X-ray inspection reveals the internal structures of both devices without the need for disassembly.
Wireless charging operates without physical connections, utilizing electromagnetic induction through coils. When current flows through the transmission coil in the charger, it generates a magnetic field. Placing a smartphone within this field induces current in the phone's receiving coil, transferring electrical power for charging. The X-ray image allows for the verification of coil alignment and winding conditions.
The high-resolution X-ray image captures minute details of the smartphone's internal assembly. Key components such as the camera lens, antenna, display connections, and BGA ICs are clearly visible, along with the precise layout of PCB vias and wiring patterns.
