Logic Board
The main circuit board — the brain of your iPhone
The logic board is the main circuit board inside the iPhone. It houses the Apple A-series CPU, RAM, storage chips, Power IC, Touch IC, and all core components. Damage to the logic board is the most serious category of iPhone repair. However, chip-level microsoldering can often repair individual failed components without replacing the entire board — preserving data and saving significant cost.
Why It Matters For Your Repair
If a repair shop tells you your iPhone needs a new logic board, always get a chip-level second opinion first. Most logic board failures involve a single chip — Power IC, Touch IC, or a storage controller — not the entire board. A microsoldering technician can often fix this for a fraction of the cost of a full board replacement, with your data intact throughout.
