Need to do a little desoldering and don't have (can't find) an iron?
The purpose of this instructable is to show how you can remove solder from a board when you're in a pinch.
Let me know what you think of doing it this way or if you have another method...
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: First Things First
Here's what you'll need:
1) Something you want to desolder
2) a piece of wire or two
3) tinning flux would be nice
4) a soldering iron
5) wire strippers
I'm using a strand from a piece of cat 6 cable I had laying around. All I had was solid, but I'm guessing the stranded type might work even better (like copper braid).
Strip the wire back a couple of inches and get out those pliers.
Step 2: Bend the Copper to Your Will. It Will Do Your Bidding.
Start with a small bend and go from there.
Be sure to leave the bend kind of open. You want a little wicking action going on (or is this capillary effect?) to get that solder away from the board.
Step 3: Tin It Up. Suck It Up.
Put a little flux on your wire like you are going to tin it.
Press the shaped wire down on the solder to remove and press the soldering iron on top of that. You are basically making a copper sandwich with the board on one side and the soldering iron on the other.
Sorry about no pics for this part. This took both hands and I'm a little clumsy with a camera in my mouth. (excuses excuses)
Oh yeah, be sure you hold the wire at least three or four inches back. As it is copper, it can heat up a little quick. If it heats up too much though, you are probably keeping the heat on it for too long!
If there is still solder on the board, just snip your wire back and do it again.
Step 4: Just Like New.
And there you have it!
After a press or two, the solder has cleared off the board and out of the component hole.
