Hi Rich Thanks for the intro Doug. Now to give you the fullest answer to the IEC question: No there aren't....but I could always write one.....what would you like to see in such a document? No kidding, I genuinely wonder what we would need to have in the document that would be helpful to users. If you have any thoughts, let me know - and if you do know of any groups preparing such a thing, it would be helpful to have contact details. ...and I am bracing myself to see Dewey's response to the Laser v Selective soldering issue....Yikes.
