10-layer 3-connector motherboard


This is a 10-layer, three‑stage mobile phone motherboard—also known as a smartphone PCB—which belongs to the category of high‑density HDI multilayer boards. It integrates the application processor, baseband communication, RF circuitry, power management, and storage circuits, serving as the core platform for the device. In contrast to the preceding examples: laptop motherboards prioritize computing performance; communication boards focus on network transmission; whereas mobile phone motherboards achieve a highly integrated design that combines computing power with RF communication, while maximizing space efficiency.
