Is there any chance that something like a riv-nut might be used for mounting purposes or is it just a screw hole?

Are there any plated through holes on the board? I find they usually work pretty good when the normal routes fail.

Could someone provide help regarding IPC's recommendation on Plated Through hole's --- lead to hole ratio. I can't find it in IPC-2221 and IPC-SM-782. Thank you very much

Dave, I�m talking about the 75% vertical fill of solder IPC 6.3 criteria (B), and 6.3.1 Fig 6-5. I also referred to the annular ring of the Plated-Through-Hole, being coated with solder mask. Semantics, yes I did refer to the Plated-Through-Hole (Sup

Another thing we see is solder balls (sometimes fines, sometimes larger stuff) in the vias after a misprint has been poorly cleaned, as in wiped down but not washed. They end up in the plated through holes too, but those get nicely cleaned up in the
