I would like to create a printed circuit board (PCB) which is not flat and which is not shaped into a square, but don't know how to proceed. Can Cadsoft Eagle create such a board? If so, how? What other software packages can be used to create boards such as this? Where can I send such a board for manufacture?
Furthermore, I want to create a piece of plastic which has a three-dimensional shape and onto which the printed circuit board will fit. What's a good way to design both the board and the plastic such that it's easy to ensure they both line up?
