RO4350B High Frequency PCB 2-Layer 20mil 0.508mm Substrates

Shipped: 25th-JAN-2024

1. RO4350B Introduction
Rogers RO4350B materials are proprietary woven glass reinforced hydrocarbon/ceramics with electrical performance close to PTFE/woven glass and the manufacturability of epoxy/ glass.

RO4350B laminates provide tight control on dielectric constant (Dk) and maintain low loss while utilizing the same processing method as standard epoxy/glass. Available at a fraction of the cost of conventional microwave laminates, RO4350B laminates do not require the special through-hole treatments or handling procedures as PTFE based materials. These materials are UL 94 V-0 rated for active devices and high power RF designs.

2. Features
- Dielectric Constant of DK 3.48 +/-0.05 at 10GHz/23°C
- Dissipation Factor of 0.0037 at 10GHz/23°C
- Thermal Conductivity 0.69 W/m/°K
- X axis CTE of 10 ppm/°C, Y CTE of 12 ppm/°C, Z CTE of 32 ppm/°C
- High Tg value of >280 °C
- Low water absorption of 0.06%

3. Benefits:
- Ideal for multi-layer board (MLB) constructions
- Processes like FR-4 at lower fabrication cost
- Excellent dimensional stability
- Competitively priced
