thanks Rob, that really explained a lot to me. I definitely understand why it is important for the european countries. I never really thought the directive was bad in it's intentions. But you are right it is the implementation of this that is a f

Darn Rob you're brilliant You just solved the dilemma of micro cracks and hot tear in lead free, just add a softer metal like.....and the joints won't crack. You wrote "BTW: Lead is far softer & dissolves far more easily than copper or tin, hence wh

Rob It's documented that lead doesn't leach out of landfills. So, how does Eurolanders health become affected by lead in landfilled electronic products? Isn't the potential for lead poisioning from using leaded glass greater a danger? Given that

Does any one out there know if CSM84V and CSM84VZ can do 0402 parts ? If so, do they actually make 8mmx2mm feeders for these machines. I've had someone tell me they do, but i can't seem to find those feeders anywhere. thank you

Inds, It's about time that lead-free components can stand higher temps "myth" stops. The only difference is the plating, the component itself has not changed. Can you give us an update on this threat? If you�re the same inds http://www.smtnet.com//

So, it looks like the backward compatible of BGA statement is not guarantee for solder joint reliability. It doesn�t matter what temperature and what melting sequence we have in order to avoid the solder void issue. Is Pb diffused homogeneously thr

At my 2nd company, I had a design EE come down, look at his product running down the line, looks at the reflow oven... He scoffs sarcastically...and then says, "What the hells so hard about this...you're just running it through an oven." Process an

We had one mechanical engineer from a certain customer telling us we had to crop components leads so they didn't protrude through the board, as they could then come in contact with the case as the board was flush. Had I have known then what I know

I feel your pain - we do the same. My favorite: no extra panels or boards for profile and due to the fact that we're behind on an order, a first article of a fairly complicated board goes from 10 to an order for 500. Myself and production takes th

I had one SMT process engineer using rubber bands to hold a connector on second side reflow. Even the operators told him he was nuts. The zero stick through on leaded devices has come up several times for me. We clip leads first and pin in paste t
