Consider whether it is necessary to make round corners to fit in your product shells.
If you want to pay for them. You can have any shape you like, at a similar price.

Generally speaking, PCBs are made by a big sheet of fiberglass, followed by line scoring. When they come to assembly line, they will be broken up along the scored lines which are generally straight lines.

If you want rounded corners, or some other shape, the PCBs have to go to an extra process on another machine. Thus, it required extra cost.

Why are power supplies almost always made using through hole components?

Every computer PSU I’ve taken apart uses through hole components, though occasionally (not in all cases) surface mount components are found on the bottom. Don’t these have to be hand assembled? If so, why are they still doing this? even though labour costs are low in China, it still must cost less for a machine to pick and place SMT stuff.
