RF performance where needed without the expense of a full Rogers board.

2) FR-4 Compatibility: Processes using standard epoxy/glass PCB methods, ensuring wider fabricator availability and faster turnaround.

3) Superior Reliability: Excellent PTH reliability and dimensional stability under thermal stress.

4) Design Flexibility: Ideal for complex multi-layer board (MLB) constructions requiring mixed dielectrics.

Typical Applications:

This Hybrid PCB Board is ideally suited for:

Cellular Base Station Antennas and Power Amplifiers

Automotive Radar Systems (e.g., ADAS) and Sensors

RF Identification (RFID) Tags and Readers

Low-Noise Block Downconverters (LNB) for Satellite Communication

High-Frequency Test Equipment and Prototyping
