This may be outside our groups purview, but I'll ask it anyway. For our aluminum chassis sheet metal we have historically used Yellow Irradiate. The information I'm getting for making this RoHS compliant is to make sure the plating vendor used trivalent chromium rather than hexavalent chromium for either clear or yellow irradiate. It is also my understanding that there are similar "rules" for zinc plating. The real question is, how do I specify this on my assembly drawings and purchase orders? Am I going to get a true RoHS compliant plating? I can't be the only person with this issue! I'm sure I can go into did the plater have a dedicated RoHS plating tank, is he telling me he complies but in reality he just lies? Hey, I'm a cynic.
