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 #TinyTapeout QC stickers to celebrate solving the mystery of the poor antenna performance! 🎉

We've got the trinocular microscope out today while we debug the latest production batch of Vicino NFC boards

Although @huffeec did sterling work to solder the 0.6mm square varicaps on the test boards, we got robots to place the parts on the first production batch.

They've just arrived from the production house and are looking lovely! 😍

Anyone want an NFC/RFID board? We'll have some on our @tindie store soon.

Today I am mostly antenna tuning.

Here's my macgyvered RF probe and test setup
