The solder adheres to the lands very well so i don't think that problem is with solderability of the PCB. Not wetting to the 0805 terminations. When the problem appeared with the 0805 we chenged the supplier. But there was commnon element Pb-free te

we get paid scrap value for old solder so its better if its disposed of in the current way.

You could have a supplier problem. We had a similiar problem with one of our capacitor suppliers. I would suggest doing a solderability test on the component right out of the tape.

have you checked the registration of the component prior to reflow? If this is good, why don't you take another P/N (0805)that is okay and place of few of them in the trouble spots and see what happens.

The issue may not be the solderability protection. It could be that the metalization on the component terminal or the metal of the component terminal was not prepared properly before the solderability protection was added.

Have you tried doing solder dip test on these components? Or a Leaching Test, to see if the solder catches on the termination ? I suggest you should try these tests.. Cheers Indy

Is it now acceptable to discard the SAC alloy directly into the trash or is it still a requirement to dispose of through hazmat procedures. Seems to me that we can now just chuck the old paste right into the normal trash since it is the replacement

It would depend on your jurisdiction. ROHS is european. You would have to check with your own country requirements. Even your municipality might have restrictions, not to mention your state/province. And don't look for logic or consistancy in poli
