Zusammenfassung:A symmetrical, flat laminate structure used to minimize variables in a test structure to experimentally gauge white bump sensitivity to CTE mismatch is disclosed. The test structure includes a flat laminate structure. The method of using the test structure includes isolating a cause of a multivariable chip join problem that is adversely impacted by warpage and quantifying a contribution of the warpage, itself, in a formation of the multivariable chip join problem.
