1. Beginner drawing circuit board needs to master some basic knowledge. 2. First, you need to understand the basic knowledge of the circuit, including current, voltage, resistance and other concepts, as well as the basic circuit components and their symbolic representation. Secondly, it is necessary to learn the drawing methods and specifications of circuit diagrams, and understand how to use circuit diagrams for circuit design and analysis. It is also necessary to understand common electronic components and devices, such as resistors, capacitors, diodes, transistors, etc., as well as their characteristics and methods of use. In addition, understanding some basic circuit analysis methods and tools, such as Ohm's law, Kirchhoff's law, oscilloscope, etc., helps to understand and solve problems in circuits. 3. After mastering the above basic knowledge, you can further learn more in-depth circuit design and layout skills, such as signal integrity, electromagnetic compatibility and other knowledge, in order to improve the performance and reliability of the circuit. At the same time, you can also learn the use of some circuit simulation software, such as Proteus, Altium Designer, etc., for circuit design and verification. In addition, understanding some common circuit board manufacturing processes and specifications, such as welding, printing, drilling, etc., helps in the operation and quality control of the actual production of the circuit board.
To draw a circuit board at the beginning, it is necessary to master the basic circuit principle and electronic component knowledge, understand the design process and production process of the circuit board, be familiar with the commonly used circuit board design software and production tools, and master the knowledge of the circuit board wiring rules and signal integrity.
In addition, it is necessary to have a certain mathematical and physical foundation, be able to understand the voltage, current, resistance and other concepts in the circuit, and master some basic calculation methods. Through continuous learning and practice, gradually improve their own circuit board design and production capabilities.
