Pressure controlled cleaning system |
| abstract |
A cleaning system which includes a tank that contains a cleaning fluid. The cleaning fluid is typically in either a liquid, vapor or two-phase state, and is capable of removing grease and other foreign material from an object such as a circuit board. The tank has a heating jacket that provides heat to the cleaning fluid to raise the fluid to the vaporized state. A still is coupled to the tank by a vacuum pump. The pump circulates both liquid and vaporized cleaning fluid through the still which removes the foreign material from the fluid. The system has a pressure control system which controls the pressure of the cleaning fluid within the tank. The vacuum pump and pressure control system insure that the cleaning fluid is maintained in a desired state. The vacuum pump typically reduces the pressure of the cleaning fluid below the operating level of a conventional cleaning tank. The reduction in operating pressure provides a corresponding decrease in the saturation temperature of the cleaning fluid. |
