Abstract
In this paper, the Advanced Mixed-Mode Bending Test (AMB) is presented. The AMB is an experimental method to determine the effects on the critical crack propagation in bi-material interfaces that exist in electronic packages. Target in the development of this test rig was a quick and cost-effective data collection in addition to easier handling of samples. By two independent load components, shearing and opening of the boundary layer, a large range of the mode-angle can be determined. The test rig is designed for bimaterial beams, which are industrially manufactured, e.g. produced through laser cutting. Another preparation of the test-specimen is not necessary. It can also be used cutouts from actual products. Thus it is possible to examine influences of the production line.
