Yesterday I accidently get Tea over my keyboard. I opened it, cleaned
everything, but it won't work anymore. I suggest now it is not from
the tea, but from a rubber connection board. I don't know how's the
correct name of it, but like to describe it:

There is a small circuit board with connections over the top. Not that
kind of femal/male things. It's just circuit lines. The other part of
the connection is like rubber. The both parts are gentlie glue
together and so the connection will work. But once you get them apart,
they nevel will work together. How's the correct name oth that kind of
connection? What's the reason? How get them together again?

Thanks in advance, Reiner (again)
