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.

独立外载荷作用下界面临界能量释放率Gc(含混模角Ψ)的实验-数值表征

本文介绍了先进混模弯曲试验(AMB)。AMB是一种测定电子封装中双材料界面对临界裂纹扩展影响的实验方法。除了更容易处理样品外，该试验台开发的目标是快速和经济有效的数据收集。通过边界层的剪切和打开两个独立的荷载分量，可以确定较大范围的模态角。该试验台是为工业制造的双材料光束设计的，例如通过激光切割生产。不需要对试样进行另一次制备。它也可以使用实际产品的切割。因此，可以检查生产线的影响。
