When complex electronic components don't work, it's important to understand what's really wrong and more importantly, why. All branches of quality control revolve around reducing the level of errors in manufacturing. Damaged chips not only lose money directly, but can also lead to unexpected lawsuits. To get a clear idea of this problem, inappropriate components are sent for inspection to the failure analysis laboratory.
A failure analysis laboratory is a place dedicated to finding out why certain chips are damaged. Over the years, the field of forensic engineering has grown to the point where there is a systematic way to trace to the root of the problem.
Electronic Failure Analysis Laboratory
Although there are many failure analysis techniques to find out why certain chips are damaged, the analysis doesn't begin with them. Instead, the first step is to find out more about the defect by analyzing the error report, error rate, failure history and error circumstances. In this way, the lab can extract important information about errors that can determine the source and what problems have occurred.
Therefore, even before the laboratory put the chip under the microscope, he had a general idea of what to look for. This makes it easy to choose the correct analysis technique because each type of analysis reveals a different error. Stress errors, for sulfur analyzer indonesia example, cannot be detected using microtermography techniques. The idea is to save as much time, energy and money as possible and increase the efficiency of detection techniques at the same time.
A good lab has technicians who really understand how chips work. This expertise is needed for many failure analysis techniques such as the Fault Tree Analysis (FTA) developed by Bell in 1962. Only when we have seen all the information available, we begin to apply scientific analysis techniques that normally use a failure analysis laboratory. famous for.
Such laboratories also use their expertise with previous situations to make recommendations about why specific errors were caused and what can be done to prevent them. Sometimes it all boils down to human error at some stage of making and in this way, the process is very similar to detective work. Quality control in making chips is meaningless without a good failure analysis laboratory to support it.
Summary
The failure analysis laboratory performs the main function to determine why certain components of electronic equipment do not function. Even before the component, say a chip, is placed under a microscope, the error report, the error rate, the history of failure and the circumstances surrounding the error are examined. Only when the information has been considered will the scientific analysis technique be applied to the chip. The main objective is to find out why certain mistakes occur and recommend what should be done to prevent them.
