Preparations are required before PCB proofing
1. Make the physical frame The closed physical frame is a basic platform for future component layout and PCB proofing. Be sure to pay attention to accuracy. Furthermore, it is best to use arcs at the corners, which can not only avoid being scratched by sharp corners, but also Can reduce stress.
2. Introduce components and networks, and lay out components. When introducing components and networks into the drawn frame during PCB proofing, you must carefully follow the prompts, including component packaging forms and component network issues. Because of the comparison prompts, problems are not easy to occur. Layout components and routing have a great impact on product life, stability, and electromagnetic compatibility during PCB proofing, which should be paid special attention to. Generally speaking, there should be the following principles: placement order, attention to heat dissipation.
3. PCB design and layout and adjustment and perfection When designing and wiring the PCB, it is best to pay attention to the requirements of processing parameters, or go to a reliable PCB proofing manufacturer, and the defective rate will be greatly reduced. After completing the PCB design and wiring, all you need to do is to make some adjustments to the text, individual components, and wiring, and to apply copper (this work should not be done too early, otherwise it will affect the speed and bring trouble to the PCB design and wiring). It is convenient for production, debugging and maintenance.
4. Check and check the network Sometimes due to misoperation or negligence, the network relationship of the drawn PCB board is different from the schematic diagram. At this time, it is necessary to check and check. Therefore, after the painting is finished, it should be checked first, and then follow-up work should be carried out.
