"Not all the way through hole" in PCB
(1/3) > >>
codingwithethanol:
I was working on a PCB design, and I found that the switch I had chosen has little plastic support feet which protrude into the board. This translates to having 2 little holes through the board which interfere with the silkscreen design on the opposite side. I was wondering if you could specify that a hole not be drilled all the way through the board, just "half way". I googled PCB half hole but that's used to mean literal semicircle holes.

Why, our gracious host Dave's latest video was on the very topic of PCB fabrication options! Have a watch, starting at 58:40 or so.

It's usually called something like Z-axis milling or controlled depth drilling, and it's a rather expensive extra. Maybe it's better to just take snips to the support pins, choose an alternate switch, or leave copper off that area and machine the holes yourself upon arrival.
codingwithethanol:
Thanks! I'll either trim the supports or just leave it be. Appreciate the info.

I assume it is for the aesthetic of the badge? If so, maybe make it as a VIA and then tent in on the backside if you want it cheap
Frillo:
Those are guide tabs, which also serve the important purpose of providing mechanical stability and robustness. Without them, the part might easily break off when "switched".

It's no problem to use (non-plated) through holes for the tabs, in fact I think it's the norm.
