What do you know about PCBs?

Much like the famous American comedian and actor Rodney Dangerfield, printed circuit boards (PCBs) just "don't get no respect!"
When I was a young lad just starting out in electronics as a hobby, pretty much the only circuit boards I personally got to work with were those that came with do-it-yourself kits. These little scamps were single-sided (you had to use jumper wires where traces wanted to cross), and the tracks were huge by today's standards -- signal tracks were probably a tad under 1/20" wide; power traces were anything up to 3/16" wide; and the ground trace ("plane" is too posh a word) did its best to fill in the gaps. Also, everything regarding the layout of the copper was generally hand-drawn and much more "organic" in those days.
