The pre-solder cleaning of misprinted PCBs can be a completely different experience from a post-solder application. While the paper that DaveF references is excellent, you may want to read the paper by Richard S. Clouthier, "SMT Stencil Cleaning: A

Hi, It is nice with a flexible machine. But what is the cost? It sounds so nice when you see a demonstration or the alike. What I have heard about the NXT model is that if the boards becomes wider than 210mm or so, the performens drops whit about 5

a disturbed solder joint. * Extended/slow cool down ramps can result in surface texture => grainy solder joint. Second, the "BGA scaling" could be a reflection of: * Too little heat (incomplete solidification) OR * Too much heat (excess grain growt
