Classic MTBF applies to repairable products. An IC can have a mean time BEFORE failure, but MTBF is generally, IIRC, applied to repairable products because it is Mean Time Between Failures.
Different manufacturers have different approaches to this parameter, but it's often a statistical value. IC's have 'em too, and you can calculate the statistical reliability of a product based on those values and the number of components. The MTBF of an IC is typically VERY much longer than that of a board containing many of them. You can draw your own conclusions from what you find on Google. I'd suggest you read the descriptions provided by various vendors. You'll see they have different approaches to this value. RE |

| Lots of work to try to get reasonably correct MTBF | 01/01/70 00:00 | |

| Yes, it's all statistical, but not everyone can do it | 01/01/70 00:00 | |
