I had some prototype circuit boards made containing traces that form an array of
targets for conductive rubber switches. I know from taking apart dead phones,
calculators, etc., that these switch on the circuit board are normally either
gold-plated or coated with carbon - I suppose to combat corrosion. But to save
money, I didn’t get that done on these 20 developmental prototypes. The swtich
targets are just bare traces (no solder mask). At this stage, is there anything
I can do myself to improve the longevity of these prototype boards? How
beneficial is that plating or coating on conductive rubber switch targets
anyway? Or course the production boards will be commercially coated, but I
would like the prototypes to last as long as possible.
