2. Application Scenario Analysis for Each Model
2.1 RO4003 – Ideal Choice for Multilayer Boards
RO4003 offers stable Dk values and CTE that matches copper foil well, making it very suitable for multilayer hybrid lamination structures. In high-density interconnector PCB projects with 6 or more layers, STG Electronic often recommends customers use RO4003 as the core layer material.

Typical Applications: Base station power amplifier modules, microwave backplanes
2.2 RO4350B – The Most Versatile High Density Interconnector PCB Material
RO4350B is Rogers' best-selling high-density interconnector PCB material, combining excellent RF performance with processing convenience. It features Dk=3.48, high mechanical strength, is not brittle, and can be processed using standard FR4 processes.

STG Electronic Suggestion: If you are using high-density interconnector PCBs for the first time, RO4350B is the safest choice.
Typical Applications: Antenna boards, automotive radar, RFID (Radio Frequency Identification)
2.3 RO5880 – Ultimate High-Frequency Performance
RO5880 has a Df as low as 0.0009, making it a leader among PTFE-based materials with extremely low signal loss. However, PTFE material is relatively soft and difficult to process, requiring a professional high-density interconnector PCB manufacturer to ensure good yield.
