Remove all devices and remove the tin from the PAD hole. A lot of pcb boards are getting higher and higher. It is best to take a photo of two component locations with a digital camera. Get a PCB, first record the model, parameters, and position of all electronic components on the paper, especially the direction of the diode, the three-stage tube, the direction of the IC gap. Request PCB Manufacturing & Assembly Quote Now PCB schematic reverse step process: 1. Then, according to the document map or the real thing, how to reverse the PCB schematic diagram, what is the reverse push process? What are the details of this attention? With the continuous development and deepening of the copy board industry, today’s PCB copy board concept has been extended to a wider range, no longer limited to simple board copying and cloning, but also involves secondary development of products and new products. Then use these technical documents and production documents for PCB board, circuit board soldering, flying probe test, PCBA debugging, complete the complete copy of the original circuit board template. That is, under the premise that there are physical objects and circuit boards, the reverse analysis technology is used to reversely analyze the circuit board, and the original product PCB file, bill of materials (BOM) file, schematic file and other technical documents and The PCB silk screen production file was restored 1:1.
