Detail specification
Clearance & Creepage
Creepage ≥8.0 mm, clearance ≥5.5 mm; dielectric withstand 3750 VAC/60 s.
Most Critical: User safety and compliance with CCC/CE/UL.
Most Challenging: Maintaining these distances while densely packing power and control circuits – often requires board slots or insulating barriers.
Heavy Copper & Thermal Rise
Power traces ≥3 oz (selective 6 oz); temperature rise ≤45°C at 40°C ambient under full load.
Most Critical: Ensuring ampacity and long-term reliability.
Most Challenging: Etching heavy copper with minimal side-etch, and soldering large pads without heat soak issues.
Impedance & Signal Integrity
CAN/RS485 diff: 120 Ω ±10%; single-ended: 50 Ω ±10%; board-wide deviation ≤5%.
Most Critical: Stable communication with BMS and vehicle controllers.
Most Challenging: Compensating for dielectric constant drift (due to moisture/temperature) and the influence of thick copper on impedance.
