I've often suspected as muchIt was revealed to me a long time ago by a manufacturer that the markings on surface mount components are arbitrary for that production batch to be distinguished from other product batches. Next day can be another marking for the same device !
It depends on what you mean by 'repairable' - the never ended quest for cheaper and cheaper electronics - thus meaning no spares, schematics, or service support, looks like we're not far off now.Nigel;
do you think that we are approaching the point of electronic devices becoming fully non-repairable?
Absolutely, luckily they are generally very hardy devices.That is what I suspected.
More over, let's imagine that a programmable device like an microP or FPGA becomes damaged.
Without the associated firmware, that device becomes un-repairable.
