I am almost certain that I have seen cheap, brown, production single sided boards that did not have plated holes populated with components whose leads are impossible to bend as MC suggests. May have been a VCR? In the SnPb days, I helped built single sided non-PTH boards with DB25 connectors. Hundreds were built, and as far as I know there were no failures due to the DB25 losing connection.
