AEC-Q200 Passive Component Stress Test Certification Specification for Automotive Industry

AEC-Q200 Passive Component Stress Test Certification Specification for Automotive Industry

    In recent years, with the progress of multi-functional in-vehicle applications, and in the process of popularization of hybrid vehicles and electric vehicles, new uses led by power monitoring functions are also expanding, miniaturization of vehicle parts and high reliability requirements under high temperature environmental conditions (-40 ~ +125℃, -55℃ ~ +175℃) are increasing. A car is composed of many parts. Though these parts are large and small, they are closely related to the life safety of car driving, so every part is required to achieve the highest quality and reliability, even the ideal state of zero defects. In the automotive industry, The importance of quality control of auto parts is often over the functionality of parts, which is different from the needs of consumer electronics for the general people's livelihood, that is to say, for auto parts, the most important driving force of the product is often not [the latest technology], but [quality safety]. In order to achieve the improvement of quality requirements, it is necessary to rely on strict control procedures to check, the current automotive industry for parts qualification and quality system standards is AEC(Automotive Electronics Committee). The active parts designed for the standard [AEC-Q100]. The passive components designed for [AEC-Q200]. It regulates the product quality and reliability that must be achieved for passive parts.
