Just curious if anyone has any recommendations for PCB processes or finish types for the most durable pads.

The application is a docking-type cradle where one side of the PCB will be exposed to air, fingers, etc with only pads and mask (no components or solder).

I think the standard soldermask and ENIG copper pads are fine, but if there's anything I can request that's even better for durability, please let me know so I can read up on it :smile:
 

put the board in a box and add an environment appropriate bulkhead connector
use an appropriate mating connector on the other part

Okay let's pretend I'm doing that. But let's also pretend I want the most durable PCB pads that money can buy for my PCB that's safely inside a sealed box. What processes are more durable than others?

(In reality, the "exposed" PCB will only be occasionally exposed. 99% of the time it will be mated inside a sealed piston or have a blanking plug that's also sealed covering it.)
