The flaming obvious and yet trivial? has? just occurred. How are people going to mount the PCB as shown ?? Three hole posns at a minimum will be required for say 3.4mm holes.? Edge distances have to be allowed.? As long as it can be mounted on a bit of AL with a return on one side it can be bolted anywhere. As it stands it will have to be (hot melt glued ??) to something ..a bit like skyhooks required on some engineering projects in a way.? ?Even if people have to drill out prescribed rondels for the screw down on Rx of the board to keep the price down,? they still need to be nominated.?
