Do you use SMT or THT for USB mini B connector?

This question is about the advisability of continuing to use a USB mini-B right angle surface mount connector in my pcb designs. On occasion we see one of these connectors peel back or delaminate off the pcb. Immediately the question is asked, why didn't you use a through hole connector?

Use SMT.

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 the reason why to use SMT, 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.

Can leaded BGA chips be reflow soldered with lead-free process?

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 (thus, higher temperature) process?

How can I handle missing solder mask opening on PCB footprint?

I have three through-hole PCBs that are missing front and back solder mask openings for two of the components. The solder mask (usually green) is covering the front and back solder pads. All other pads for all other parts are exposed. Is there a good way to remove the solder mask so that I can solder the components to the board?
