Maybe someone can correct me here, but I think we're moving into the future where most components won't be marked at all. These days I'm seeing ever more often even basic things like SMT resistors without any label.
Most device vendors actually don't want the markings on components: they make reverse engineering of their designs easier (you commonly see markings on key chips scraped away because of this).
For vast majority of electronics, component-level repair is not done anymore. Even for expensive devices it's cheaper to replace the whole failed assembly than pay someone to hunt down the failed component. So there's no benefit for service engineers either. Manufacturing is all done by machines where you only need to identify reels, not individual components.
In this view, markings on components are just an unnecessary cost for all parties. I'm not happy about it because it makes electronic things even more unserviceable after they are no longer supported by the manufacturer, but I think all incentives are in this direction.
- adrian_b 5y agoFor something that has already been produced for some time, the markings may be no longer useful for the manufacturer. However the first batches of boards for a new design, or after some design changes of an older product, frequently have assembly mistakes resulting in obscure bugs that are much more easy to solve when the devices are marked.
