Automation

The auto drive system in the car completely depends on highly complex PCBs, which run various devices to provide the functions required by the auto drive system. These devices include radar, LiDAR, ultrasonic sensors, laser scanners, Global Positioning System (GPS), cameras and displays, encoders, audio receivers, remote connections, motion controllers, actuators, etc. Sensor fusion electronic devices provide a visual map of the surroundings for cars, detecting objects, vehicle speed, and distance from obstacles.

In the auto drive system, many types of PCBs are used to meet different needs:
Rigid PCB: Used for installing complex electronic devices and connecting various modules, high-density interconnect (HDI) PCBs can achieve smaller and more precise layouts.
High frequency PCB: With low dielectric constant, it is suitable for high-frequency applications such as automotive sensors and radar.
Thick copper PCB: provides a minimum resistance path to avoid high temperature caused by high current and PCB melting.
Ceramic PCB: With high insulation performance, it can withstand high power and current, and is suitable for harsh environments.
Aluminum based metal core PCB: commonly used for automotive LED headlights.
Rigid flexible PCB: used to connect display screens and processor boards, and to connect various electronic modules through flexible PCBs.
