Elektor Formant Modular

If you already have the tools for making a proper pcb then the job is very
easy and I found it easier than using the Schaeffer tools. Admittedly a bit
more work in the first place getting a library of components created but
once done, the task of making panels becomes a much easier(relatively!).

There are NO alignment problems as the accuracy of the holes (which are
drilled by the pcb company for you) is good enough to mount the finest pitch
BGA and other SMT devices and so more than good enough for the task at hand.

Of course if you don't have access to a good pcb program (Protel, Eagle,
AutoTrax.........) then the Schaeffer approach is probably still the best
option.

And remember I don't recommend this approach for large panels unless you
have a good support mechanism in place. A 19" 3U panel would be about the
biggest I would go. As far as the Formant module are concerned then the VCO
is one of the biggest and I would say the pcb approach would work fine.

In closing, it would be nice to hear from an Elektor staffer as to why they
eventually stopped doing pcb front panels. maybe there is something I have
missed.
