PCB circuit board copy of the skills and methods of speaking

People in the industry are well aware that one of the necessary skills of electronic engineers for pcb copy board is circuit design, which shows the importance of circuit design. There are two main aspects of circuit design, namely the design of the circuit schematic and the design of the printed circuit version.

In the process of creating the list, we need to clarify the contents of the label and the relevant data required. In fact, in the list making, a seemingly simple thing but there are a lot of hidden learning. First of all, we need to do the corresponding preparatory work. First get a piece of PCB, with a better camera to take two photos of the location of the meta-part, the effect of the shot must be clear, or not. Then we need to write down on paper all the components of a series of models, parameters, and location, especially the diode, the direction of the three machine tubes, etc. must be remembered especially clearly. The next step is to disassemble the version of the record. We first remove all the devices one by one.

It is important to note that after our knowledge also to several relevant devices and parameters, each component is removed, corresponding to its location number with double-sided tape or the like to paste it on white paper. To remind you is that in the process of splitting the board, the numbering of components must be arranged with special care, because a small detail may lead to the whole project before it is abandoned, affecting the final cloning effect. The last step to be carried out is the component test. First of all, we get the relevant data list from the hands of the demolition of the board, you can formally enter the BOM single production process, that is, through a variety of tests and analysis, all the relevant parameters of the components into a system of tables of the process. This time we need to use an advanced instrument, this instrument is called bridge tester. This tester is mainly for the impedance analysis of various components a measurement instrument, it uses the advanced comparison method to measure the resistance, capacitance and inductance of components. Of course, different levels of bridge test equipment with different test results and accuracy.

Generally speaking, there is a small shortcut to learning circuit design, which is to analyze the classical design. There are many applications of classical designs, such as mass-produced electronic products is one of them, and displays are also. Analysis of classic design generally has the following steps, which generally include copy board, reverse schematic, simulation analysis (this can be excluded) and modify the design to suit your application. Among them, the copy board is a kind of learning, the first step, but also a relatively important step. Copying is the study of the designed PCB board using reverse technology. We will first introduce you to the PCB copy method and the steps to follow. PCB copy can also be described as cloning, which is the reverse engineering part of PCB design. This requires the PCB circuit board components are removed, and then the empty board will be scanned into a picture by the copy board software processing to restore the pcb board diagram file, through the PCB copy board and reverse technology can be any electronic product imitation or electronic product cloning.

Generally speaking, the bridge tester is divided into many kinds according to different levels, the use of this instrument can not only ensure a higher accuracy rate, but also improve the intensity and efficiency of the measurement. Therefore, PCB circuit board copy is more complex and requires certain skills.
