Mmmm....diplomacy. I'm too. Too often. Less gastrit and good sleeping. But...there may come a big but...imagine a very big company. They have shipped equipments for billion dollars. 500 pcs F-22 for instance. And the electronics are LF according to the law. And after a year or two, failure reports begin to drop in. After 5 years hundreds of reports and after 10 years thosands. Let's play with the thought that the reason is leadfree solder joint problems. The fight begins. Who will pay the bill? The example is exaggerated and not so realistic, but you see what I mean with the responsibility matter. Can you create a contracting with the solder supplier to protect yourself against such disaster? No. Do the company insurances cover such things? I doubt. Who to blame? .....no, no, no..be silent now guys. I see what you would like to say, but I have a diplomatic discussion with Daniel now. I agree with you as far as to doing the best we can. Of course. If I go home in protest, noone bothers. I may, as best, get some admiring words from some TNetters. What is of interest, again: who will pay if you get a real kickback ? You say yourself that you got lots of negatives about LF. In my mumbling opinion, that's a little scaring look in the crystal ball! I think I've hereby got enough of philosophy thoughts on LF. Better to concentrate on practical issues, when they appear. Thanks for the response!
