"What worries me is that a lot of people speak about what they have heard, but there is no firm facts on exactly what the situation is." I do not understand this reply, because what can we do beside listening & read, unless we sometimes ourself do t

From what I have seen some component terminal finished have a problem due to storage also. I have seen pure nickel finished turn black. I have seen silver barring finished have problems too. It all depends on how you chose your process, PCB plating,

Do not believe every thing your suppliers tell you, even a written cert does not guaranty compliance. We recently purchased a Niton XRF analyzer. The first day in use we found component�s that were made for us "RoHS" that were far from compliant. Peo

At my last employer, we ran a number of tests to make a "Hybrid" profile work (same profile Joe lists) . It worked great for everything but BGAs. The problem (6 months ago) was using parts not rated for lead free reflow temps. As the market fills wit

individual components are not part of the RoHS directive so Dave is right part suppliers can ship them forever, they may not be able to sell them to anyone, well not legit anyway. Distribution of manufactured goods that are already in a warehouse in

Steve is right, why risk cross contamination and suffer real legal battles from your RoHS customers you guarantee lead free to. Al is also right. If your customer knows they are pulling the wool over the RoHS watchful eyes, why would you want to

I still think the best bet is probably an SMT pre-bake operation to ensure that there is no moisture in the board. Vapor pressure is usually the leading cause for delamination, so removing the source should significantly help out. Unfortuantely, pr
