Havoc340 Posted August 7, 2015 Author Report Share Posted August 7, 2015 If i understand correctly the prototype case used the case as the 510 ground through the board. If using a 6061 (non cast) aluminum case, will there be any real benefit in using an external/traditional ground wire at the 510? Or is the board ground through the case sufficient for the capacity of the board? Link to comment Share on other sites More sharing options...
John Posted August 8, 2015 Report Share Posted August 8, 2015 If you run all three pads, and make sure that the geometry of the case grounding bosses matches up with the pads on the board, and you avoid corrosion related issues, then there is more than plenty of current carrying capacity in a metal aluminum case. You might want to do a (Rohs, trivalent not hexavalent!) chromate conversion on the pads if you were in production. Link to comment Share on other sites More sharing options...

John Posted August 8, 2015 Report Share Posted August 8, 2015 You can mask or machine off anodize. Link to comment Share on other sites More sharing options...
Havoc340 Posted August 8, 2015 Author Report Share Posted August 8, 2015 Thanks! I'm sure I could get away with an antioxidant grease to combat the corrosion. At least that is the plan. Link to comment Share on other sites More sharing options...
