Why Choose Rogers RO4350B for EV Power Control?
1. Superior Thermal Management (3oz Heavy Copper)
Electric vehicle power modules generate significant heat. By utilizing 3oz copper, this board offers a massive increase in cross-sectional area compared to standard 1oz boards. This allows for efficient heat dissipation and the ability to handle high-amperage traces without excessive temperature rise.
2. Stable Electrical Performance
The Rogers RO4350B material is the industry standard for high-frequency applications. Its low Z-axis Coefficient of Thermal Expansion (CTE) of 32 ppm/°C ensures that through-hole reliability is maintained even during the rapid thermal cycling common in EV battery management systems (BMS) and motor controllers.
3. 8-Layer High-Density Interconnect (HDI)
With an 8-layer architecture, this board provides dedicated planes for grounding and power shielding. This is critical for EV Power Control Units (PCUs) to prevent Electromagnetic Interference (EMI) from disrupting sensitive logic and sensor signals.
4. ENIG Finish for Precision Assembly
The ENIG (Electroless Nickel Immersion Gold) surface finish provides a perfectly flat mounting surface, essential for fine-pitch components, BGA packaging, and high-reliability wire bonding. It also ensures a long shelf life and excellent contact resistance for high-current interconnects.
