Heat Damage?

[axeman]

How vulnerable are the components to heat when soldering (replacing back and forth) "modding" Sometimes after soldering resistors and capacitors I notice they become very hot, would it mess up the integrity of the component?

Most devices have spec'd out soldering temps and times listed. The most vulnerable are caps and solid state devices. Get a good quality iron, get it, get out.

It's not a bad practice to use a heat sink on components, especially when the lead length is real short.
You can use a simple alligator clip or a hemostat is excellent as you can clamp it fairly tight and since it has much more mass, will absorb heat better.

I generally don't heat sink most component as I get on and off with the iron pretty quickly.

The power supply diodes is a good place to use a heat sink, although they seem to handle heat pretty well.
Especially if you use the bigger ones like the UF5408 diodes.
They do have thicker leads so you have to be aware of that.

I recently put some of those in an amp. I also installed .01uf ceramic caps across each one to keep the switching noise to a minimum.
This was on a eyelet board and I had to actually drill out the eyelets just a bit to accommodate the two diode leads and cap leads in each hole.

WTF!!??

Just kidding.

I generally don't screw with heat sinking components myself either. I know the heat control on my iron pretty well and like you I usually solder the joint as quickly as possible.
