For the above test panel I specified non plated through holes in the drill file, but I’ve since come up with modified hole footprints that have the large holes specified in the edge cuts layer. Of course these would not be plated through, or at least I wouldn’t expect it. The vias obviously are drilled and plated through. I think these footprints should be fully compatible with JLCPCB’s stated capabilities so hopefully no more orders will be delayed in review like the last one, at least not for the same reason.
The hole sizes are adjusted from what I’ve used in the past in accordance with recommendations I’ve found for standard bushing sizes.
Here is my first panel done with those footprints:
Indeed the big holes are not plated through. (The mounting slots are, as was specified.) No complaints from JLCPCB (this time) so I’ll plan on doing future panels this way.
