| Pin Count | 2522 |
| Layer Number | 6 |
| Design Challenges | 1. PCBA signal stability. 2. Heat dissipation. |
Strategy:
1. The power section uses a wide range of GND grounding, isolating the signal layer from the power layer to avoid signal interference;
2. The IXTH24N50L chip group is designed independently, with added heat sinks to form isolated power.
