One improvement method is to closely inspect the film line during the PCB production process to ensure it is not scratched or damaged. Additionally, maintaining a clean environment and regularly cleaning the coated screen can prevent garbage from causing short circuits. Moreover, ensuring that the anti-plating layer is properly fixed and covers all exposed copper can help prevent short circuits from occurring. Regular maintenance and inspection of the PCB production equipment can also help identify and address any potential issues before they lead to short circuits.
