    42、he supplier shall perform a DOE utilizing response surface analysis to determine the Process Window of the system. The three variables to be included in the design are Bake Time, Bake Temperature, and Film Thickness. An initial screening experiment should be run to determine what level will generate

    43、 a window which includes testing to failure. This screening experiment should be reviewed with the Materials Engineer to set up the final DOE. Response attributes to the DOE should be based on the materials tested and should be chosen from the following tests: adhesion (para 3.4.1), water resistance

    44、 (para 3.4.2), stone chipping (para 3.4.9), and high performance adhesion (para 3.4.11). 4.
