Hey, first thing: label every lead and every connector, even the tiny ones, so you can trace every path later. Then map the impedance of each segment with your multimeter and check it against the spec sheet—don’t just trust the drawing. Make sure the return path for the coil is a single, low‑impedance trace back to the shield, not a tangle of wires. Keep the grounding bus isolated from any RF noise and use a dedicated ground plane under the coils. Double‑check that the ground plane is continuous; a gap can turn a clean coil into a noisy source. Finally, wrap the whole assembly in a Faraday cage if you’re in a lab with a lot of wireless gear—my multimeter hates interference. That should keep the performance specs in line and the short‑circuit risk minimal.
