@kjcngiopfadgiopzdfng Look for and make your own Lipowitz alloy.
Perhaps bismuth is easier to procure there. ;)

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

please tell me your watt iron?

but then the ic's gonna have all its legs soldered?? is there anyway to take out the ic fully preserved?
-
Now how do you solder it back in....I've heard of people using a toaster oven.
-
How do I know if I need the lead-free version for a device from 2004? Also, what wattage is your iron? Thanks, great vid!

It's a dream work now, it's a perfect product !

Wow, that was great, I see your out of stock on your web-site, I need to remove a chip from my graphics card, this would be great

@clone4crwproductions You could heat up the board with a heat gun and bang it on a hard surface. The heat ruins the board in many cases though. Good for getting lots of SM things off many boards in a short time

Is there a way to do this while preserving the pins of the removed IC? I'm trying to salvage an old graphics chip from a laptop motherboard, and want to reuse it in another project.

@clone4crwproductions This is exactly what this product excels at. One technique is to hold the still-hot IC with tweezers and tap the tweezers on a table to shake off the remaining solder. This works because the chipquik keeps it molten so long. You can also use a bit of solder wick to get any remaining solder.

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