Yer not making this easy. What kind of flux? If no-clean flux, what controls are you using to assure you are: * Applying the correct amount of flux? * Properly activating the flux? If water washable flux, talk to us about your cleaning methods and

hello everyone, i'm looking for a spray gun that can withstand flux aggression. I made air controlled prototype for ersa wave machine, but air guns wear out quickly and start to leak. I was thinking about Binks model 95AR or something with stainless

Using a flux pen sounds like a good idea. Comments are: * I assume you�re talking aqueous flux. If not, some NC flux pens leave white residues. Nearly all of 15 samples suffered to varying degrees with white residues. * Use the same flux that you

Wes, I have been involved with many customers changing over from an alcohol based no-clean to a VOC-free process. The change-over can be made easier by such things as air movement, convection preheat, "drains" or reliefs in pallets (if used), contr

You have a lot to think about! What does the flux manufacturer recommend as far as specifics like water temp or pressure? Do they recommend high temp di-water a detergent or saponifier? Do you currently have a cleaning machine, batch cleaner or inl

I don't believe you'll get an exact zero flux with no-clean pastes. Water soluable yes, but I don't see it happening with no-clean; at least not this year. As for spatter, you should be able to control this. Can you define what you call "spatter"?

Talk about bucking the trend!!! OK, OK, I know some US military work still requires RMA. You�re both correct. Cleaning decisions for RMA fluxed boards are based on customers requirements. [Some do (clean) and some don�t.] Older US military speci

Hi I am using selective soldering to dip soldering the connector pins to the PCB and would like to know your experience: a) Is there a recommended dip or dwell time for the dip soldering? b) How do we improve the solder coverage in the TH? c) How t
