product features of Rigid power inverters PCBs
1. High-Power Handling:
- Designed for high-voltage and high-current applications (up to 1000V, 50A+).
- Thick copper layers (2oz–6oz) to minimize resistive losses and ensure stable power transmission.
2. Robust Thermal Management:
- Aluminum-based or high-Tg FR-4 substrates with thermal conductivity up to 2.5 W/m·K.
- Integrated heat sinks and thermal vias for efficient heat dissipation in continuous operation.
3. Enhanced Durability:
- Resistant to high temperatures (operating range: -40°C to +150°C), humidity, and vibration.
- Reinforced mechanical strength for industrial and automotive environments.
4. Signal Integrity & EMI Control:
- Multi-layer designs (4–14 layers or customizable) with optimized grounding and shielding to reduce electromagnetic interference (EMI).
- Tight impedance control (±8%) for stable switching frequencies and noise suppression.
5. Customization:
- Flexible stack-up configurations for AC/DC conversion, DC/AC inversion, and hybrid topologies.
- Surface finishes: HASL (lead-free), ENIG, or immersion tin for corrosion resistance and solderability.
6. Safety Compliance:
- UL, IEC ISO standards compliant.
- Flame-retardant (FR-4) and halogen-free material options available.

7. We also Support various types of rigid PCB boards customization services.

Application Areas of Rigid power inverters PCBs
