Can a potted subcircuit be reflow soldered? If it can't, this would be a major drawback. More and more ICs these days come in LGA or similar packages that cannot be wave soldered let alone hand soldered. Components that cannot be reflow soldered on the same board would add to manufacturing cost significantly.
