The lifetime of electronic components follows a predictable trend. The infant mortality problem can be addressed by the implementation of stringent quality controls during manufacturing. SEM examination of metallization, glassivation analysis, thorough precap inspection, electrical burn-in, and DPA procedures will identify respective problems. Once past this initial failure stage, they usually perform for a long period of time with a low probability of failure. Destructive Physical Analysis DPA is performed to ascertain the high quality of parts used in the designs of space and launch vehicles.

This means that your search results will contain all results that contain ANY of the entered terms. OR: the results will contain either term s joined by OR. For example, volvo OR safety, would return results that contain the terms volvo OR safety. This would increase the results returned when compared to using the AND operator. NOT: The results will not contain the term s. For example, volvo NOT safety would return all results that contain the word volvo, and do NOT contain the word safety.
The results would include such words as aerospace, aerodynamics, etc. Using the question mark,? For example, searching for t? Conducting a search for "heat model" will return all results in which the exact phrase "heat model" is found, while "heat modeling" would NOT be included. Using double quotes can help to target your search and reduce your results.
A term combined with a phrase will be joined with an OR operator. Therefore, a search for automatic "dog clutch" will return results for automatic OR "dog clutch" which would increase the total number of results.
