Circuit Design Of Printed Circuit Board

The design of the printed circuit board is based on the electronic circuit diagram to realize the functions required by the circuit user. The design of the printed circuit board mainly refers to the layout design, which requires various factors such as the layout of internal electronic components, metal connections, through holes and external connections, electromagnetic protection, heat dissipation, and crosstalk. Excellent circuit design can save production costs and achieve good circuit performance and heat dissipation performance. Simple layout design can be realized by hand, but complex circuit design generally needs to be realized with computer-aided design (CAD), and well-known design software includes Protel, OrCAD, PowerPCB, FreePCB, etc.
