Why Choose a 4-Layer 5mil RT6202+FR-4 Hybrid PCB for High-Frequency RF Designs? Introduction When designing RF and microwave circuits above 3 GHz, engineers face a persistent dilemma: standard FR-4 substrates introduce unacceptable signal loss and dielectric instability, while fully Rogers-based multilayer boards carry prohibitive material costs for digital and power sections. A 4-layer 5mil RT620...

How to Select 1080 Prepreg for Rogers RO3010 and FR-4 Hybrid Lamination? Introduction Hybrid multilayer PCBs that pair ceramic-filled PTFE high-frequency laminates such as Rogers RO3010 with conventional FR-4 prepreg have become a standard construction for cost-sensitive RF designs. Place the premium high-Dk material only where RF signals travel, and use economical FR-4 bonding sheets elsewhere. Y...
