Automotive PCBA High Temperature Resistance and Vibration Resistance for Engine Control
♦ What's Automotive PCBA?
Automotive PCBA, is the core of automotive electronic systems.It fixes the electronic components on the PCB to form a complete circuit, which is used in various systems of the car.
Application | PCB Requirements | Examples |
---|---|---|
Engine Control Unit (ECU) | High-temperature resistance, EMI shielding | Fuel injection, ignition timing |
Infotainment System | High-speed signal integrity, multilayer | Touchscreens, GPS, Bluetooth |
ADAS (Radar/LiDAR) | RF/microwave PCBs, low-loss materials | Collision avoidance, adaptive cruise control |
EV Battery Management (BMS) | High-current PCBs, thermal management | Cell balancing, charge monitoring |
LED Lighting | Aluminum PCBs for heat dissipation | Headlights, interior lightin |
