Background
PCBA (Printed Circuit Board Assembly) serves the functions of electrical connection, signal transmission, and mechanical support in automotive electronic systems. As the core physical carrier of automotive electronic systems, the reliability of PCBA directly determines the stability and safety of the vehicle's electronic functions. Statistics show that the after-sales failure rate of untested PCBA can be as high as 15%, which can be reduced to below 5% after strict evaluation. Among these failures, raw material/process defects account for over 70% of PCBA failures, covering solder joints, components, and PCB process reliability issues, with insufficient thermal management and structural stability of the PCBA being the main causes. With the trend towards electrification and intelligence in automobiles, the importance of PCBA thermal management and structural stability assessment is becoming increasingly prominent.
