engineering joke
heatsinks for SOT-23

re: engineering joke
@Felthry oh shit, i actually got this joke, i must be getting competent
re: engineering joke
@gardevoir you know the bits of the basics that they don't teach you in school for some reason!
-F
I was thinking the same, but maybe if you're /that/ desperate for board space? O.o;
@Felthry I was thinking looking at it ... like, we were studying heat transfer in grad school, looking specifically at electronic packaging
there are, like, so many layers creating thermal resistance between the heat-generating element and the heat sink in that design ... it's kinda impressive that they managed to make it better than nothing

@packbat i guess almost anything would be better than nothing unless you use like styrofoam or something but yeah, there's... no way you should ever be using TO-92 if you need any sort of heat transfer
Even the metal version, TO-18, has pretty awful thermal properties
-F
I mean, have you seen PC power supplies? A lot of them have parts that aren't that much bigger with thermal pads underneath, and then have fins attached to the copper on the top of the board for the heatsinking. Looks damned weird.
@zetasyanthis yeah but those'll be like SOT-223s or DPAKs, which are designed to be used that way
no one uses SOT-23s when they need power dissipation
-F
@Felthry Also, the troublemaker in me wants to build a ridiculous board to prove this wrong, even though there's no real point. XD
@zetasyanthis i mean you could but you'd save yourself several headsaches if you just use sot-223s instead
-F
@zetasyanthis but augh now you have me wanting to too!!
sot-23 is a pleasant little package...
-F
they actually do make heatsinks for TO-92 though and just why
