I've looked online at PCB fabrication companies, and they invariably price their boards according to the size of the board as the primary factor.
Why is this? The physical board itself isn't that expensive, is it? I'm guessing it's because the size of the boards dictates how many they can produce simultaneously, and that's the primary limiting factor in their profitability - Is that right?
Anyway, is there a way to keep the costs down when fabricating large (~8x10 in.) but sparsely populated (~50 components) boards (other than just ordering from the cheapest Chinese factory I can find)?
It seems silly to pay $50 for a board that's only gonna have $10 in parts on it.
