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.
