I've been testing various conductive inks and have printed them on a paper substrate. What is the best way for me to affix the NFC ICs to them? I've googled but can't find the answer I need. Thanks in advance.
Hello Ben Wung,
I have not seen tag designs with conductive ink printed antennas, so not much expertise on the topic. Ideally the NTAG21x IC should be next to the antenna with a direct connection, maybe pasting the IC to the same material and routing the IC pins to the antenna using the conductive ink. Another possibility might be to use a conductive adhesive to paste a SMA connector on the antenna side and another on the NTAG21x board side and use a short cable, although this kind of union could have a negative impact on the performance or sensitivity.
