Introducing one newly shipped PCB built on RO4350B laminate. It's a high-performance laminate that combines the electrical properties of PTFE/woven glass with the manufacturability of epoxy/glass. With its proprietary woven glass reinforced hydrocarbon/ceramic materials, the RO4350B offers exceptional electrical performance while being cost-effective to produce.
The RO4350B laminates provide precise control over the dielectric constant (Dk) and maintain low loss, using the same processing methods as standard epoxy/glass laminates. Unlike conventional microwave laminates, RO4350B laminates do not require special through-hole treatments or handling procedures, simplifying the manufacturing process. Additionally, these materials are UL 94 V-0 rated, ensuring their suitability for active devices and high-power RF designs.
With a dielectric constant of DK 3.48 +/-0.05 at 10GHz/23°C and a dissipation factor of 0.0037 at 10GHz/23°C, the RO4350B PCB ensures accurate and reliable signal transmission. It exhibits a thermal conductivity of 0.69 W/m/°K, contributing to efficient heat dissipation. The PCB demonstrates a low coefficient of thermal expansion (CTE) with 10 ppm/°C for the X axis, 12 ppm/°C for the Y axis, and 32 ppm/°C for the Z axis. It also possesses a high Tg value of >280 °C, ensuring stability under elevated temperatures. With a low water absorption rate of 0.06%, the PCB maintains excellent dimensional stability.
The RO4350B PCB offers numerous benefits for your applications. It is ideal for multi-layer board (MLB) constructions and can be processed like FR-4 at a lower fabrication cost, providing a cost-effective solution for high-performance designs. Additionally, it offers excellent dimensional stability, ensuring reliable performance in demanding environments. The RO4350B PCB is competitively priced, offering exceptional value for its performance capabilities.
