Automotive PCB

Automotive electronic products have different reliability requirements for automotive printed circuit board in different parts, Huihe Circuits’ car PCBs have passed the IATF16949 automotive quality management system standard, Strictly follow the requirements of the control plan to produce, monitor, record and analyze, ensure the stability of process parameters and the traceability of the production process.

Automotive Circuit Board Advantages

Huihe Circuits knows that the reliability of automotive PCB is equivalent to the reliability of automobiles, so it is necessary to ensure that the reliability of automotive electronics meets the requirements of service life and environmental tolerance. The PCB in cars used in the automotive electronic system needs to withstand the test of various environmental changes, such as temperature and humidity, climate, acid mist, vibration, electromagnetic interference, current impact, etc.; in order to ensure the PCB board application normal life cycle, the car PCB needs to meet high reliability, high integration, high The characteristics and requirements of heat dissipation, high current (thick copper), light weight and miniaturization, and embedded devices. For example, the high-voltage control system of a new energy electric vehicle uses a strong current board to integrate the original scattered high-voltage device parts, scattered DC/charge/discharge/MCU and other functional parts on an automotive printed circuit board. The density has increased several times, but The structural space should be saved by 30%, and the manual assembly efficiency should be increased by 50%.
