There are other methods. One is to laserprint onto special (or not so special) paper, then iron it onto a cleaned PCB to transfer the toner to the board. Soak in water to remove the paper, then etch the board. The toner is a etch stop.

I've never gotten good at that method. The nice thing about the photo method is it's easy to crank out another board, or many boards, with consistent quality.

I'm going to put a socket on my LCD instead of hard soldering it to my board. This will be a test bed and I suspect I'll need/want to take it apart and change component values.
