Concept of pcb board reading and detailed explanation of components

PCB (printed circuit board), also known as printed circuit board and printed circuit board in Chinese, is an important electronic component, the support of electronic components, and the provider of electrical connection of electronic components. Because it is made by electronic printing, it is called "printed" circuit board. PCB copy, that is, on the premise of having electronic products and circuit boards in kind, reverse analysis of circuit boards is carried out by means of reverse research and development technology, and 1:1 restore of PCB documents, bill of materials (BOM) documents, schematic documents and other technical documents of the original products as well as PCB silk printing production documents, and then use these technical documents and production documents for PCB making, component welding, flying pin testing, and circuit board debugging, Complete the complete copy of the original circuit board template.

Component introduction

PCB copying is also often referred to in the industry as circuit board copying, circuit board cloning, circuit board copying, PCB cloning, PCB reverse design or PCB reverse research and development. There are many opinions about the definition of PCB copying in the industry and academia, but none of them is complete. If you want to give a precise definition of PCB copying, you can learn from the statement of the domestic authoritative PCB copying laboratory: PCB copying, That is to say, on the premise that there are real electronic products and real circuit boards, reverse analysis of circuit boards is carried out by means of reverse research and development technology, and 1:1 restoration of PCB documents, bill of materials (BOM) documents, schematic diagram documents and other technical documents of the original products as well as PCB silk printing production documents is carried out. Then, these technical documents and production documents are used for PCB manufacturing, component welding, flying pin testing, and circuit board debugging, Complete the complete copy of the original circuit board template. As electronic products are all composed of various kinds of circuit boards, the core control part works. Therefore, the extraction of full set of technical data of any electronic product and the imitation and cloning of products can be completed by using such a process as PCB copying.

Many people don't know what PCB copy is. Some people even think that PCB copy is a copycat. In our understanding, copycat means imitation, but PCB copying is definitely not imitation. The purpose of PCB copying is to learn the latest foreign electronic circuit design technology, and then absorb excellent design schemes to develop and design better products.

PCB copy is a reverse research technology, which is to obtain a PCB design circuit of an excellent electronic product, as well as circuit schematic and BOM through a series of reverse research technologies. Through this reverse research method, it takes others two or three years to develop a product. Through the reverse research method of PCB copying, it may take us only one month to learn what others have developed in two or three years. This has played a very important role in promoting our developing countries to catch up with the world. Moreover, the development of reverse research technology also promotes the technical breakthrough of those development teams. The vigorous development of reverse research technology also leads to the continuous updating of positive research technology. Because of this competitive relationship between forward research and reverse research, the development of electronic technology has changed with each passing day in recent years. Electronic products are updated almost once a year, and the speed of updating electronic products will only become faster and faster. Because PCB reading lowers the threshold of electronic technology. PCB copying has enabled more and more developing countries to step onto the forefront of high and new electronic technology and research electronic technology together with developed countries. The larger the research team, the more electronic technology in the world can develop.

PCB manufacturers, PCB designers and PCBA manufacturers will explain the concept and components of PCB board copying.
