Abstract

The paper presents the modification of the first 6 natural frequencies for a PCB case where the material quality was modified from Ultradur B4300 G6 material in AlSi12Cu1 aluminum alloy. Following the change in the quality of the materials, the natural frequency of the 1st vibration mode changed from 164 Hz to 378 Hz, as a consequence of the change in the modulus of elasticity, respectively the stiffness.
