Magic smoke (also factory smoke, blue smoke, or the genie) is a humorous name for the caustic smoke produced by severe electrical over-stress of electronic circuits or components, causing overheating and an accompanying release of smoke. The smoke typically smells of burning plastic and other chemicals. The color of the smoke depends on which component is overheating, but it is commonly blue, grey, or white. Minor overstress eventually results in component failure, but without pyrotechnic display or release of smoke. A power transistor inside a power supply is a frequent culprit for the acrid smoke.

  • Magic smoke (also factory smoke, blue smoke, or the genie) is a humorous name for the caustic smoke produced by severe electrical over-stress of electronic circuits or components, causing overheating and an accompanying release of smoke. The smoke typically smells of burning plastic and other chemicals. The color of the smoke depends on which component is overheating, but it is commonly blue, grey, or white. Minor overstress eventually results in component failure, but without pyrotechnic display or release of smoke. A power transistor inside a power supply is a frequent culprit for the acrid smoke. The name is a running in-joke that started among electrical engineers and technicians, which was later adopted by programmers and computer scientists. The jargon file, a compendium of historical and current hacker jargon, defines: magic smoke: n. A substance trapped inside IC packages that enables them to function (also called blue smoke; this is similar to the archaic phlogiston hypothesis about combustion). Its existence is demonstrated by what happens when a chip burns up -- the magic smoke gets let out, so it doesn't work any more. The device operates as long as the magic smoke is trapped inside of it, but when the smoke escapes from it, the device ceases to operate. Ergo, the smoke is an essential part of the device and its operation, through undetermined ("magical") means. (en)
