Thanks for all the feedback - some very good info! Masking As to all those who indicate masking off the metal what about oxidation? I'm concerned about the appearance of masking off the painted areas. Can the screw be coated after assembly? Hard to take apart for sure..........
I have some problems with masking. I have no issue with the electrical/mechanical principles.... But it seems that the appearance will be very poor and the effort to accomplish high. I suppose that is why plated surfaces are preferred...... What about conductive paint? Too expensive? Appearance?

But I hear it's held up in the test lab due to some problems with the star washers they're using or somethin ... - Doug McKean ------------------------------------------- This message is from the IEEE EMC Society Product Safety Technical Committee emc-pstc discussion list.
