note:
When designing, we generally ensure that the ground pin is first, the path is short, and the filtering effect is good. Such as:

note

The peripheral small circuits of BGA are as neat and beautiful as possible. The holes and lines are unified. Such as:

BGA

The beautiful circuit board comes from every detail of you, so you can't miss any detail!
