Want to see how temperature affects certain electronics components. I know I can use freeze spray to drive temperature down. What do I do to raise tem perature? Tried soldering iron with a piece of metal attached (so the IC wo n't melt) but seems the metal was dissipating the heat so well.

hair dryer?

Heat gun.

Also use a funnel with a small outlet to keep the heat in a smaller area.
The air dryer will work if you don't want as much heat and don't have a heat gun.
Hair dryer, heat gun, or in a pinch, maybe a small butane torch. I suppose a small halogen lamp could do it, too, but you'll find light sensitivity that way. I've even heard of liquid nitrogen spray bottles (very light spray, one hopes).
If it's a small area and you don't need huge temperature rise you can use power resistors and a variable supply to heat them. Place the resistor(s) close to the component under test.

I think I should own a heat gun. Harbor Freight has some real cheapos. But I also like the idea of using another hot component nearby!
Thanks for the suggestions!

Yeah but be careful, you can melt solder with it.

Yes. Start with a hair dryer. I once bought one small and cheap, never used it for my hair, but it has been real handy for when I needed a small source of heat. I was just using it recently to set some epoxy.
But I've never seen it melt solder, so it seems acceptable as a source of heat to find a problem.

If you're trying to isolate a temperature problem to a single part, you can freeze-spray a q-tip and touch it to pretty small parts.
