Introduction
Newer generations of iPhone, iPod nano, and iPod touch have batteries that are soldered directly to the logic board. This makes replacing the battery a much harder feat than other iPod and iPhone 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.
Parts
No parts specified.

-
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.

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.
