Habba, I don't know why use lead free capacitors and a non LF components. I do not get the idea? Can you educate me? Is this customer driven or just your company. You must use leaded solder paste for this type of process. Arman

I've never had one "float" in the wave. Have you tried waving yet to see? Anyway, glue would work, or you could place a a small weight on top, or clinch a couple of leads. Russ

Strange, the OP said they don't want to use PDF because all the manual work to get the data out of PDF and into what ever system they are using... The data books from Practical are in PDF, so no help there. Unfortunately, I am not aware of any other

I've seen the catalog of Practical and it really can be used to extract the necessary parameters (like every catalog for SMD parts). But maybe the thing I'm seaching for does not exist. So I may create it. Thanks and good luck.

Here is a thread from the fine SMTnet Archives from a couple of weeks ago, where we spoke about the topic of mixed lead-free solder with components that have lead-bearing solderability protection: http://www.smtnet.com/forums/Index.cfm?CFApp=1&Messag

I have a component manufacturer that is using Sn/Ag/Cu plating on chip caps and resistors. Does anyone have any information on compatability with Sn/Pb paste. Are any changes in profile required? Is the reliability of the solder joint at risk? Tony

The only thing I would add to Chunks comments are components like buzzers, switches etc. that cannot get wet. For whatever it is worth, ionographs, omegameters and the like use the same basic alcohol/water mix for cleanliness testing. Russ

In addition, if PBA is assembled by No Clean paste or flux, you could have some color changes un PCB, on solder joit, on component body, etc. But just a cosmetic pbm. Rgds

If you are doing small circuits, you could use glass slides http://www.hometrainingtools.com/catalog/microscopes-accessories/cat_microscope-slides.html apply conductive epoxy traces, place your components in it and cure at ~ 120 Degree C

Typically lead is plated with tin. One problem with using just tin plating is that you can grow "wiskers" over time, and potentially develop a short somewhere on your PCB. SMTA is giving a presentation on the effects of lead-free solderability.
