PCB News - Precautions for PCB circuit board proofing

PCB circuit board proofing is to determine whether there is a problem with the manufactured circuit board and whether it can achieve the required functions before mass production. To avoid problems in the later stage, resulting in scrap and increasing costs, so PCB circuit board proofing is very important.

1. As a group of engineers, the precautions for PCB circuit board proofing are as follows:

1. It is necessary to select a reasonable number of samples according to different situations to reduce costs.

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

3. Conduct a comprehensive electrical inspection on the PCB circuit board to improve the electrical performance of the circuit board.

4. Do a good job in signal integrity layout, reduce noise, and improve the stability of the circuit board.

2. As a manufacturer, PCB proofing needs ideas:

1. Carefully check the relevant PCB files to avoid data problems.

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

3. Conduct in-depth communication with customers, understand customer requirements and precautions in detail, and prevent mistakes.

Three, the PCB circuit board proofing process, the matters needing attention are as follows:

1. Layout and routing of components

The layout and wiring of the components have a great impact on the life, stability, and electromagnetic compatibility of the product, so special attention should be paid. Need to pay attention to the placement order of the components, usually place the components in a fixed position related to the structure first, and place other components from large to small. In addition, the component layout needs to pay attention to the heat dissipation problem. The heating components should be distributed and not concentrated in one place.

2. Adjust and perfect

After the PCB circuit board wiring is completed, some adjustments to the text, individual components, wiring, and copper are needed for production, debugging, and maintenance.

3. Use simulation function for PCB circuit board proofing

In order to ensure that the PCB circuit board can be proofed correctly, software can be used for simulation. Especially for high-frequency digital circuits, some problems can be found in advance and the workload of later debugging can be reduced.

The above is the analysis of the precautions for PCB circuit board proofing. Ipcb also provides PCB manufacturers and PCB manufacturing technology.
