What should be paid attention to when PCB copying and polishing?
There are many precautions for PCB copying, and if you don't pay attention, your efforts will be lost. Customers and companies who do PCB copying have some things to pay attention to.
Note for PCB copy board:
1. Before copying the board, it is a serialized work. The previous process is not handled well, which directly affects the success or failure of the subsequent project.
2. The customer is doing the PCB copy board while requesting the component BOM. The component settings of the PCB file should be carried out according to the standard, otherwise the preparation of the BOM list is prone to errors.
3. Be sure to pay attention to the polarity and direction of the components when disassembling the board. If you don't remember it, it is likely to make a mistake when you restore the board to make a prototype.
4. Pay attention to the size of the original PCB board. Due to the pros and cons of the scanner, the scanned board image will be different from the actual board size. Keep the picture the same as the actual board. Otherwise, the result will be the board, the components cannot be installed, and the file invalid.
5. Scan the picture to be clear, adjust the resolution of the scanner to a relatively high level, it is convenient to zoom in and view the details of the PCB board.
The PCB that needs to be copied must be intact and undamaged. If it is damaged, it may be impossible to copy or greatly increase the difficulty of copying; provide your own PCB copy requirements in detail, and do not need to make a BOM list and prototype.
If it is convenient, please try to provide more information about the PCB board to be copied, so that the company can shorten the copying time and ensure the success rate of copying. When sending the original board, the packaging is tight to prevent damage. ONESEINE TECHNOLOGY CO.,LTD was founded in 2003. It is a company dedicated to PCB proofing and mass production. It uses high-precision single-sided/double-sided/multi-layer circuit boards (1-26 layers), thermoelectric separation of copper substrates, and multilayer industrial control circuits. PCB, power supply pcb board, medical circuit board, security PCB board, communication PCB board, automotive circuit board, instrument circuit board, military circuit board, composite busbar copper substrate, foldable metal substrate, FPC soft and hard board, etc., quality A high-tech enterprise that guarantees, punctual delivery, and sales.
Pay attention to the PCB copy board when grinding the board:
a. Scan the backup grinding board pictures in time. For more complicated board grinding boards, there may be emergencies, such as mobile phone boards with blind and buried holes. The board is very thin, and the board is worn out if you do not pay attention to it. Without remedial measures, it was done in vain. You can scan several times to save the backup pictures, so you can be prepared.
b. The insulation layer of the board is very thin. Choose the material of the sanding board, master the strength, and be careful when grinding the board. The extremely professional things are involved here, so I will not go into details. If you have friends in the same industry Or if you are interested in this industry, welcome to discuss it together or in person.
c. There must be reasons why some PCB files cannot be added to the network, such as inaccurate packaging of components or incorrect or non-standard components. Special emphasis is given to the fact that there are many ways to copy the board. It is necessary to understand that a scientific process is produced in this way Yes, the diversification of methods --- rationalization --- standardization - finally to institutionalization, the importance of standardization to the success rate of a board need not be said.
Common problems of improper copy board:
1. Compared with the original PCB board, the PCB drawing may be smaller.
2. The document made does not match the original board.
3. PCB file cannot add network, etc.
4. After the grinding plate is worn out, there is no way to remedy the failure of the copying process. Perhaps most people are familiar with it. If the PCB copying work is carried out step by step according to the copying process, the chance of error will be relatively reduced. What I want to say is that copying the board is a part of the production process of a product, and the quality of the work before and after has a great influence on it, especially the complicated board column. The above is part of the narration of an old engineer of Keyou. The precautions are far more than these. Welcome to communicate with friends in the same industry and let customers understand that our company has a high copy board quality. This is due to the accumulation of technology, freezing three feet is not a day's cold, the source of the technical strength of Keyou comes from experience accumulation and continuous innovation, which is one of the reasons why our customers trust us!
