1. When the hole is punched, you need to open the package geometry/silkscreen_top or bot. If you don't open the hole, if you don't open it like this, it's not easy to identify the inductance. You mistakenly used VIA to induct the inductance.

6. The area of ​​the metallized mounting hole has the risk of puncturing the PCB due to the burr of the structure itself. Therefore, it is recommended that the front 3 layers and the rear 3 layers of the PCB design be prohibited from being traced. The power supply prevents the structural components from being punctured to cause open short circuits. problem.
