Check flux penetration and type of flux. How much is solid contents. The solder filling is better under Nitrogen. Check the time (speed) of the nozzle whether is correct. Usually For SAC305 the temperature of bath is 320C/degrees, but only for sel

It could be lack of preheat or flux. You can verify the flux by hand applying. I'll bet it's lack of preheat though. That's usually the case with selective solder.

Thank You Michael, as I read on previous contamination related topics I planned to ask your opinion on that directly :-) but You were faster than my action :) I will share Your opinion internally and hopefully we will take further actions best reg

Hello, tried searching the SMTnet archives, but not yet a clear answer - maybe there is not a one yet ? ;) last discussion I found is few years old so maybe there is a fresh view on that? Q: we want to prove that our proces is "clean" we use SAC30

We manufacture both bulk and localized ionic contamination testers. My answer is from the perspective of the cleanliness testing method. The issue with all bulk ionic contamination testers (Ionagraph, Omegameter, Zero-Ion), is that they test the en

What are the continuing costs on the N2 generator? Is there replaceable media that needs to be monitored/replaced at regular intervals to maintain N2 generation? We're currently using tank-supplied N2, but are just getting ready to fire up our sele

Does anyone hear have any first hand experience with these systems?

With friends like you, who needs enemies? I�d guess that the perceived benefits of flat pads for your 20 mil pitch and below components counter-balance the higher cost, gold being a solder pot contaminant, limited solder mask compatibility, potentia

Does anyone out there have hands on experience of selective soldering. Either masking or miniwave type. I am looking for pointers with regard to equipment selection and known process problems/ limitations
