product details：
PC board "is an abbreviation that usually refers to a printed circuit board (PCB). PCB is a substrate used to support and connect electronic components, whose main function is to provide connections and circuit layout between electronic components. There is a layer of insulation substrate on the PCB, which is covered with conductive tracks, which are used to conduct current and signals, thus achieving the functions of electronic devices.
PCB is widely used in various electronic devices, including computers, mobile phones, televisions, automotive electronics, medical equipment, communication equipment, etc. Here are some key information about PCBs:
Construction and composition: A PCB usually consists of an insulating substrate, a conductive layer (usually copper), a printed circuit, and connection points. The printed circuit on the conductive layer connects various electronic components, while the connection points are used to connect external power sources and other devices.
Conductive tracks: The conductive tracks on a PCB are made by chemical corrosion, etching, or other processing methods, forming circuits and allowing current and signals to flow between components.
Component installation: Electronic components (such as integrated circuits, resistors, capacitors, connectors, etc.) are installed on a PCB by welding or inserting to perform specific circuit functions.
Hierarchy: A PCB can be a single panel, double-sided board, or multi-layer board, depending on the complexity and functionality of the circuit. Multilayer boards can accommodate more circuit connections and are typically used in high-performance electronic devices.
Application field: PCB has been applied in various electronic devices, from small consumer electronics products to large-scale industrial control systems, using different types of PCBs.
Signal transmission: PCB is used to transmit digital and analog signals, which can perform various functions in electronic devices, such as data processing, control operations, etc.
Power distribution: The wire network on the PCB is used to distribute power to provide the required electrical energy to various electronic components, including providing power at different voltage and current levels.
Mechanical support: The PCB provides a sturdy structure to support and protect electronic components and ensure their correct installation in the device.
