The PCB copy is a category of reverse engineering. Since the birth of the entire concept, it has been under extensive controversy. The method of reverse engineering has played a huge role in the development of the integrated circuit industry. Methods to understand the development of other people's products. If this behavior is strictly prohibited, it will affect the advancement of integrated circuit technology. Therefore, countries will be regarded as an exception of infringement under certain conditions when legislative. In order to teach, analyze and evaluate the concepts, technology, or the circuit, logical structure, and component configuration used in the design of the cloth design, copy the cloth design and apply the analysis and evaluation results to the original cloth map on this basis In the design, the integrated circuit is made based on this, which is not regarded as infringement. However, it should be considered as infringement, which simply replicate the protection of the protection of others for business and sales.

　　In January 2007, the Supreme People's Court of China announced "an interpretation of several issues on the application of laws on the application of improper competition for civil cases", which stipulates that the business secrets obtained by self -development and development or reverse engineering are required. Instead of business secrets stipulated in the clause.

　　The judicial interpretation also stipulates that reverse engineering refers to the technical information of the product obtained by disassembling, surveying and mapping, and analysis of products obtained from open channels through technical means. After the parties knew the business secrets of others in improper means, those who had to obtain the behavior on the grounds of reverse engineering were not supported.

　　The judicial interpretation was officially implemented from February 1, 2007.

　　Many formal copy -on -board unit institutions have clearly stipulated that all customers who carry out reverse projects in the company must have a legitimate design copyright source statement to protect the legitimate rights and interests of the original design copyright owner, and request customers to promise to reverse the reverse. The results are mainly used for legal uses such as teaching, analysis, and technical research. At the same time, reverse engineering is committed to carrying out secondary development in the original product design ideas, analyzing and data extraction through circuit principles, adding new design concepts and functional modules to product design, and quickly realizing innovation upgrades and updates on the original product basis Instead, it helps improve the overall competitiveness of the e -industry.
