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
