We use our ultrasonic stencil cleaner. Before we change the wash solution, we clean pallets, chains, fingers, etc. It does a good job and takes only a few minutes.

James: So, why don't you clean your no-clean? At least then you stand a chance of doing class 2 and class 3 work.

Hello. We have a low profile LCC on a board. The clearance is ~ 2mils after reflow. Cleaning away residual flux with an ultrasonic 50C water cleaner caused some LCC and 0201 components to loosen. Should we stay away from the ultrasonic cleaner?

I need active solder paste to overcome solderability problems - I believe it have to be washed out, the issue is not the cleaning process only the paste (flux) activity level.

Anyone have experience soldering Lead-free components using leaded solder paste? I'm specifically interested in lead based no-clean solder paste. Any special concerns for reflow? Kyzen Cleaning? Thanks, Greg

we will be using water soluble solder paste. cleaning will be for smt assemblies only. waste water will be treated prior to disposal. as far as testing for cleanliness, any suggestions or recommendations on test equipment would be greatly appreciated
