Pretend temperature rise

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 temperature? Tried soldering iron with a piece of metal attached (so the IC won't melt) but seems the metal was dissipating the heat so well.

hair dryer?

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).

Heat gun.

An oven and a good thermometer.

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.

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.

How does that heat the part?
