Water is known as the universal solvent for a reason. Not because it's a powerfull solvent but because it has hydrogen bonding and is bi-polar. I think it's the polar nature of H20 that makes it disolve ions. D.I. water will pick up ions where it c

Se�or Tech Put a penny in your water wash tank that uses DI water. It will disappear in a couple of weeks.

Se�or Tech If you want clean board using a dish waher, you must run deionized water. If you run DI water through a dishwasher, it will cut through those flimsy pipes like fire driven by Sana Anna Winds through dry brush.

I worked at one place where they had a dishwasher. They had stopped using it by the time I got there. But if they had kept using it I would have gotten a clean glass and put it in to see how clean it came out. I think after a while with only one tan

Solder paste used was Kester FL250M (no-clean).... components affected were only chip components 0603, no BGA & no IC components.

0603's and 0402's are being damaged by the water wash post reflow. PCA's are 1" X 4" and 2" X 2" approximately. We've adjusted water pressure so that the top-down is higher than the bottom up. The baskets have a .5" mesh spacing. Some baskets h

Is anybody doing BGA soldering water clean solder. If yes how you are ensure cleaness. We have boards with Four BGA and 2000 chip and ICs.We are processing with no clean solder but we are getting bad wetting so now we are planning to switch to water
