How to De-solder Electronic Connections

Video Transcript

" Hello! This is Ross on behalf of expertvillage.com. De-soldering something can be an adventure in itself. Now if you have a simple connection like this. You can just heat it up and it will fall apart. See how that snapped that is why you want to be wearing safety glasses and trying not to put pressure on something except enough just to pull it apart gently. Because that will throw molten lead around. Another way to de-solder is using little vacuum pump like this, what happens if you compress the spring. When you push the button, it sucks the air from there. So when you get the lava or lava the solder molten, they can actually suck it up here, as a matter of fact if you look at the components inside you will need to take it apart from time to time because it sucks up solder. It is simple lowering on it and it compresses down since it is just a plunger. Now they make electric ones with a pump that you push the button on in the tip is metal. So it is the soldering iron itself, so instead of using a soldering iron and this vacuum pump use one device that has a hose on it and you start up the vacuum pump by pushing the button and this tip is hot so you can just melt it and as it flows you go and it sucks it up. And it is great for using a de-soldering iron especially on a board where you have components connected together like this. You have the… if you had actual PCD and a circuit board look at that clip. You would have already traces and pass part of the board and so the components would be soldered directly to those traces as they can come through the hole. And you can use the soldering iron to determine the soldering for those. Another device is what is called the solder wick, the wick is the braid that lays over the top and heat the wick as it heats up, it heats the solder below it and sucks it up. Here I am going to ahead and de-solder this piece right here, that is going to get it flowing and when it flows and I am going to push the button….and it started to flowing now. There we go and the fact gets clean dropped right out of there and see the solder is gone and the solder went in to this thing and there it is a pop back out the end. I can pull most of it out. It could be a new type of art."
