The RO4350B 0.25mm 2-layer PCB is an ultra-thin, high-frequency circuit board that perfectly balances RF performance with manufacturing cost-efficiency. Utilizing Rogers' proprietary woven glass reinforced hydrocarbon/ceramic material, this PCB delivers exceptional electrical characteristics (Dk 3.48±0.05) while maintaining processability similar to standard FR-4. The 0.25mm thin profile, combined with a copper-matched CTE, ensures high reliability for plated through-holes under demanding thermal conditions. Rated UL 94 V-0 with low water absorption (0.06%), it is the ideal choice for compact, high-power RF designs.
