With the development of circuit board copy board technology, the application of these copy boards is more and more extensive, in the current intelligent digital field, it is because of these copy board technology is very superior, so that the performance of smart phones and tablet computers and other products has been a qualitative leap. In addition, in the military, aerospace and electric power and other fields, a series of pcb boards have been widely used. In life we use the apple cell phone and tablet computer is because of these line copy board technology support, with the continuous development of these design technology, copy board utilization will become more and more extensive.

　　The current circuit board copy board development team’s technology is getting rapid development, in the circuit board copy board design, these good transmission lines can also ensure the stable operation of the multilayer circuit board. China’s circuit board copy board technology has also been greatly improved, and greatly shorten the technical gap with the developed countries, and some products are also exported to foreign countries. China’s circuit board copy board development and research technology level is also more and more advanced, which also greatly promotes China’s digital technology and even the whole science and technology enhancement.
