if opens in same aria check for mask to via coverage for that pad. We had vias pulling solder from pad. We did not have totally opens but capalry from via was as strong as capalry to ball / pad creating small joint aria.

GS, What should be the temperature we should get down to? Is it room temperature? Then it could be quite a long time. Eutectic solders cool down below 183C and may be cooling to 100C should do good? What do you think?

You mean if I bought that material in USA or Europe It will be expensive. If you buy those material in places where labor is cheap then you get cheap prices with same capability. You are really missing something....

The lead free debates are getting more and more interesting Didn't know that low labor cost was also lowering melting temps of LF alloys

Are you following solder paste manufacturer's spec?? I know still some time it is hard to maintain slope particularly with less zone reflow oven.

I am looking into a pcb washer/cleaner for misprints etc. If you are using one, which would you recommend? We use no clean solder and will use lead free in the future. Thanks

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
