Clarification of Question by lujie1986-ga on 24 Jan 2005 10:01 PST

the ribbon cable I mean is the simplest form, which is a bundle of
them fixed on a board parallely

You need to narrow down your envelope. There are many types of ribbon
cable, and just as many ways to use them. One could write a very large
book on the subject.

If you could specify, I or another can advise.

What I mean by ribbon cable is a bundle of parallel ribbon cables on a
big board, the simplest form

Hi lujie1986. I?m afraid there is no ?simplest form? of ribbon cable
usage so there is no concise comment which can be made. Is this by any
chance a high school project?

One would suspect you are thinking of computer floppy / CD / HD etc
ribbon, 0.127? pitch, but they now differ in configuration. If
digital, what data rate are you interested in. But you might be more
concerned with analogue -- and the frequency range would have to be
specified. Then again are you considering driving and matching to the
characteristic impedance with alternative wires being grounded, or
driving into high impedance with no guards? One cannot assume though.

If you can narrow down the specifics, I (and several others) could
help. If it is a high school project and you are not able to be more
precise because it?s all a bit new to you, then I?m afraid the project
is at present too ambitious.

But we will be pleased to help if we can.
