The RO4350B 1.2mm 1oz ENIG 4-layer wireless charging transmitter PCB is a high-frequency circuit board designed specifically for efficient near-field power transfer systems. Engineered to meet the strict demands of RF and power electronics developers, this multiplayer printed circuit board utilizes premium Rogers hydrocarbon ceramic laminates to manage tight impedance controls and minimise insertion loss.
Key Features of the RO4350B 4-Layer Wireless Charging PCB
-
Premium Base Material: Rogers RO4350B woven glass-reinforced hydrocarbon/ceramic laminate for superior high-frequency performance.
-
Optimised Stackup: 4-layer configuration with a 1.2mm overall board thickness, balancing mechanical rigidity with compact housing requirements.
-
Copper Weight: 1oz ($35\,\mu\text{m}$) outer and inner layers to handle transmitter coil currents without excessive temperature rise.
-
Surface Finish: RoHS-compliant Electroless Nickel Immersion Gold (ENIG) offering flat component landing pads for precise surface-mount technology (SMT) assembly and long shelf life.
-
Thermal and Electrical Stability: Low dissipation factor ($\tan\delta = 0.0037$ @ 10 GHz) and a stable dielectric constant ($D_k = 3.48 \pm 0.05$) across a wide temperature range.
Applications
This 4-layer transmitter board is built for integration into high-reliability wireless power charging ecosystems across multiple sectors:
-
Industrial automation and contactless sensor charging stations.
