What preparations need to be done before PCB proofing?

Shenzhen  Viasion Electronics is a PCB manufacturer with more than ten years of PCB manufacturing experience. It specializes in PCB proofing, circuit board proofing, impedance board, HDI board, blind buried via board and other multilayer PCB board proofing and small batch production. Next, I will introduce what preparation work needs to be done before PCB proofing.

There are simple and complex PCB boards. Simple PCB boards need not be said to be easy to proof, but if it is a complex circuit board proofing, you must be cautious. If you don’t need to check the relevant inspection tools during the PCB proofing process, in case something goes wrong, It was too late until the PCB board was ready. Therefore, we must make full preparations before proofing.

Preparation before PCB proofing

 1. Making the physical frame

The closed physical frame is a basic platform for the future component layout and PCB proofing. It is necessary to pay attention to accuracy. Furthermore, it is best to use arcs at the corners, which can not only avoid scratches by sharp corners, but also reduce stress. .

2. Introduce components and networks, and lay out components

 When drawing components and networks into the frame of PCB proofing, you must carefully follow the prompts to operate, including component packaging and component network issues. Because of the contrast prompts, problems are not easy to occur. Layout components and traces have a great impact on product life, stability, and electromagnetic compatibility during PCB proofing, so special attention should be paid. Generally speaking, there should be the following principles: placing order and paying attention to heat dissipation.

3. PCB design wiring and adjustment

It is best to pay attention to the requirements of processing parameters when designing and wiring PCB, or to a reliable PCB proofing manufacturer, the defective rate will be greatly reduced. After completing the PCB design and wiring, all you need to do is to adjust the text, individual components, wiring and apply copper (this work should not be too early, otherwise it will affect the speed and bring troubles to the PCB design and wiring), the same is for It is convenient for production, debugging and maintenance.

 4. Check the network

Sometimes the network relationship of the PCB board drawn is different from the schematic diagram due to misoperation or negligence. At this time, inspection and verification are necessary. So after finishing painting, you should check it first, and then do follow-up work.
