Basic rule of thumb for lead free manufacturing: If the joint looks "too good" it probably has lead in it. This, of course is based on comparison observations of other components on your assembly.

There are several methods in IPC-TM-650 depending on whether you're testing for the effect of flux residues or board cleanliness. They're available for free download here: http://www.ipc.org/contentpage.asp?PageID=4.1.0.1.1.6

Thanks to all. I have it straightened out. We were running too hot and too fast and too long of a reflow time. I am running with Kic2000 and it works great. Thanks for all your input.

Steve, I have her book. Its a good book discussing the entire process. If you are looking for a book strictly discussing solders, then it would be too broad.

Is your oven suitable for Lead free temperatures & can it achieve a decent profile across your complete range of boards? AOI will need to be looked at too as the joints are not as shiney. Cheers, Rob. PS. Where's Thisbie?

Is there a standard that we should aim for in respect to the strenght of the solder on SMT leads? We have a customer who are testing our product by pulling leads off of pads then returning them.

Dougs: What is the purpose of this test? Lately, we have had a lot of boards that do not withstand the Drive-Over The Board With A UPS Truck Test. We wonder is the is some relation between our test failures and your customer's.
