Working out that my multimeter isn't good enough to measure 10pF and resigning myself to swapping out a dozen various 0603 capacitors to work out which ones have been specced wrong.

I guess that's a simpler task than the swapping out a couple of hundred 0603 capacitors that I'm expecting will be the next step once I track down the bug.

Though there's a chance that'll be the fab house's problem rather than mine

The detritus from today's rework. Oh, plus a dead NFC board because it's really easy to lift a 1.34mm long trace when desoldering the 0603 cap at one end of it 😀

However, I found that two of the cap values were wrong. Four capacitors in total. I'm guessing the reels got swapped over when loaded in the pick-and-place machine?

Anyway, broke out the QC stickers to celebrate solving the mystery of the poor antenna performance! 🎉
