Introducción
Newer generations of many electronics have batteries that are soldered directly to the logic board. This makes replacing the battery a much harder feat than older models, who use connectors to attach the battery to the logic board. This guide illustrates the various levels of difficulty in soldering, and teaches the technique of soldering three types of connections commonly seen in electronic gadgets:
Step 1: Beginning — Large thru-hole components, such as cylindrical capacitors;
Step 7: Intermediate — Small thru-hole components, such as battery leads and resistors; and
Step 11: Advanced — Small surface-mount components.

-
A capacitor was already removed from the two solder pads. Each pad was heated while the capacitor was pulled away from the board.
-
-
-
To solder each connection:
-
Place the tip of the soldering iron against the solder pad.
-
Melt just enough solder onto the solder pad so that the capacitor's contact lead holds firmly in place.
-
Remove both the solder and the soldering iron tip from the connection as soon as enough solder melts onto the pad.
-
-
-
The leads were removed from the solder pads by heating the joint on the top side of the board, while pulling out the leads with a pair of tweezers.

-
-
To de-solder the joint, place a solder wick on top of the existing solder ball and press down on the solder wick with the soldering iron.
-
Once the solder melts and flows into the wick, remove the wick from the joint.
-
Repeat the same procedure on the remaining leads.
-
-
-
To solder the new leads to the board, place the bare end of one lead onto the bead of solder on its corresponding solder pad.
-
Press the tip of the soldering iron onto the solder bead until it melts.
-
Slide the exposed end of the lead into the liquid solder until it is in the center of the bead, then remove the soldering iron.
-
Continue with the other connections the same way, taking special care not to solder two of the pads together.

To reassemble your device, follow these instructions in reverse order.

TIP: Another method which works well for clearing solder from holes (especially on repairs like AC Jacks on laptops) is to use compressed air to clear melted solder from holes. A quick blast with a duster can works well (I have even used a drink straw in a pinch and blown out with a blast of air from mouth). Heat the solder until it liquefies, put the duster straw right above the solder and quickly hit the melted solder with an air blast to instantly clear the hole of solder. This works well on very small holes as melted solder does not always push out cleanly with metal tools. You have to be quick with the air blast because the solder re-hardens rapidly.
This is not IPC standards but for the ghetto approach, it will get the job done. I solder in manufacture settings, run my own shop. This is wrong to a degree but will do. If ifixit would like tips from ILLFIXIT then your more then welcome!
A very good guide to soldering.
I have never soldered anything (I'm a girl you see), but your clear and detailed guidance inspired me to give it a go.
I was well prepared in advance-it could be difficult-and that helped a lot.
I have now got a new battery soldered into my Palm TX and I'm as happy as Larry (or Lorraine in this case)..
Go Gurl! I'm a gurl, too. I worked in my dad's machine shop for 13+ years. I hit the ground running. Programmed, set up, and fixtured, retro-fitted CNC Mills, using SurfCam and G Code programming. We used Master Cam for the wire EDM. My fave was running a standard lathe. I guess I enjoy cylindrical objects. We held tolerances of .005+/- .001, all the way down to .0003+/-.0002. That…is very microscopic. lol
…add to that, Public Relations, Inventory, Inspector, Fixing Crashed tools, Shipping, Document Control, and so on. All I know is, if it needs to be done, it can be done, if your sharp. And, sometimes we gurls, have a different “feel” for delicate or fine work, as compared to some of the guys. There is nothing we cannot do, as well as anyone else, if we want to, and are willing to learn, and practice. I'm ready to try a little delicate connecting, myself.
