What parts are on the mobile phone motherboard
Leave a message
The main board of mobile phone is mainly composed of three parts, namely radio frequency part, baseband part and other parts.
Base Band
The baseband chip and power management chip are responsible for coding.
RF part
RF processor and RF power amplifier are used to receive and transmit signals.
Other parts
Many parts of mobile phones are concentrated on each chip, including various controllers and hardware facilities of mobile phones, earphones, speakers, microphones, screen keyboard motherboards and various chips, including capacitors, resistors and batteries.
The mobile phone motherboard is the main circuit board in the mobile phone, known as the "printed" circuit board, which contains the main electronic components and interfaces, and some auxiliary electronic components. The main board uses insulating material as the base material, cuts into a certain size of plate according to the requirements, and performs holes according to the wiring requirements to realize the interconnection between electronic components; This kind of board is made by electronic printing technology.
The CPU on the main board of the mobile phone is used for signal processing with small current, so the pin of the CPU is usually not as thick as the power amplifier. So in many cases, the CPU on the board will be a very precise BGA (internal pin) chip, which will also be relatively large, and there are not many complicated things around.
mobile phone
Mobile phones, generally called mobile phones or wireless phones, are divided into smart phones and non-smart phones. Generally, the performance of smart phones is better than that of non-smart phones, but the performance of non-smart phones is more stable than that of smart phones. Most non-smart phones and smart phones use the CPU of ARM in the UK.
In terms of mobile phone appearance, the most commonly used classification is to divide the mobile phone into straight plate type, folding type (single screen, double screen), sliding cover type, rotary type, side sliding type, etc.
