Use SMT.
I have experienced such a problem with the SMT Mini USB B connector in the past. Meestal, the solution is to design the enclosure so that it will not allow any movement of the connector against the PCB.
As for the reason why to use SMT, SMT components are cheaper to assemble in large quantities. Als gevolg, through-hole components usually require special approval in most designs targeting mass production.

A lot of DIY video mentions about ground via. I am just very curious about its function and necessity.
I am getting a PCB manufactured for a project that I am working on. One of the parts, the A4950 motor driver, has a “pad” on the bottom, which is meant to be soldered to GND of the PCB for thermal dissipation. I was thinking about the prototyping, and I am unsure how I would go about (using a soldering iron), soldering the pad on the bottom.
My PCB manufacturer just informed me that he is facing PCB warpage issue in my simple, single sided, copper poured PCB. He says to avoid this issue he suggests to add a dummy copper patch by keeping 3mm copper clearance from all sides. Can somebody tell me what leads to this issue and what are possible solutions to this problem ?
