Does anyone have a list of component types that can be put on the bottomside of a doublesided reflow board that will not fall off during the second pass (Or on the otherhand, a list of components that will fall off)? This would be a list of parts tha

On first glance it looks like those particular pads were not attached to any traces. If I had to guess I would say that your rework profile got hot enough to melt away the glue holding the pads to the board and they came away with your part when you

Jonathan, we do that all day. We do not use different pastes nor do we glue components nor do we run different profiles. Depends on what is meant by "small components". In our case it�s all that "bird seed" up to SO8. That will work for more parts.

Q: The question I have is do they wet in wave solder, and if they do, why does it matter what happens to them in reflow? A: Yes, but somebody here don't agree with me that the glued part need help from wave to get the good wetting. They are wrong

Yes this can be a killer. Its caused by glues with a high water content or fast curing of glues. When you get solder going through the glue it is litterally sucked in during solder wave contact. If you have never seen it you would never believe it bu

Steve, I'm using 5 Sn/1.5 Ag/93.5 Pb Solder wire with a melting point of 300 deg. C to connect my thermocouples on smd components for thermal profiling. I'm using a soldering iron with an adjustable temp. to be able to melt my solder wire. Temp is ab
