| Jan 4, 2022 at 9:57 | comment | added | Lundin | @Bonnevie Yeah perhaps... and if possible check it in a microscope afterwards, see if there's any copper residue. But as I said, "Seller just says it does not work anymore" indicates that the part has been powered up in this state and if there were shorts, then internal protection diodes on the pins etc could be fried. You can't fix that. | |
| Jan 4, 2022 at 9:54 | comment | added | EmilBonnevie | @Lundin So it would be best to try and clean up with a dremel? | |
| Jan 4, 2022 at 9:42 | comment | added | Lundin | Main issue probably won't be routed traces but ground planes etc getting shorted against each other. And if someone has powered it up with a short present, anything could be fried. | |
| Jan 4, 2022 at 9:39 | comment | added | winny | ”Would the multimeter test with too high voltage?” Most multimeters are designed to test with less than one diode drop of forward voltage unless you put it in diode mode. Modern super low voltage ASICs could potentially still be triggered open, but I doubt you would damage something inside it. I would worry more about ESD damage. | |
| Jan 4, 2022 at 9:37 | comment | added | Unimportant | Testing for shorts would be useless imho. There's many parallel (power/ground) pins on such a CPU which would all measure short and the problem might be a break rather then a short. | |
