We are looking at some applications that will require fine-pitch and possibly ultra fine-pitch. I am currently using a spray type batch cleaner for cleaning our stencils. Will this be adequate for fine-pitch (15 � 20 mil pitch) applications?

Please take us through the options for processing the "waste" liquid that is loaded with solder, adhesives, and what not as a result of cleaning stencils and mis-printed boards. What are the costs for equipment, material disposal, and other items of

I used the SMTnet search at the top of the page with the keyword "bga" and dropdown component "library" and came up with 14 references. You can also do a search using "BGA" as keyword and "forum" as the dropdown component to get some insight from "t

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

I don't know where sulfur would get into your resistor supplier's process. Your processes are more likely candidates.

Well, the vendor claims the contaminant caused the component failures. So? The only feasible possibilities would be contaminated solder paste, wash water or coating -- or maybe the problem is due to defective resistors?

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?
