The main component that produces a low melting point is bismuth, actually. A lead-free version is available.

Hi being an electrochemical tech I figured out why ChipQuik works. Simply add bismuth to any solder while the solder it is molten and the total melting point can go as low as 195 degrees F. This costs near nothing! bismuth is cheap!. John

Now how do you solder it back in....I've heard of people using a toaster oven.

hi, where can i get bismuth?

Thanks for the info! I like this idea better than another one I just saw of blowing a hot air gun over the chip which seems far too dangerous to me and would likely damage other neighboring components in the process...

Thanks I like it

The English spelling originally did not have an -l-, so there was no such letter to pronounce. The fusible alloy was spelled soudur. In the 18th century, our friends the hypercorrectionists decided that these and other words (like salmon) should show their Latin origins. Solidus was Latin for the joining agent, so doesn’t it make perfect sense to graft an -l- into the English words? Not really. The spelling was forcibly changed, but the original pronunciation lived on.

Maybe it's because we don't speak the Queen's English unless you are from the UK :)

Thanks for the vid. This stuff looks like it would make removal a lot easier.

Maybe it's because the "L" in the word solder is silent. Do you also pronounce the letter L in the word "walk", or "talk", or "could" or "would", or "half"? (I could go on with many more examples).

Hey Thanks for this video :)

Thanks for this informative video.

It is quite strange, though, to hear you say sodder when you mean solder.
