How much meat do you need to leave around a PCB mounting hole to ensure it is strong enough? I know it depends on the application but this is for static pro audio; not touring gear so vibration is not an issue. I have looked on the net but there seems to be no hard and fast rules. One rule I have seen is to leave one hole diameter between the edge of the PCB and and the edge of the hole. This means a 3mm holes would need to have its centre at least 4.5mm from the edge of the board. I have looked at several PCB design guidelines but none of them mentions this.
