Company introduction

iPCB Circuits Limited(iPCB®) is a high-tech enterprise focus on the R&D and production of precision PCB prototype. iPCB independently developed the first PCB Automatic Quotation System(PAQS) in the industry, which automatically connected our PCB factory to realize intelligent service and PCB prototype rapid fabrication. Our ultimate goal is to build an Internet + industry 4.0 intelligent PCB factory cluster to provide professional PCB technology and PCB prototype fabrication services for customers.

iPCB® manufactures microwave radio frequency(RF) PCB, hybrid high frequency PCB, (1-70layers) multilayer PCB, HDI PCB, rigid-flex PCB, metal based PCB, ceramic PCB. We have deep research on PCB with special requirements such as blind buried hole PCB, back drilling PCB, step slot PCB, IC carrier PCB, ultra thick copper PCB, etc

What does the mobile phone motherboard look like? The mobile phone motherboard is the main circuit board in the mobile phone. There are three main parts on the mobile phone motherboard: baseband chip and power management chip: responsible for coding; RF processor and RF power amplifier: responsible for transmitting and receiving signals; Other CPU memory controller, touch screen, Bluetooth WiFi sensor, etc.

There are also some microphones, headphones, speakers, cameras, screens, interfaces, etc. These things are welded on a circuit board, which is called the mobile phone motherboard. Mobile phone motherboard function: integrate mobile phone operation management.

Extension: there is also a flat cable coexisting with the mobile phone motherboard. Flat cable is something that can see orange light transmission and black line at the bottom of the screen when the mobile phone is turned on. Causes of mobile phone motherboard failure: the first major cause of mobile phone motherboard failure is liquid intrusion: including mobile phone falling into water and accidentally falling into other liquids;

Use mobile phones in extreme environments; Electrostatic breakdown of main board components; Accidental fall; The transient current of the main board increases, which is mainly caused by battery short circuit and other faults; Use a mismatched charger.
