There are several ways to improve the anti-interference ability of a printed circuit board (PCB). Here are some of the most common methods:
1. Increase the thickness of the PCB: The thicker the PCB, the better it will be able to resist interference from external sources.
2. Use a ground plane: A ground plane is a large area of metal that covers the entire PCB. This helps to reduce interference by providing a common reference point for all the signals on the board.
3. Shielding: Shielding is the use of metal to block interference from entering or leaving the PCB. This can be done by adding metal layers to the PCB or by using metal enclosures around the PCB.
4. Proper routing: Proper routing of signals on the PCB can help to reduce interference. This means keeping sensitive signals away from sources of interference and making sure that signals are not run near power lines or other high-frequency sources.
5. Using high-quality components: Using high-quality components that are designed to resist interference can also help to improve the anti-interference ability of a PCB.
