It's very difficult to communicate this kind of thing via text, and if you're going to put it in some sort of drawing, you might as well just put it in the actual design tool to begin with. You can probably see why the PCB support wanted this in gerbers now. This way, when you tent the via, the hole will be filled (so you don't wick solder), and you still save space (although not as much) Move the via out of the pad, so that the drilled hole itself does not overlap the SMD pad.Leaving the via exposed, and just add lots of solder to those pads, expecting it to wick into the via.If you must do this kind of thing, there's 2 things I'd recommend: This will make soldering the pad difficult in a best case scenario. The problem here is that if you're putting a via in a pad, you can't just "fill" the via, because the solder resist will impact the normal SMD pad you've merged it with.


It's a special process, and usually costs extra (by a lot). This is, confusingly, sometimes referred to as "via in pad", but it's not directly related to simply putting a via in a pad. This is a process where a conductive material is pushed into the via, and then it's given a flat surface, so it more or less acts like a normal SMD pad. "Filled" or "capped" vias are most likely what you're picturing. "Tented" vias refers to covering vias them with solder resist (the epoxy-like material), making them inaccessible and not exposed. This could be the wrong terminology, depending on your exact expectations here.
