It is worth pointing out that a very large fraction of all electronics failures are not semiconductors but electrolytic capacitors. People are often astonished when I tell them, that a "long life" electrolytic capacitor is one which will last one year at its rated temperature, whereas a standard consumer-grade will last only a month. To add insult to injury, many of them have rated temperatures of only 85°C and much of the discount electrocrap uses 55°C grade.
