The design of the printed circuit board is based on the circuit schematic diagram to realize the functions required by the circuit designer. The design of the printed circuit board mainly refers to the layout design, and the layout of the external connection needs to be considered. Optimized layout of internal electronic components. Optimized layout of metal wiring and vias. Electromagnetic protection. Various factors such as heat dissipation. Excellent layout design can save production costs and achieve good circuit performance and heat dissipation performance. Simple layout design can be implemented manually, and complex layout design needs to be implemented with the aid of computer aided design (CAD).
