Technical Configuration
4-Layer 0.85mmRogers RO4003C PCB supports 24 components with 55 total pads (43 thru-hole, 12 top SMT), interconnected through 23 vias across 5 nets. The stackup consists of Rogers 4003C cores (0.203mm and 0.406mm) with RO4450F bondply (0.101mm) for reliable multilayer bonding. Artwork files were supplied in Gerber RS-274-X format, and manufacturing complies with IPC-Class-2 quality standards.
Material Advantages
RO4003C PCB provides stable dielectric constant (3.38±0.05) and low dissipation factor (0.0027) at 10GHz, with thermal conductivity of 0.71 W/m/°K and Tg >280°C. The material processes like FR-4 but offers superior high-frequency performance. RO4450F bondply enables reliable multilayer construction with high thermal stability for sequential lamination cycles.
Typical Applications
• Cellular base station antennas and power amplifiers
• Automotive radar and sensor systems
• RF identification tags
• LNBs for direct broadcast satellites
