The Chinese name of PCB is printed circuit board, also known as printed circuit board, printed circuit board, which is an important electronic component. As a support for electronic components, it provides electrical connections for electronic components. Because it is made by electronic printing, it is called a "printed" circuit board. PCB proofing refers to the trial production of printed circuit boards before mass production. Generally, electronic products are sent to the pcb manufacturer to be processed into pcb boards after the engineer's pcb layout design is completed. The update iteration of electronic products is relatively fast, so the demand for pcb proofing is gradually growing, and the market share is constantly expanding. As the technological requirements of electronic products are getting higher and higher, the information is getting faster and faster, leading to multi-layer pcb proofing The rise is relatively fast.

　　PCB proofing precautions

　　As a group of engineers, the precautions for PCB proofing are as follows:

　　 1. Choose the number of proofs carefully to effectively control the cost.

　　2. Specially confirm the device packaging to avoid proofing failure due to packaging errors.

　　3. Conduct electrical inspections to improve the electrical performance of the PCB board.

　　4. Do a good job of signal integrity layout, reduce noise and improve PCB stability.

　　As a PCB proofing manufacturer, the precautions for proofing are as follows:

　　 1. Check the PCB documentation carefully to avoid data problems.

　　2. Perform process approval and process configuration with its own manufacturers.

　　3. Control the production quantity, reduce costs and maintain quality.

　　4. Communicate precautions with proofing customers to prevent accidents in advance.
