Automotive electronics must satisfy a unique triad: zero-defect reliability, extreme temperature range, and 10-15 year lifecycle support. A BMS board inside an EV battery pack experiences -40°C cold starts and +125°C peak operating temperatures — sometimes within the same day. Every automotive PCB must meet AEC-Q qualification requirements covering thermal cycling, humidity bias, and highly accelerated stress testing.
High-voltage EV systems add another dimension. Powertrain PCBs for onboard chargers and DC-DC converters operate at 400V to 800V bus voltages, demanding reinforced isolation, creepage distances exceeding 8mm, and CTI-rated laminates. Heavy copper (up to 10 oz) carries hundreds of amps through bus bars and power traces while maintaining thermal stability.
ADAS and autonomous driving sensors — cameras, radar, and LiDAR — demand high-speed signal integrity on compact, often rigid-flex designs that must survive vibration profiles simulating 150,000+ miles of road conditions.
