PCB, also known as printed circuit board, is the core component of almost every electronic product. As a crucial platform in electronic devices, PCB plays a crucial role in carrying out the connection and interaction of electronic components.

A typical PCB consists of several layers, each of which may contain a certain part of the circuit. Through precise layout and design, the conductive path on the PCB can efficiently transmit current while ensuring the stable operation of electronic devices. The design and manufacturing quality of PCBs directly affect the overall performance and reliability of electronic devices.

With the development of technology, PCBs are also constantly evolving. More advanced PCBs, such as high-frequency, high-speed, and high-density PCBs, are widely used in fields such as smartphones, medical devices, and aerospace to meet the growing demand for miniaturization and functional diversification of electronic devices.
