In my experience, solder balls are normally caused by only a few things. In order of likelyhood: 1) Water based fluxes (VOC-Free)not having the water carrier completely dried from the board before going into the solder. I.E, too fast conveyor spee

John, I'll throw my bit of confusion into the pot, here. Your limited floorspace, coupled with your technology mix vs. volume mix narrows the scope of your search. You don't say what your budget is, or whether you are looking for speed. I'll give y

Jaqueline There are so many variables in the electronic assembly manufacturing process involving more than 12 different chemistries, that it is impossible to easily identify and determine the nature and reason of such residues. GEC Hirst Research in

Several points are: * There�s quite a bit of background on IMC in the fine SMTnet Archives. I�ll try not to duplicate it. * If you have a smooth and well-formed solder connection using fairly common materials, you assuredly will have IMC. Any evide

There is no specification for �Ion Chromatography for Ionic Cleanliness�. The performance of your product in your customer use environment determines the level that you select. The good part for you is that have at least one pole that you can put i
