  • Gradient dragout system in a continuous plating line
    Patent number: 6780253
    Abstract: An enhanced gradient dragout system conserves plating chemicals, including precious metals by providing a series of tanks with cascading rinse solutions having a flow rate controlled by heating the first tank to increase the evaporation rate. A portion of the concentrated solution in the heated tank is returned to the process tank. The system minimizes the requirements for clean rinse water, and the need for emptying contaminated rinse tanks with associated recovery and disposal environmental and cost issues. The low cost system is flexible and the process is adapted to the material and process requirements of the plating line.
    Type: Grant
    Filed: July 3, 2002
    Date of Patent: August 24, 2004
    Assignee: Texas Instruments Incorporated
