G'day all, Does anyone have a SonoFlux 2000F fixed head spray fluxer? If so, can you please give me feedback on the quality of flux coverage and topside fillets as compared to a reciprocating head system. We are in a position where we need to spen

Fixed spray head performance depends on board width. If you are looking for complete top-side hole fill, the flux penetration into the lead-hole will be more in the center and less on the ends because of the fan pattern spray. For board widths over 6

Hi All, The method that I use when training operators is.. a visual aid that shows the operators what way the trays are placed into the machine and the polarity of the component and also the component change logs. The matrix trays that I have delt w

First off, why do you feel you need to check paste viscosity ? I thought checking paste viscosity was a thing of the past ?? If you are having paste viscosity problems then it's time to get a new paste supplier. Any of the main paste suppliers have g

50% chance his boss has heard of (or maybe even one time seen) delamination and wants to be sure they don't have that problem. His boss probably felt a need to specify a test and that was one he had heard of. Personally I would recomend find a way f

Do you have a cube down the hall from me? I think it's already been forgotten, but when blindsided by these requests one has to do SOMETHING! I blasted one in reflow and did a 7 second solder bath dip with another and took pictures, nobody has asked

Thanks for the input. Currently we have the advantage of having almost all SMT operators trained in advanced programming so we are able to make changes easily to feeders, etc. Many of the things you mention we do at this time so it's funny to see t

First, while black pad can be a problem with poorly controlled electroless gold [search SMTnet Archives for background], it is not a suffiecient reason to use electrolytic. It's the reason the supplier should fix their electroless gold process. Se
