ABSTRACT:
A deionized water cleaning system suitable for movement as a complete unit to different locations. The unit includes an integrated rinse and sump tank where the PC boards are washed and the water is collected. The sump is sized to allow the water temperature to be lowered before leaving the tank. The water is cleaned by a filter system which includes particle filters, deionizers, and an ultraviolet sterilizer. The cleaned water is recirculated through the tank and is allowed to be diverted through an on-demand water heater when the water is to be used for washing. A back pressure regulator assists the diversion through the heater and a float switch allows for automatic replenishing of the water in the system. All of the components are supported by a platform structure which can be easily moved.
