Considerations on a Smart Strategy for Simultaneously Testing Multiple PCB Assemblies in Board Level Vibration

Board level vibration test method of components for automotive electronics: State-of-the-art approaches and challenges

“…It includes board designs that can contain 4 components and 1 component on the PCB to allow homogenous stress transfer to all stressed components on the board. 1 component test board design enables understanding of stress applied to the solder interconnects [36]. Investigations with 12, 7, and 5 component board layouts can also found in [37][38][39] respectively.…”

“…Otherwise, boards might have different mechanical properties that induce distinctive stresses onto the component. This part is studied by Thukral et al [36] and limited strain variation from PCB to PCB is reported.…”

“…One such example of a vibration test fixture is reported in [36]. Vibration fixture characterization results showed no distortions at the multiple PCB mounting locations.…”

“…Several PCB mounting structures that allow simultaneous PCB testing can be readily found in literature [36,39]. Besides [36], there is not much data showing the impact of this mounting structure on the stress transferred onto the component.…”

“…In [36], three vibration test methods (1D, 2D & 3D shown in Fig. 6) have been compared by measuring the PCB vibrational dynamics.…”
