It's not just tinkerers that blow up chips that way - I have had new
units go to production (first ever run) and had parts in backwards.
With the power at corner pins, that meant the power was applied
Fortunately, the burn marks on the PCB were not fatal to the unit
(although the misplaced components had the magic smoke released).
