Good morning all,
we request our plating supplier to coat parts to this spec.
From our understanding the thickness should be between 12 to 20 microns to be acceptable.
We believe that this is in any individual place on the part, other than bent areas where you could not get a ball of 20mm into.
Our supplier is informing us that the thickness measurement is an average reading accross a face?!?
E.g. on a flat plate we have readings of 30um on the edges but in the middle of the part we have readings of 5um?
We believe that this is a failure, but we are told that the average is 17.5 and its ok.
Any advice would be gratefully appreciated.
