I'm relatively new to PCB design. I've done small projects since I was a kid, but now I'm moving up to much bigger designs. I'm currently using the freeware version of Eagle, and am about to buy the professional version. I keep reading how the autorouter sucks, and even from what little I know, I agree. I'm already planning on spending $800 for the schematic and board editors and not having to spend another $400 on the autorouter would be nice. However, how in God's name do you hand route a multi-hundred pin package or hundreds of tightly packed components or a board with more than two layers or a combination of these? I'm working on a breakout board for an ARM9 processor in a 256-BGA package. The spacing between each ball is less than the diameter of a human hair! I've seen BGA packages with more than 1700 balls! You guys would seriously hand route this?
How do you do this? Is there some secret to this?
