Abstract: Electronic devices for computers must be tested carefully to guarantee reliable operation. Besides experimental work, numerical methods - in this case the finite-element method (FEM) - offer great advantages because no restrictions concerning size and handling of test machines need be taken into account. For this purpose finite-element calculations are performed to bring out an optimum test configuration for a reliable test of the weakest link of the electronic device. The test piece consists of several materials with various properties, where also material nonlinearities must be considered.
Keywords: electronic devices; finite element method; FEM; solder joints; surface mount technology; SMT; simulation; mechanical loading.
