Use altium designer to draw your own integrated library. When updating the PCB, it is found that footprint not found appears
I searched for a lot of methods on the Internet and they didn't work. Later, I occasionally saw a friend remind me to move the order of my integrated library to the top. It can be effectively solved.
Enter the library management interface of altium designer, select your own integrated library, and then click to move up, all the way to the top. Update the schematic to the PCB again and find that it has been successful. This problem can be solved.
