Lifted pad on board remedy? - DIY Direct Control of Hardware. Read Only. No more posting. - PlanetChristmas! Forums. Read Only. We've moved to http://talk.planetchristmas.com - The Forums of PlanetChristmas have moved to http://talk.PlanetChristmas.com
It has happened I think at least twice with me, where a pad will come up while soldering on a PCB. Luckily these weren't important projects and I was just tinkering around.
I would like to know what people here in the forum have done to remedy the situation or is there a remedy?
If it’s a double sided board and the connection is still made on the opposite side, then I just leave it. If the pad was connected to a trace, just connect a piece of wire between the pin with out a pad and something else that is connected to the same trace. The wire can be on either side as long as it doesn’t interfere with mounting or normal operation. Just make sure you use a wire that has at least the same cross section area as the trace.

Usually its is caused by too much heat and or overheating the area when you solder. If you are soldering a small part you should use a lower heat range on your soldering iron. This can also be caused by a dirty soldering tip.
I have soldered 8 CTB16PC boards and I use two different irons that are fixed watts. I use a 45 watt iron for the heavy work and a 25 watt for the medium to light work. When soldering you should clean the tip often. I will use a wet sponge to clean the tip while soldering. After I have completed one board I will dress the tip with a file to keep a point and remove the build-up on the tip. A clean tip transfers heat better than a dirty one.
Too much heat causes problems too little heat and the solder will not flow properly.

Hey Buddy Can You Spare A Light!!!!!!
It's not the number of channels you have!
It's how you use the channels you have!

For the "lightweight" (or standard) work if you are using a fixed wattage pencil type soldering iron 19 to 21 watts is ideal. With 45 watts you can overhead things pretty quick. I agree with you about keeping the tip clean but you could cause problems by filing. Tips are sometimes made with layers of different metals. If you file through the top layer it may not work properly.
The better soldering irons use silver plated tips. It makes the tip last a lot longer because silver oxidizes at a slower rate, though you still need to keep it tined when you’re not using it. These are self temperature regulating, and if you file them, they won’t take solder as readily, they’ll regulate at a higher temperature and they’ll wear at a greatly accelerated rate.

That's what I was trying to say. THANKS for giving a much better explanation!
