There are automated solder processes, including pick-n-place and wave soldering.

These are mainly for more recent SMT components,

many through hole and other discrete devices still utilize human hand soldering.

The automated processes are fairly robust, and when operating ideally can solder much better than most can ever dream to by hand.

The other side of the coin, If I'm carefully inspecting each solder joint for proper contact, flow, wetting and other standard solder practice I may catch failures that an automated process would not.

I prefer to build things by hand, vs commission a board house to build a bunch real fast for cheap.

If I was making pcb for a cell phone manufacturer, I probably wouldn't want to build them by hand...

If I'm building passive networks for microphone eq shaping, then I may hand select components and do the work by hand...
