  • Abstract
    DAB are a new kind of substrates in which the copper layer was replaced by an aluminum layer. In [1] a increase of the roughness of these aluminum layer was observed during thermal cycling tests. A similar effect was observed during power cycling tests in [2, 3]. This paper will discuss this effect with experimental results and Finite Element (FEM) simulations.
