2 Layer RO4350B PCB 30mil Immersion Silver Circuits

Introducing our newly shipped PCB featuring the RO4350B material, a cutting-edge solution for high-performance circuit designs. With its exceptional electrical properties and cost-effective manufacturing process, this PCB is an ideal choice for a wide range of applications.

RO4350B laminates are composed of proprietary woven glass reinforced hydrocarbon/ceramics, offering electrical performance similar to PTFE/woven glass materials and the manufacturability advantages of epoxy/glass. These laminates ensure tight control over the dielectric constant (Dk) while maintaining low loss, all while utilizing the same processing methods as standard epoxy/glass laminates. Compared to conventional microwave laminates, RO4350B laminates are available at a fraction of the cost and do not require special through-hole treatments or handling procedures like PTFE-based materials. Additionally, they are UL 94 V-0 rated, making them suitable for active devices and high-power RF designs.

One of the key benefits of RO4350B material is its thermal coefficient of expansion (CTE), which closely matches that of copper. This characteristic provides excellent dimensional stability, making it an excellent choice for mixed dielectric multi-layer board (MLB) constructions. The low Z-axis CTE of RO4350B laminates ensures reliable plated through-hole quality, even in severe thermal shock applications. Furthermore, the material has a high glass transition temperature (Tg) of over 280°C (536°F), ensuring its expansion characteristics remain stable throughout the entire circuit processing temperature range.

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

This PCB is optimized for performance and reliability, making it an excellent choice for various applications. The stackup consists of three layers: Copper Layer 1, Rogers RO4350B Core, and Copper Layer 2.Copper Layer 1 has a thickness of 35 μm, providing a solid and robust conductor for efficient signal transmission.At the core of our PCB lies the Rogers RO4350B material with a thickness of 0.762 mm (30 mil). Completing the stackup is Copper Layer 2, which has a thickness of 20 μm. This layer functions as the bottom conductor, offering additional routing options and providing a solid ground plane for improved signal integrity and electromagnetic compatibility.
