Key Features & Benefits
1. Optimized for Millimeter-Wave (mmWave)
The RO4830 laminate is specifically designed for 77 GHz applications. Unlike standard FR-4, it features a flat woven glass-free thermoset dielectric which ensures a stable $D_k$ across the entire panel. This reduces phase variation and insertion loss, making it the gold standard for high-frequency transmitter antennas and feed networks.
2. Superior Power Handling (2oz Copper)
High-power transmitters generate significant heat. By utilizing 2oz (70µm) copper on all layers, this board significantly improves current-carrying capacity and thermal dissipation. The 1.5mm thickness provides the structural rigidity needed to prevent warping under high thermal loads.
3. Hard Gold Finish for Wear Resistance
Unlike ENIG, our Hard Gold finish is alloyed with cobalt or nickel to provide extreme hardness. This makes it ideal for edge connectors, sliding contacts, or mounting points that require frequent mating cycles or high mechanical stress without degrading electrical conductivity.
4. Advanced 10-Layer Stackup
With 10 layers, this board allows for a sophisticated power distribution network (PDN).
