Computer Circuit Board means that the PCB/PCBA is applied to the computer.
Characteristics:
1. Densification: The high density of PCB can be developed with the improvement of IC integration and installation technology.
2. High reliability (Hi-Rel): Through a series of inspections, tests and aging tests.
3. Designability: Can be achieved through standardization and standardization of design, with short time and high efficiency.
4. Productibility: Adopting modern management, can carry out standardization, scale (quantity) change, automation and so on production, guarantee product quality consistency.
5. Testability: A complete test method is established to test all kinds of test equipment and instruments to test and identify the PCB product's qualification.
6. Composability: Not only facilitate the standardized assembly of various components, but also enable the automatic large-scale production.
7. Maintainability: As PCB products and various components are standardized design and mass production, therefore, in case of system failure, the system can be replaced quickly.
What is a Computer Circuit Board?
The Computer Circuit Board is one of the core components in a computer. It is equivalent to the skeleton or trunk of a computer, used to support the connection of various hardware. All the hardware in the computer must be installed and connected to the Computer Circuit Board, so the Computer Circuit Board can also be called the Computer Circuit Board. Some of the hardware mentioned above, such as CPU, memory, hard disk, graphics card, network card, sound card, etc., must be installed on the Computer Circuit Board so that these hardware can work normally and cooperate with each other.
The composition of the Computer Circuit Board
The Computer Circuit Board is actually a large rectangular circuit board (PCB board). There are generally BIOS chips, BIOS batteries, I/O control chips, various interfaces, indicator light connectors, expansion slots and other components on the Computer Circuit Board.
The role of the Computer Circuit Board
Provide a platform for the combination of various hardware, just like an aircraft carrier can carry various fighters and provide a platform for fighters. The combined Computer Circuit Board system is a computer host. As long as peripherals such as monitors, keyboards, mice, etc. are added, it is a complete computer, also known as a PC.

A computer circuit board, also known as a motherboard or mainboard, is the main printed circuit board (PCB) in a computer system. They act as central hubs, connecting the various components within the computer and facilitating communication between them.
Key functions and features of computer circuit boards include:
Mainboard structure:
Motherboards typically follow industry-standard form factors, such as ATX, micro-ATX, or mini-ITX, which define the motherboard's physical size and layout.
They provide slots and receptacles for connecting the central processing unit (CPU), memory modules (RAM), expansion cards (such as graphics cards, network cards), and other peripherals.
Chipsets and buses:
The motherboard contains a chipset, which is a set of integrated circuits that manage communication between the CPU, memory, and other system components.
They provide various bus interfaces, such as PCI, PCI Express, and SATA, to connect and transfer data between different components.
Power transmission and management:
The motherboard includes the power connector and circuitry used to distribute power to the CPU, RAM and other components.
They may also contain power management features such as voltage regulation and thermal monitoring to ensure stable and efficient power delivery.
I/O port:
The motherboard provides a variety of input/output (I/O) interfaces, such as USB ports, audio connectors, Ethernet ports, and display outputs, to support the connection of external devices and peripherals.
BIOS & Firmware:
The motherboard usually includes Basic Input/Output System (BIOS) or Unified Extensible Firmware Interface (UEFI) firmware, which is responsible for initial system boot and configuration.
BIOS/UEFI firmware allows the user to access and configure various hardware settings such as boot sequence, overclocking, and system diagnostics.
Extended functions:
Motherboards often have expansion slots, such as PCI, PCI Express, and M.2 slots, allowing users to install additional hardware components such as graphics cards, network cards, and solid-state drives (SSDs).
Cooling & Thermal Management:
Motherboards may include heat sinks, fan headers, or integrated cooling solutions to manage cooling of the CPU and other heat-generating components.
Computer circuit boards are the foundation of desktop, laptop, and server computers and enable the integration and coordination of various hardware components to provide computing capabilities. Motherboard designs and features have evolved over time, keeping pace with advances in CPU, memory, and storage technology.
