From prototyping through mass production, the board's stack-up structure and ground-plane continuity directly determine signal integrity and communication range. After switching to HDI PCB process, impedance control on RF traces finally stabilized, and the real trick was pulling the supplier in early to back-calculate trace width from actual material parameters instead of relying purely on simulation. This field report walks through real failures \u2014 dielectric constant batch drift, enclosure detuning, Wi-Fi coupling through the power plane \u2014 to show why the board shop matters more than any chip datasheet."}
