CodePudding user response:

Check to see if your digital tube packaging is wrong, look at the "8" is screen printing

CodePudding user response:

To view the encapsulation, first confirm that show all layers, and then look at whether to have 8, if not, then may be accidentally deleted, if you have, where view layer and then confirm whether to open the layer in the PCB,
