As part of our conversion to lead-free, I'm redesigning a pcb that had switch contact patterns screened on the board using carbon ink. On the new board, I plan on using the ENIG process and having the switch contacts be patterns of copper with the n

That uis correct if your wanting solderable gold it should be 10-17uinches, but for coantact suchas as switches and card edge 30 is used

I am a contract Mfgr. and we receive these designs quite frequently. ENIG is the finish and the designs do utilize pushbutton switches from membranes. I am not provvy to any reliability or performance data but we process alot of these designs. If

Thanks guys for your help. Sorry for the pic quality, the device is so small I had to zoom a lot with my phone. The switch is a tactile one, the plastic body is missing, and what you can see in the center is where the contact is made : when the swit
