outer layers are forced together at that point and the conductive ink
touches making the contact. In the first place, you usually can't get
these assemblies apart, they are usually between layers of hard plastic
that are heat-welded together (although I have seen one or two older
ones that used screws). In the second place, it's hard to clean the
conductive printing, and you can even rub it off. So, usually, when a
laptop keyboard goes bad complete replacement is the only option.
