Many people have misunderstandings about the concept of PCB copy plate. In fact, with the continuous development and deepening of the copy of the board industry, today’s PCB copy concept has been extended widely, and it is no longer limited to the copy and cloning of simple circuit boards and cloning. It will also involve the second development of the product and the development of new products. For example, through the analysis of existing product technical documents, design ideas, structural characteristics, process technology, etc., you can provide feasibility analysis and competitive reference for the research and development and design of new products, and assist R & D design units to follow up the latest. The technological development trend, timely adjust the improvement of product design plans, and develop the most competitive new products in the market. At the same time, the process of PCB copy plate through the extraction and partial modification of the technical data files can realize the rapid updates and upgrading of various types of electronic products. According to the file diagram and schematic diagram extracted by the copied board, professional designers can also be based on Customers' willingness to optimize the design and modification of the PCB, and can also add new functions to the product or redesign the product on this basis. Not only has its own intellectual property rights, but also won the opportunity in the market, bringing dual benefits to customers.
