High Frequency Board for Power Systems

A 4-layer high-frequency board built on Rogers RO4350B with FR-4 stiffener layers, 1.4mm thick, designed for high-frequency control and communication boards inside power-electronics systems. RO4350B's low Df keeps insertion loss flat across induction-heating and switching-converter frequencies, where signal transmission speed is inversely proportional to the square root of Dk — a low-Dk material moves data faster and keeps phase consistent. The hybrid stack combines RF performance with FR-4 mechanical and thermal robustness for hot, vibration-heavy environments around inverters and substations. Targets induction-heating control boards, smart-grid communication, high-frequency power converters, instrumentation in substations, and telecom site power equipment where reliability matters more than first-cost.
