Vibration Testing as a Tool to Optimize the Configuration of the PCBs

This paper is linked to the EU project Euripides Eureka BOB (Board on Board) which is a joint solution for companies from four European countries. Its goal is the development, design, implementation and validation of an innovative configuration of the PCBs in 2.5D arrangement, which is designed for applications with a high density of components, and must meet the requirements for reliability in harsh environment and the ability to repair. To minimize the effect of mechanical stress is one of the priorities of this new construction, where a high density of components occurs on both sides of the PCB configuration. Therefore, any new solution, especially in 2.5D configuration, designed for harsh environment, requires mechanical stress optimization, already in the board's design process. Shock and vibration tests are also essential steps to reliability and quality assurance. This paper suggests as a simple example of one possible way to achieve this goal using vibration testing, including vibration simulation...
