I am in the process of laying out a new PCB for the Mondo Superprobe. I have been attaching the tip/needle to the PCB by soldering it to a 10x20mm foil area on the board.
Will this corrupt readings? I am thinking that the foil would act less like a capacitor if there were no ground plain on the other side of the board. Is that good enough or do you think I should epoxy the needle to the board and do away with the 10x20mm foil?
EDIT: I have added png's of the top and bottom. This is my first attempt at this layout and there will be problems so do not try to build from it. I will be increasing isolate.
