They seem similar: both are high-end PCBs that require impedance control and signal quality assurance. They are often used together: one board can carry both RF and high-speed digital signals. Industry habit: People commonly say "high-frequency and high-speed boards", so they gradually become regarded as a single concept. But in professional design and manufacturing, they follow completely differe

In PCB production communication and specification sheets, we often hear "1oz copper thickness" and default that it corresponds to approximately 35 microns (μm). This seemingly regular value is not arbitrarily set, but a result of precise physical definitions, unit conversions, and industry practice conventions. The logic behind it is clearly explained from three aspects: definition, conversion, an
