Depending on your D.I. system, your maximum temperature concern may be at what temperture it returns to your D.I. system. Hot water may foul you set-up very quickly. As for maximum tempertures for parts, your biggest concern should be drier section

We always apply solder paste to either the PCB pads or the BGA balls. I have found that only using liquid or tacky flux does not always ensure proper wetting of the pads. Also The BGA sits closer to the PCB making cleaning and endoscopic inspection

Drying PCB after contamination measurement for rework ?

I agree with all of the previous comments. 1) Here are a few things to keep in mind when cleaning with water. To effectively clean, any liquid must wet the surface. By itself, water has a surface tension of 70 dynes/square cm. This is relaively hig

Beej, The tool supplied works well as long as the bath is up to temp and the nozzle tip was not cross threaded when fitted. Did you apply a small amount of the anti seize paste before the nozzle tip was fitted? I have seen dry tight threads if not ap

Our cleaning process involves the assemblies being completely immersed in the water bath of the ultrasonic cleaner. The assembly has a QFP44 on it. Customer stated that when these assemblies have been cleaned with water in the past (at a different

Steve, We use the 955 version for printing with the DEK Pump Print process on two lines in high volume. We clean the stencils in an ultrasonic bath with Hydrex A+ I think diluted in deionized water at the end of 2nd shift. By startup, they are dry
