The RO4350B 2.4mm 2oz 3u Gold 20-Layer High-Density IoT Gateway Board provides the structural and electrical architecture necessary for next-generation telecommunications and edge computing nodes. Designed specifically for high-frequency RF applications, this RO4350B 20-Layer IoT Gateway Board delivers exceptional signal velocity and low dielectric loss. Systems engineers and product developers utilise this multi-layer layout to aggregate dense sensor data streams while maintaining strict electromagnetic interference (EMI) suppression.

Key Features of the RO4350B 20-Layer IoT Gateway Board

• Material Stack-Up: Built with genuine Rogers RO4350B hydrocarbon ceramic laminates to maintain a stable dielectric constant ($D_k = 3.48 \pm 0.05$).

• Advanced Layer Count: A 20-layer high-density interconnect (HDI) configuration that supports complex routing matrices alongside dedicated power and ground planes.

• Copper & Plating: 2oz ($70\,\mu\text{m}$) copper weight across layers for enhanced current carrying capacity, finished with 3u ($\approx 0.076\,\mu\text{m}$) immersion gold (ENIG) for optimal solderability and oxidation resistance.

• Mechanical Dimensions: A precise 2.4mm overall board thickness providing mechanical rigidity for rack-mounted systems or rugged industrial enclosures.

• Manufacturing Compliance: Fully manufactured to meet IPC-A-600 Class 2 standards (Class 3 available upon request) and RoHS directives.

Applications

• Industrial IoT Gateways: Edge computing hardware handling massive sensor arrays and field telecommunications.

• Telecommunications Infrastructure: Base stations, small cell routers, and high-frequency microwave backhaul units.

• Smart Grid Systems: Automation controllers for regional power distribution and real-time monitoring networks.

• Aerospace Telemetry: Compact high-density data processing modules operating under variable thermal conditions.
