The quip; All you can get! By the way, worthy answers above, especially Dave F getting a little tied up is good to see, he's always on the money otherwise. But seriously, watch for damage to other components. Example; thru hole's such as radial c

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

Hi Dave, Water soluble flux has two opposite attributes. #1: It is the easiest flux to remove. #2: It is the worst flux to leave behind on a board. As for # 1, there are many de-fluxing systems out there that are very capable of removing water
