Key Points and Standards for Power PCB Design (Systematic Compilation)
1. Power Connector Design Standards Electrical Clearance and Creepage Distance The electrical clearance between the power and protective ground (PGND) should be ≥2mm, and the creepage distance should be ≥2mm (before the fuse) or ≥1.4mm (after the fuse). The distance between PGND and other signals (such as GND, low-speed signals) should be ≥2mm, and the … Read more
