Case Study | Cracking failure analysis and composition analysis of electronic product fixtures
If the fixture of an electronic product cracks in the screw column, the defective results will still be reproduced by adjusting the screw size, torque setting and assembly process parameters in the early stage. It is understood that the failure parts come from multiple production batches, but the raw materials are concentrated in the same batch, considering that the failure mode may be the failure of the formula process, so the quantitative analysis of the whole composition and failure analysis

The key role and advantages of vibration testing in evaluating the durability performance of automotive components
The vibration test bench can simulate the dynamic response of vehicles under road excitation, and conduct a series of controllable vibration simulations in the laboratory to test whether automotive components can withstand the impact of vibration environment during transportation, assembly, and use during their lifecycle. This can help detect electrical short circuits, loose fasteners, seal failures, and cracks as soon as possible.
