Mobile PCB are one of the most critical components inside a mobile phone, responsible for power and signal transmission as well as the connection and communication between different modules. The distribution of layers on the PCB is also very important, let's delve into the details now.
Typically, mobile PCB use a four-layer or six-layer design. The distribution of layers in a four-layer PCB is relatively simple, mainly divided into two layers, namely the top layer and the bottom layer. The top layer is where the main chips, signal lines, and keyboards are located, while the bottom layer is primarily for connecting modules such as the battery and power supply. Four-layer PCB were commonly used in early mobile phones but have almost been replaced by six-layer PCB today.
The distribution of layers in a six-layer PCB is relatively more complex. In addition to the top and bottom layers, there are four internal layers, which are mainly used to connect chips, transmit and receive signals, and display screens. The top and bottom layers mainly house connection signals, power supplies, and more important modules, as well as digital cameras, accessory interfaces, etc. The internal layers are primarily for placing electronic components such as processors, memory, and wireless network modules.
Furthermore, in the design of mobile PCB, professional designers from mobile phone manufacturers will formulate specific wiring and interconnection principles based on the distribution of layers to ensure that the communication between modules and the effectiveness of sending and receiving signals to the outside world are more excellent.
In summary, the distribution of layers on mobile PCB has a crucial impact on the signal transmission, operational efficiency, and power consumption of mobile phones. As mobile phones evolve, the structure and distribution patterns of electronic communication PCB are also continuously being optimized and improved.
