PCB Technical - It is not easy to make a PCB printed circuit board

PCB (Printed Circuit Board), the Chinese name is printed circuit board, also known as printed circuit board, printed circuit board. It is an important electronic component, a support for electronic components, and a provider of electrical connections for electronic components. Because it is made by electronic printing, it is called a "printed" circuit board. PCB copy board, that is, on the premise that there are already physical objects of electronic products and circuit boards, reverse analysis of the circuit boards by reverse research and development technology, and the original product PCB files, bill of materials (BOM) files, and schematic files Perform a 1:1 restoration of technical documents and PCB silk screen production documents, and then use these technical documents and production documents to perform PCB manufacturing, component welding, flying probe testing, circuit board debugging, and complete the complete copy of the original circuit board template.

PCB copy board, currently in the industry is often referred to as circuit board copy board, circuit board clone, circuit board copy, PCB clone, PCB reverse design or PCB reverse research and development. Regarding the definition of PCB copy board, how much does the industry and academia have This kind of argument, but they are not complete. If we want to give an accurate definition of PCB copy board, we can learn from the authoritative PCB copy board laboratory in China: PCB copy board, that is, there are physical objects of electronic products and circuit boards. Under the premise of, use reverse R&D technology to reversely analyze the circuit board, and restore the original product's PCB files, bill of materials (BOM) files, schematic files and other technical files and PCB silk screen production files at 1:1. Then use these technical documents and production documents for PCB manufacturing, component welding, flying probe testing, circuit board debugging, and complete the complete copy of the original circuit board template. Since electronic products are composed of various types of circuit boards, the core control part performs work. Therefore, the use of a process of PCB copying can complete the extraction of a full set of technical data of any electronic product, as well as the imitation and cloning of products.

Many people have misunderstood the concept of PCB copy board. In fact, with the continuous development and deepening of the copy board industry, today's PCB copy board concept has been extended to a wider range and is no longer limited to simple circuit board copying and cloning., It will also involve the secondary development of products and the research and development of new products. For example, through the analysis and discussion of existing product technical documents, design ideas, structural features, process technology, etc., it can provide feasibility analysis and competitive reference for the development and design of new products, and assist R&D and design units to follow up the latest updates in time Technological development trends, timely adjustment and improvement of product design plans, and research and development of the most competitive new products in the market. At the same time, the process of PCB copying can realize the rapid update, upgrade and secondary development of various types of electronic products through the extraction and partial modification of technical data files. Customers wish to optimize the design and board modification of the PCB, and on this basis, they can also add new functions to the product or redesign the functional features, so that products with new functions will be unveiled at the fastest speed and in a brand-new posture. Not only has its own intellectual property rights, but also won the first opportunity in the market, bringing double benefits to customers.

PCB copy board is to clone the circuit board, export the schematic diagram, etc. in the case of the existing PCB circuit board. It is a file used for production. On this basis, it can also carry out secondary development and redesign according to user needs to realize product function upgrade and expansion. So how to change from the schematic diagram of the PCB copy board file to the actual PCB board?

Perhaps everyone knows that to make a PCB board is to turn a designed/cloned schematic into a real PCB circuit board. Please don’t underestimate this process. There are many things that work in principle but are difficult in engineering. Realization, or something that others can achieve, others can't. Therefore, it is not difficult to make a PCB board, but it is not easy to make a PCB board well.
