PCB noob here: is there a good resource on how to make capacitive touch buttons on PCBs (dos and don'ts)?

@bleeptrack this might be obvious, but make sure to use lead-free surface finish! I once tried this Arduino code playground.arduino.cc/Code/Cap and it worked well.

capacitive touch 

@sebastian true capacitive sensing does not use exposed metal contacts

@bleeptrack it depends on the capacitive touch controller you use; look into its datasheet for recommendation

from an UX perspective, some kind of feedback is absolutely necessary

I personally find capacitive touch most of the time rather annoying and inferior to tactile switches, but there surely are applications where it is the way to go
