6-Layer Hybrid RF/FR-4 PCB with RO4003C Core - 1.1mm Thick, 4/6 Mils Trace/Space, ENIG Finish
(All PCBs are custom-manufactured. Reference images and parameters may vary based on your design requirements.)
1. Product Overview
This 6-layer hybrid PCB combines Rogers RO4003C high-frequency material with Shengyi S1000-2 FR-4 to deliver optimal performance for RF and digital applications. Designed for cellular base stations, automotive radar, and satellite communications, this board features 1oz copper layers and matte green solder mask for professional applications.

Key Benefits:
1. Cost-Effective RF Solution: Combines RO4003C performance with FR-4 affordability
2. Thermal Reliability: High Tg FR-4 (170°C) with excellent CAF resistance
3. Precision Manufacturing: 4/6 mils trace/space with standard 0.35mm vias
4. Robust Construction: 1.1mm thickness with matte green protection
5. Global Availability: Prototype to production support worldwide
