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.

I know that using leaded process for lead-free BGA chips is not acceptable, because the solder balls of the BGA will not melt and the joint will be unreliable. But now BGA chip is only available in lead-free balls. is it ok to solder leaded BGA chips with a lead-free (dus, higher temperature) werkwijze?
I’ve ordered fabrication and assembly of small PCB batches (100st) a couple of times already. Each time the factory asked me if I want to do test on the PCB. But I don’t what to do about it. And I test them by myself. Vervolgens, the result of the testing is unacceptable with 15% soldering problems. So bad. I think I will ask the supplier to test them before delivery.
I find that the all types of PCB samples from my suppliers have ground planes. It seems important and I want to know about its function.
