: :Everybody, what do you think about THIS monumental FAIL! Can you say Heavy Metal Toxicity? How about trace and joint contamination? --- Quote ---https://youtu.be/WUjxtrK1xTM --- End quote --- Who wants to employ this technique on customer repairs? Cheers, Dave |
| KaneTW:
Mercury in liquid form isn't particularly dangerous. The problem here is residual mercury causing joint failure down the line, and potential RoHS/whatever issues. E: oh, he takes a soldering iron to it. As long as the fumes are sucked off (fume hood or similar) it should be fine. Mercury vapors are not something you should breathe. But soldering in a fume hood sounds like a giant headache, and I doubt that dude's doing it. |

Fucking hell, soldering with mercury is right up there among dumb ideas. And then using a toothbrush to clean off the dross... hello ESD damage. (Solvents don’t prevent ESD damage. In fact, I saw a report about a chemical plant explosion caused by static buildup in alcohol, caused by the alcohol flow.) |
| CaveMannDave:
Kane, Thanks for seconding my objections to this method. ;Dni Tookie: i hadn't considered the static discharge aspect (goodbye expensive, perhaps irreplaceable device), but was appalled by little QuickSilver particles flying around the area. Did "he" actually recommend gasoline (petrol) for cleanup, or was that another video? Cheers, Dave |

That seems incredibly stupid.... and raw mercury may actually be harder to find and more expensive in the US than a cheap hot air gun.... and while the liquid may not be dangerous to have around, it's very dangerous to handle, so the residue on the iron, the splatters from flux boiling, the residue on the board.... all of it would be effectively hazardous waste not suitable for a landfill. Mercury's boiling point is about 350C, too, so it doesn't take much extra heat from your iron before you're breathing it even with a decent flow fume hood. They overlay "safe soldering" on the video like they're trying to reassure themselves...... the right equipment is so inexpensive, don't throw your health away handling and trying to solder with mercury. |
