I'd have to agree with this. I designed an accelerometer circuit which
worked quite well. Someone else wanted several of them later on, but I
had to redesign the PCB. They worked terribly, even though it was
exactly the same circuit. The original design worked ok on the
aquisition system, and all the others didn't. The only conclusion I can
come to is the board layout.
