It 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 !
do you think that we are approaching the point of electronic devices becoming fully non-repairable?
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.
