Introduction to Rogers RO4730G3 Material
Rogers RO4730G3 is an antenna-grade laminate with a UL 94 V-0 flammability rating, composed of hydrocarbon, ceramic, and woven glass. It acts as a reliable, cost-efficient alternative to traditional PTFE-based laminates, with resin systems that provide the key properties needed for optimal antenna performance. Fully compatible with standard FR-4 processing and high-temperature lead-free soldering, RO4730G3 eliminates the need for special plated through-hole (PTH) preparation that is required for conventional PTFE materials. This makes it an economical choice for antenna applications, allowing designers to effectively balance performance and cost.
Key Features of Rogers RO4730G3 Material
| Key Features | Specifications |
| Dielectric Constant (Dk) | 3.0 +/- 0.05 at 10GHz |
| Dissipation Factor | 0.0028 at 10GHz |
| Thermal Coefficient of Dk (TCDk) | 34 ppm/°C |
| Coefficient of Thermal Expansion (CTE) | X-axis: 15.9 ppm/°C; Y-axis: 14.4 ppm/°C; Z-axis: 35.2 ppm/°C (matched to copper) |
| Glass Transition Temperature (Tg) | Greater than 280 °C |
| Decomposition Temperature (Td) | 411 °C (measured via TGA) |
| Thermal Conductivity | 0.45 W/mk |
Benefits of Rogers RO4730G3 Material
-Low-loss dielectric paired with low-profile foil, which reduces Passive Intermodulation (PIM) and minimizes insertion loss.
-Unique filler and closed microsphere structure, offering low density and a 30% weight reduction compared to PTFE/Glass alternatives.
-Low Z-axis CTE (<30 ppm/°C) and high Tg (>280°C), providing greater design flexibility and compatibility with automated assembly processes.
-Low TCDk (<40 ppm/°C), ensuring consistent circuit performance across varying temperature conditions.
-Specialized thermoset resin system and filler, delivering low TCDk, a 3.0 Dk value, ease of fabrication, and plated through-hole (PTH) process capability.
-Environmentally sustainable, with compatibility for lead-free processing and compliance with RoHS standards.
