PCB Tech - PCB copying skills and robot research and development

One, PCB circuit board copying skills are exquisite

As we all know, one of the necessary skills of PCB copy board electronic engineer is circuit design, which shows the importance of circuit design.

The related content of circuit design mainly includes two aspects: circuit schematic design and printed circuit board design. Generally speaking, there is a small shortcut to learning circuit design, which is to analyze classic designs. Classical design also has many applications. For example, mass production of electronic products is one of them, as well as displays. The analysis of a classic design generally has the following steps, which generally include tablet readings, reverse push schematics, simulation analysis (which can be excluded) and modify the design to suit your application. Among them, plate reading is a kind of learning, the first step is also a relatively important step. Board reading is a PCB board design that uses reverse technology for research. First of all, we introduce to you the method of PCB copying and the steps to be performed. PCB copy board can also be said to be clone, which belongs to the reverse engineering part of PCB design.

This requires removing all the components on the PCB circuit board, then scanning the empty board into a picture, and recovering it to the PCB drawing file through the board software processing. Any electronic product can be imitated or electronic through the PCB Copy board and reverse technology. Product clone. In the inventory production process, first we need to clearly mark the content and data related requirements. In fact, in the making of the list, seemingly simple things hide a lot of learning. First of all, we should make corresponding preparations. First get a PCB, and use a better camera to photograph the positions of the two gases. The effect of the photograph must be clear, otherwise it is impossible. Then we need to write down a series of models, parameters and positions on the paper, especially the diode, the direction of the three tubes and so on. Be sure to remember. The next step is to publish the record. Let's delete all devices from the beginning. It should be noted that we know the number of related equipment and parameters, each component is deleted, corresponding to its position number and double-sided tape, etc. pasted on the white paper. Remind you that in the process of splitting the board, you must be especially careful about the number of components arranged for each person, because a small detail may lead to the cancellation of the entire project and affect the effect of the final clone. The last step is component testing. First of all, we get the relevant data list from the disassembly personnel, and we can formally enter the BOM production process, that is, through various tests and analyses, all the components of the relevant parameters are converted into the system table process. This is when we need to use an advanced instrument called Bridge Tester. The tester is mainly used for impedance analysis of various components of the measuring instrument. It uses advanced comparison methods to measure the resistance, capacitance and inductance of the components.

Of course, different levels of bridge test equipment have different test results and accuracy. Generally speaking, the bridge tester is divided into many types according to different grades. The use of this instrument can not only ensure higher accuracy, but also improve the intensity and efficiency of the measurement. Therefore, the PCB circuit board is more complicated and requires certain skills.

2. PCB copy board helps domestic high-end robot research and development

Wang Tianyao, professor of Beijing University of Aeronautics and Astronautics and honorary director of the Robotics Research Institute, stated at the China Robot Industry Development Forum 2019 that the world's industrial robot industry has recently experienced a decline or negative production. According to the data released by the National Bureau of Statistics on March 14, China's cumulative growth rate of industrial robot production showed a negative growth for the first time from January to February 2019, and continued to grow slowly in the second half of 2018, with the production of 20041 units, a year-on-year decrease of 11%. In this regard, Zhao Jie, the leader of the demonstration expert group of the "13th Five-Year" national key R& d program "Intelligent Robot Key Special", put forward his own ideas at the conference. The domestic robot industry pays too much attention to price. Although production has grown rapidly in the past, there are few real high-end robot products. He said that in the face of active competition from foreign brands, simply winning by preferential treatment is not a good way, nor does it conform to economic laws. 2019 is the most critical year for the robotics industry, and it can be called the "China Robot Transformation Year". The first is the transition from virtual to real. From 2018 to 2019, capital investment in the field of robotics has been transferred to the field of physical robotics. Moreover, the shift from quantity to quality. In recent years, the robotics industry has entered the "big wave and sand period", and many closed and operating companies have emerged, and core technology companies can survive. Compared with the pursuit of quantity in previous years, robot companies should shift from the pursuit of "quantity" to the pursuit of "quality" and the development of core technologies in 2019. The second is the transition from general to special. He observed that at present, more and more companies are beginning to dig deeper into a certain market segment in this field. Sun PCB Copy Board Studio has long focused on the R&D and development of robotic product technology. According to customer needs, it completes related technical performance upgrades and provides customers with complete technical support and complete product solutions.
