Not sure, but above a certain size there are handling
issues. I presume
it wouldn't take much to break tracks due to flexing on larger boards.
On the very large boards that I've seen, there are usually stiffeners
(metal bars) either screwed or soldered to the board for support. This
results in a board that's far more rigid than an unsupported board half the
size.
