【Abstract】This paper focuses on the failure problem of integrated circuits inautomotive electronic products. Takingacertain profesional technicalserviceplatform project asanexample,itcomprehensivelyuses methods such as appearance inspection,functional inspection,non-destructive testing,and destructive testing to testthesamplechipof theinfrared detection module.The failure modes identified were solderball voids,solderbonding atthefet,warping, etc.The failure mechanisms were related tothe weldingquality,internal stress,circuit bridging,etc.Through thermal stresssimulationverification,itwasfoundthatthestabilityoftheassemblyandwelding processafectsthe welding quality,and a high parameterdrift rate willincrease the product defect rate.To this end,improvement measures such as strengthening processcontrolandadding high-temperaturebakingprocessesare proposed toefectively eliminate therisk of product failure and increase the domestic production rate of chips and project benefits.
【KeyWords】integrated circuit;failure;non-destructive testing;simulation verification
