I seem to go through keyboard like its candy. Almost always its because I spill something on them(and even those anti-spill keyboards don't do much good).

Just a while ago I spilled some rubbing alchohol on my keyboard(near the main enter key). almost immediately the keyboard stopped responding. I took all the keys out and cleaned everything using an air compressor. It didn't do any good.

My question is why is it so easy to screw up a keyboard? Why do spills almost immedately screw up the circuitry? I do know the sometimes the liquid will get inbetween the sheets of plastic that contain the pressure sensors and that sometimes causes problems but usually isn't hard to fix. If the voltage is only a few voltages(5 volts or so max for a USB keyboard?) then how could any liquid really short out anyhthing? And thats assuming the liquid gets in the circuitry. My recent spill was almost entirely on the keys and inbetween them. The construction of the keyboard only has a few slots into the innards of the pressure sensors.

Just curious because I have about 10 keyboards laying around that don't work and it would be nice to know. I know the easiest fix is not to be a clutz but I've got better things to do at the moment than try to change that.

Thanks,
Jon


some cheaply made keyboards use a mylar bottom for the keypad buttons with an laminated conductive coating as the conductive paths. when
fluids that are able to dissolve this, you have finished
the keyboards life.
