We use a small DI water generator feeding a diaphram type pressure tank going to a standard dishwasher. We have some filters in-line also to prevent white residue on no-clean boards. I cant think of a good reason to buy a $5,000 board cleaner rather

Our Juki KE-2020 can place up to 74mm X 74mm ICs and BGA. I am have placed this zif socket before on the KE-2020 that you are speaking of. I don't think the KE-2020s are being made any longer. I know the new KE-2060 machines (that replaced the KE-
