| Apr 15, 2015 at 12:02 | comment | added | Hot Licks | Electronic components wear out, due to a number of mechanisms. One is simply the migration of atoms across the P-N junctions, due to a sort of "diffusion". Another is a rather bizarre "erosion" that occurs in integrated circuit wiring at the corners, similar to how "oxbow bends" form in rivers. But in most real cases these effects are vanishingly small and mechanical failure (due to vibration & thermal stress) and the failure of, eg, electrolytic capacitors are far more significant. | |
