In the narrow sense, failure refers to the phenomenon that mechanical and electrical products lose their functions, while failure analysis is to analyze and diagnose the failure mode, cause and mechanism, and study the technical activities and management activities that take remedial prediction and preventive measures. At the same time, the comprehensive discipline that intersects with related theories, technologies and methods is called failure science. In fact, the so-called failure analysis also includes many aspects. What are the aspects of the analysis here?

Loss analysis

In fact, for the whole material, whether it really fails depends on what kind of damage it has. Some of them are internal or external damage in the process, which will also have a great impact on the use. Therefore, this aspect is also an important aspect in the whole analysis. There are many processes that will analyze the composition, performance, organization, surface, etc, Only when it is truly lossless can it be truly usable.

Physical analysis

Because substances also have their own physical existence, and people often use the physical of substances in their use, so when a substance does not meet the requirements in the whole physics, or it is physically damaged, it is proved that it can not be used. In this case, we need to pay attention to it accordingly, Scanning electron microscopy can also be used to better analyze this aspect, so this is an important aspect.

chemical analysis

At present, many industrial production is inseparable from chemistry. In order to ensure that the whole substance can meet the requirements of use in the process, it is necessary to analyze the chemical transformation and the whole attribute. Only when it meets the requirements in this regard, can its whole use be more in line with the requirements. If the whole physics deviates from the existing direction and track in the transformation, it is proved that it can not be used, So this also needs to let oneself pay better attention.

Of course, in the whole process of analysis, the accuracy depends on what kind of instrument is used and what kind of business technology it will have. Generally, this kind of analysis is also carried out by a professional third party, which can be more professional and accurate in the whole instrument and technology.

Significance of failure analysis

Failure analysis is a necessary means to determine the failure mechanism of chip.

Failure analysis provides necessary information for effective fault diagnosis.

Failure analysis provides necessary feedback information for design engineers to continuously improve or repair the chip design and make it more consistent with the design specification.

Failure analysis can evaluate the effectiveness of different test vectors, provide necessary supplements for production testing, and provide necessary information basis for verification test process optimization.
