Hirose offers a Micro-B USB receptacle ZX62D-B-5PA8 as SMT + DIP. This doesn't really make sense to me, considering that the electronic contacts are SMD and the mechanical pins are just 0.8mm deep, less than many PCB. I verified the pin depth in the IGES 3D model.

How is this mounted, i.e. how are the mechanical pins utilized?

SMD offers very little mechanical strength, and there is a fairly common failure mode for SMD microUSB connectors. Plated through holes for the case improve mechanical reliability.

    \$\begingroup\$ +1. Signal contacts are SMT, mechanical pins are throughole. This is not uncommon with USB connectors. In this case, "DIP" is a bit of a [Japanese?] misnomer. "SMT+throughole" would be more accurate. \$\endgroup\$ Jul 6 '13 at 18:23

    \$\begingroup\$ But the mechanical pins are a bit short (0.8 mm) for through the hole, no? \$\endgroup\$

    \$\begingroup\$ @feklee Long enough. The pins will still hold the mechanical loads. You can still solder them. \$\endgroup\$ Jul 6 '13 at 18:27
  • \$\begingroup\$ @NickAlexeev Thanks for clarification. Judging from the picture provided by Hirose, I assume that's right. \$\endgroup\$
