Good question. For my DSO board I have placed the 0805 parts very close, silk outline nearly touch. I think this is still OK, because the parts are smaller than the outline. So hand soldering should be no problem, and I hope that a pick-and-place machine will work. I think if I really should consider use of a a pick-and-place machine I will convert all 0805 to 0603 or smaller and gain room. A problem may occur when the smt devices are close to larger parts like Reed-Relays, BNC-Connectors... I have not thought about this before -- but I really have to populate the board very dense, because I have about 1000 parts and size of the board is A4, 20*30cm. I think mounting the smt parts first with a pick-and-place machine and then soldering the larger though hole parts by hand should work. One problem: I have not much room for the refdes.
