IC Failure Analysis Techniques & Troubleshooting


Abstract: When troubleshooting a complex device, knowledge is king. We want, and need, to know everything relevant to the issue, including the proper IC revision number, where to find relevant reference materials, and who really knows what happened at the customer's site. Failure analysis of ICs requires a quick and proper response because, of course, helping a customer is our main concern. But should we expect the quality assurance (QA) department to test every parameter over all conditions during a failure analysis (FA)? No, not at all. Too much of that is guesswork. It may surprise some people, but QA people do not have crystal balls nor do they read minds. Timely and effective IC troubleshooting is only possible when precise technical information about an IC failure is available from the customer.
