iPhone 17 Air IC Diagram Motherboard Schematics

iPhone 17 Air IC Diagram The iPhone 17 Air’s motherboard schematics reveal a highly compact and optimized layout, showcasing Apple’s continued focus on performance, thermal efficiency

and modular repairability. At the heart of the board lies the A19 Pro SoC (System on Chip), which integrates CPU, GPU, and AI processing units for faster on-device computing. Surrounding the central chip are carefully positioned ICs (integrated circuits) including the NAND flash for storage, RAM modules, and logic EEPROM for secure boot and hardware identification.

Post Index:Power distribution is handled by a redesigned Power Management Unit (PMU), which now includes more efficient voltage regulation for the display, processor, and wireless modules. A dedicated Camera Power IC supplies precise voltages for the device’s multi-lens camera system, including 3.2V and 6.0V rails for autofocus and optical image stabilization. The Face ID system is powered by its own PMIC, ensuring isolated and secure operation.

Communication chips for Wi-Fi, Bluetooth, GPS, and NFC are grouped into a dedicated wireless module, while a separate Baseband processor manages cellular connectivity, supported by signal amplifiers (PAs), WTR transceivers, and coupling components to maintain high-speed data transmission. Notably, the inclusion of an updated USB-C management IC and charging controller reflects Apple’s shift to universal charging standards.

The schematics also illustrate modular connector zones—such as the battery, SIM, display, and camera—designed for easier disassembly and replacement. This modularity, combined with identity resistors that allow for part cross-compatibility between similar models, positions the iPhone 17 Air as one of the most serviceable iPhones yet, without sacrificing its high-end performance and sleek design.

iPhone 17 Air IC Diagram The image provided is a labeled component diagram of the iPhone 17 Air motherboard (also known as the mainboard), displaying a detailed breakdown of its key hardware chips and connectors in both Chinese and English. Among the marked components are the A19 Pro CPU (main processor), NAND storage, logic EEPROM, power management unit (PMU), battery and SIM card connectors, charging IC, and display/touch connectors. Other critical elements include the camera supply IC (3.2V/6.0V for autofocus), USB management IC, Face ID PMIC, audio chips (both small and large), and a variety of wireless communication modules such as GPS, Wi-Fi, Bluetooth, and NFC.

Also shown are essential components like the performance IC, baseband chip for cellular communication, wireless charging connector, flash LED controller, Wi-Fi/Bluetooth signal couplers, secondary PMU, BB EEPROM, and various power amplifiers and signal ICs (e.g., ROSE, PA, WTR).

This diagram is extremely valuable for technicians. It acts as a roadmap when diagnosing and repairing smartphones. For example, if a camera isn’t functioning, the technician can immediately locate and test the camera PMIC and related power supply lines. If the phone won’t charge, attention is directed to the charging IC and battery connector.

Additionally, while there may be slight differences between motherboards in models like the iPhone 17 Air and iPhone 17 Pro Max, the diagram also notes that identity resistors can be adjusted to make certain components universally compatible. This is particularly useful in repair work, as it enables parts from similar models to be interchanged, streamlining the repair process and reducing the need for exact model replacements.

What’s New on the iPhone 17 Air?

iPhone 17 Air IC Diagram The iPhone 17 Air introduces several key hardware innovations aimed at improving performance, efficiency, and repairability.

Revised Motherboard Layout:

iPhone 17 Air IC Diagram One of the most notable changes is the shift to a horizontal logic board positioned at the top of the device. This new layout allows for more internal space, enabling Apple to increase battery capacity—resulting in improved battery life. Additionally, a new steel battery casing combined with a vapor chamber for heat dissipation helps keep the device cool during use. This reduces the risk of heat-related damage and enhances overall reliability, especially when the phone is in direct contact with the user.

Easier Repairs:

iPhone 17 Air IC Diagram Apple has continued its push toward more repair-friendly designs. The updated internal connections make components like the battery easier to detach and replace, significantly simplifying repair procedures for technicians. A particularly innovative feature is the introduction of an electrically induced battery removal system, which minimizes the risk of damage during battery extraction and replacement.
