Problem with USB mini-B surface mount right angle connector
Yes, I have experienced such a problem with the SMT Mini USB B connector in the past. Usually, the solution is to design the enclosure so that it will not allow any movement of the connector against the PCB.

As for why use them? SMT components are cheaper to assemble in large quantities, as a result,
through hole components usually require special approval in most designs targeting mass production.

In my design, I replaced the SMT Mini USB with the TH version.
