I can't assert or challenge this conclusion because we simply do not have the data. This is yet another reality of this issue: Tin whisker failures in the consumer domain are nearly 100% unreported.
Consumers are certainly not in a position to conduct the forensic work required in order to determine failure modes. My guess is that the large majority of devices are thrown out upon failure, which means we know nothing about why they failed.
Companies, on the other hand, frankly, have little incentive to conduct that research other than to use best practices during design. If a product survives a couple of years they are good. This isn't due to some dark profit motive, it's just a reality of business. You simply can't ask every single customer to send you their failed hardware for expensive --very expensive-- forensic analysis no matter their age or condition. This would mean having to manage a process involving forensics of millions of devices per month or year, depending on scale.
When I was investigating tin whisker mitigation options I explicitly sought out data from the consumer electronics domain. I quickly discovered there was none, at least nothing useful. This is why I don't think a statement such as the one you made is neither right or wrong, it simply has virtually no supporting data in either direction.
- nrp 7y agoI should rephrase. From my experience in consumer electronics, the vast majority of instances of consumers stopping using a device are not from unknown failures. They are from visible failures (including reduced battery life), software/content incompatibility or obsolescence, or the consumer just generally losing interest in the device. I should caveat though that this is in PC and mobile categories. It’s plausible that things like appliances don’t fall into those failure or obsolescence modes and could be facing unknown failures that are solder related.
- robomartin 7y agoYeah, it's hard to quantify in any meaningful way. That's why I said I am not in a position to confirm or challenge what you said and all I know is that, for the most part, we can't really make scientifically supportable statement about the consumer world (by this I mean with actual published data from an authoritative source). We are blind.
