Will scavenged parts survive soldering? Answered

If I pull components out of, say, a dead radio, will those components survive the heat of resoldering? Considering they've already been soldered once, and the leads clipped short, are they still REALLY viable?

Transistors are extremely heat sensitive.

These things aren't that sensitive, they will usually work. L

The stuff you salvage probably works unless they went way to hot and melted. Besides that, they should be fine and dandy.

My worry is ICs primarily..I've mucked a few along the way by "warming" them too much (no visible damage)...although in general your point is right on track

You can buy a soldering heatsink from Maplins that will help to take the heat away from the items you are desoldering. It's all good fun! Goodluck!

Be careful in desoldering as well, because they can of course be damaged by the desoldering process as easily as when soldering them into a new construct.

Yes. They should be fine. I've scavenged and resoldered loads of LEDs, capacitors and switches and they've all been fine after. Because they have shorter leads you just have to take more care resoldering them as they're really fiddley. :(
