How Important Is PCB Assembly in Automotive Electronics?

Cars today are no longer simple mechanical products. Electronic systems account for an increasing proportion, and PCB assembly  is the "heart" of these electronic systems. From in-car entertainment systems to autonomous driving sensors, almost all electronic functions cannot do without it.

Let's talk about the most basic ones first. For display devices such as dashboards and central control screens, the PCB assembly behind them has to process a large amount of image data and resist vibration. More importantly, the body control system, such as ABS anti-lock braking and ESP body stability, these safety-related systems have extremely high requirements for PCB assembly reliability and must be able to work stably at extreme temperatures from -40℃ to 85℃.

The three-electric system (battery, motor, and electronic control) of new energy vehicles is dominated by PCB assembly. The densely packed circuit boards in the BMS battery management system need to monitor the status of hundreds of batteries in real time, and the accuracy is required to reach the millivolt level. The millimeter-level wiring of the high-frequency PCB assembly in the millimeter-level radar and camera used for autonomous driving is a little worse, and the signal will have problems.

However, automotive-grade PCB assembly is different from consumer electronics. It needs to pass strict certification such as AEC-Q100, and the production process and material selection are more demanding. Now that smart cars are still developing rapidly, the application of PCB assembly will only become more and more extensive, and the technical requirements will become higher and higher.
