We have several recent letters on line here claiming that it isn't easy to determine RoHS compliance, Eugene, and that's probably true. But the first step is to contact the vendor (Macdermid in this case) and find out whether a particular process is intended to be a hexavalent-free process. I don't know in the case of Iridite 7P, but Macdermid will either tell you that,"yes, this is one of our hex-free processes" or "no, please use Iridite XXXX instead".
