Detailed explanation of circuit boards

I.Definitions and Basic Components

Circuit Board (PCBA) : A circuit board generally refers to a complete product in which electronic components have been mounted or inserted onto a circuit board through the SMT surface mount assembly process or the DIP through-hole assembly process. Therefore, the circuit board not only encompasses all the functions of the wiring board but also realizes the electrical connection between electronic components, and can be used as a complete functional module.

Ii. Functions and Usage

Circuit boards, on the basis of incorporating all the functions of circuit boards, achieve more complex circuit functions by mounting or plugging in electronic components. It can be an independent functional module, such as a power module, a signal processing module, etc. It can also be a combination of multiple modules to form a complete electronic system.

Iii. Structure and Manufacturing Process

The circuit board adds electronic components and solder joints, wires, etc. that connect these components. Its manufacturing process not only includes the production process of circuit boards, but also the steps of component mounting, soldering, testing, etc. The production of circuit boards requires high-precision equipment and strict process control to ensure the performance and reliability of the circuits.

Iv. Application Scenarios and Selection

Circuit boards are widely used in various electronic devices, especially those with high requirements for circuit performance and functions, such as mobile phones, computers, servers, etc. In high-end electronic devices and professional fields, such as aerospace and medical equipment, the complexity and precision of circuit boards are higher. In these application scenarios, circuit boards not only need to provide stable electrical connections and physical support, but also need to achieve complex circuit functions and system integration.
