The application of combined experimental and numerical Fracture Mechanics approaches for material interface reliability is inevitable for the understanding of crack initiation and propagation. Experimentally determined critical energy release rates as a function of e.g. mode-mixity, temperature, etc. are required for a correct interpretation of finite element results.
For interface cracking, these values are difficult to obtain by standard methods. Therefore, AMIC has developed a new testing device, the so-called Advanced-Mixed-Mode Bending (AMB). It guarantees accurate and fast evaluation of interface properties. This enables measurements on real package interfaces under realistic process parameters and hence, furnishes the best possible result in the shortest time requiring only a small number of specimens.
