Hello,
I think of buying a conductive pen, possibly Chemtronics cw2000 nickel pen (as it is in nice < 20e price range).
I would use it quite occasionally, it'd be more like "a handy tool to have in desk drawer" if I happen to need it.
BUT, what is unclear to me is their lifespan. Datasheet says its shelf-life is 1 year and when opened, it decreases to 6 months, after which "performance cannot be guaranteed". That doesn't sound like much.
I guess a clogged tip could be opened with some solvent, but could a pen really dry/degrade "beyond repair" in some meaningful time?
Would be sad to use the pen for couple of tiny traces now, just to notice year or two later it doesn't work anymore.
Do you guys and gals have any experiences on this?
