Jonard DP-100 High Vacuum Desoldering Pump - 13" Length Professional Soldering Tool for Electronics Repair & PCB Work | Perfect for DIY Projects, Circuit Board Maintenance & Component Removal

I really value quality when I'm buying a tool. I was hesitant towards this one because I generally prefer metal over plastic, but after doing some research I found that this style was recommended by a large number of people. The reason is because it has a much larger chamber and, therefore, much greater suction. It worked really well to get the solder off, but here are a few tips that helped me.1) I noticed it was losing suction after a few uses and I opened it up and realized the o-ring didn't fit that tight and was only lightly coated with oil. I recoated it with plumber's silicon grease (Vaseline would probably work too) and it has worked great ever since. I put it on my hand and I could feel it suck my skin in the nozzle (it's pretty powerful, but didn't seem so powerful that it would cause damage or anything). So clean and regrease if you ever have problems.2) The solder HAS TO BE HOT. I found that the best way was to apply heat, melt the solder, and then while my iron is still in the edge of the solder put the nozzle of the pump in the solder (pushing the soldering iron tip out of the way) and fire it immediately. The nozzle seems to withstand heat well and has shown no sign of heat damage. The technique took a little getting use to, but once I got it it was easy. Better than always buying tons of solder wick.3) When I was doing some research on them I came across a youtube video showing this one. So if you'd like to see it used and the size, technique etc. here's the link http://www.youtube.com/watch?v=Aw4lZGk90i4
