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 board reading, that is to say, on the premise of existing electronic products and circuit boards, reverse analysis of circuit boards is carried out by means of reverse R&D technology. The original PCB documents, BOM documents, schematic documents and PCB silk printing production documents are restored by 1:1, and then these documents are used. Technical documents and production documents are used for PCB board making, component welding, flying needle testing, PCB debugging, and complete the complete replication of the original PCB template.
PCB抄板概念最初诞生于反向工程在国内学术界开始兴起的二十世纪八十年代，是由当时国内最初组建的反向工程技术研究 团队龙人PCB工作室提出的全新概念，历经将近30年的发展，目前，PCB抄板已经成为一个服务于全球电子产业发展和国内核心技术研究的全球性行业，国内 外各类抄板公司也已经遍地开花。近年来，这个行业的发展以及其在科技领域引发的种种轰动，使越来越多的人开始关注它，也使更多的企业通过他们的服务而走进 了在科技上敢与国际大企业抗衡的时代。特别是在中国江浙和广东一带，PCB抄板较为盛行，而且还出现了一批专门从事PCB抄板技术研究的权威实验室，如龙 人PCB工作室、世纪芯科技、芯谷等等。
The concept of PCB board-copying was originally born in the 1980s when reverse engineering began to rise in the domestic academic circles. It was a brand-new concept put forward by the Dragon PCB studio, a reverse engineering research team initially set up in China at that time. After nearly 30 years of development, PCB board-copying has become a service for global electronics. In the global industry of industry development and domestic core technology research, various kinds of board-copying companies at home and abroad have also been blooming everywhere. In recent years, the development of this industry and all kinds of sensations in the field of science and technology have made more and more people begin to pay attention to it, and also made more enterprises enter the era of competing with international large enterprises in science and technology through their services. Particularly in Jiangsu, Zhejiang and Guangdong provinces of China, PCB sheeting is more prevalent, and a number of authoritative laboratories specializing in PCB sheeting technology research have emerged, such as Longren PCB studio, Century Core Technology, Core Valley and so on.
