Nice to see an initiative on such a thread. The first time I went through the posting, I was not even aware of what RoHS is. After further searching on Google, I came to know that it is the "Restriction of Hazardous Substances Directive." Thanks for educating me.
Presentation on RoHS Testing Methods
I am attaching a presentation I found on the net about different testing methods for RoHS. I don't know how relevant and helpful it may be to you. Please have a look and let me know your feedback.
Hopefully, our senior members will come up with more technical inputs on this topic.
Regards.
