[0002] PCB, also known as printed circuit board, is the provider of electrical connections for electronic components. It has a history of more than 100 years; its design is mainly layout design; the main advantage of using circuit boards is that it greatly reduces wiring and assembly errors, improves the level of automation and production labor rate. A large number of electronic components will be installed on the PCB, so as the PCB works, the electronic components will generate a lot of heat, and the highly integrated circuit structure on the PCB will have a great impact on heat dissipation.
