There has been substantial amount of FEA done on predicting BGA ball reliability, but this has most often been applied to assessing the reliability of the design of products, rather than the effects of rework. This sounds like an interesting proje

The sulphur outgassing from these rubber bands was >enough to contaminate every board... Well, if every rubber band is a threat then sulphur contamination must be a common problem. Are sulphur test kits available?

I posted a question regarding Stencil Drying in the OnBoard Forum and received some good feedback. Is there anybody in this forum that may be able to add to the information on drying stencils?
