Substrate Selection by Field Strength
Substrate Df directly affects coil Q-factor and MRI SNR. At 64MHz (1.5T), RO4350B (Df 0.0037) produces acceptable substrate loss. At 298MHz (7T), RO3003 (Df 0.0010) is required — RO4350B substrate loss at 298MHz degrades coil Q measurably. For a full analysis of material selection by field strength, see MRI RF coil PCB material selection.

Why ENIG for MRI RF Coil PCB
ENIG (Electroless Nickel Immersion Gold) is the standard surface finish for MRI RF coil PCB for three reasons: flat surface maintains trace dimensional accuracy for resonant frequency precision; no lead content for patient-contact biocompatibility; and uniform gold surface provides consistent solderability for capacitor placement around the coil loop. HASL produces surface roughness that affects conductor Q at RF frequencies and should not be specified for coil PCBs. ENEPIG is available where wire bonding or additional biocompatibility requirements apply.
