The design of printed circuit board is based on the electronic circuit diagram to realize the function that the circuit user needs. The design of printed circuit board mainly refers to the layout design. It needs the layout of the internal electronic components, metal wires, through holes and external connections, electromagnetic protection, thermal dissipation, crosstalk and other factors. Excellent circuit design can save production cost and achieve good circuit performance and heat dissipation performance. Simple layout design can be done by hand, but complex circuit design usually needs to be aided by computer aided design (CAD), and the well-known design software includes Protel, OrCAD, PowerPCB, FreePCB and so on.
