Hi Phil! As your "cynical brother in soldering" I have a question - " Do
you know that the RoHS compliant Irradite meets the same functional
requirements as the noncompliant Irradite?" Did you conduct any testing or
are you using supplier data?

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.
