I have been ordering inexpensive great quality PCBs from dirtypcbs for about a year now. I have zero complaints, and they are the best bang for my buck. But...I had a small problem I'm hoping to avoid in the future. I ordered the same boards using the same gerber files each time. The board has a large connector with two board lock holes for mounting. The first order the holes came plated, and all was well. The second order the holes were not plated, and I was unable to solder the board locks to the PCB. That large connector doesn't have near the strength that it would if the holes were plated and the board locks were properly soldered in place.
Can anyone explain where I went wrong, and how can I be sure that these boards will come with the holes plated in the future? thanks in advance!
