[嵌入式]AEC-Q100

AEC: Automotive Electronics Council, 汽车电子协会，由Chrysler(克莱斯勒)、福特(Ford)和通用(GM)发起并在1994年成立。

克莱斯勒现在已经处于PSA-FCA的一个子品牌。

AEC的目的

针对车载零部件和应用，建立车载电子部件的可靠性及认定标准和质量控制标准，提高汽车电子的稳定性和标准化。想进入汽车领域，则必须取得汽车电子协会的AECQ可靠性测试认证，以及零失效（Zero Defect）的供应链质量管理标准IATF16949规范。

AECQ

即国际汽车电子协会车规验证标准

针对不同的汽车电子零部件类型，有不同的AECQ标准：

AEC-Q100

AEC-Q100是AEC的第一个标准。AEC-Q100详细规定了一系列的测试，同时定义了应力测试驱动型认证的最低要求以及IC认证的参考测试条件。

工作温度等级

测试流程

从Die设计到Wafer生产和测试，封装，电学特性测试，芯片的温度、电学压力测试、机械压力测试。

这些测试包括7个测试群组：

测试群组A(环境压力加速测试，Accelerated Environment Stress)

测试群组B(使用寿命模拟测试，Accelerated Lifetime Simulation)

测试群组C(封装组装整合测试，Package Assembly Integrity)

测试群组D(芯片晶圆可靠度测试，Die Fabrication Reliability)

测试群组E(电气特性确认测试，Electrical Verification)

测试群组F(瑕疵筛选监控测试，Defect Screening)

测试群组G(封装凹陷整合测试，Cavity Package Integrity)

详细测试项

AEC-Q100关于认证的说明

我的理解是AEC不提供芯片的测试认证。芯片供应商根据客户需求，针对自家芯片进行AEC标准测试，并且提供测试数据给其客户。客户根据测试数据判断是否符合AEC-Q100可靠性测试标准。

1.3.2 AEC Certification
Note that there are no "certifications" for AEC-Q100 qualification and there is no certification board run by AEC to qualify parts. Each supplier performs their qualification to AEC standards, considers customer requirements and submits the data to the customer to verify compliance to Q100.

Requalification的通过标准：

3.2.3 Criteria for Passing Requalification
All requalification failures shall be analyzed for root cause. Only when corrective and preventativeactions are in place, the part may then be considered AEC Q100 qualified again.

3.2.4 User Approval
A change may not affect a device's operating temperature grade, but may affect its performance in an application. Individual user authorization of a process change will be required for that user’s particular application(s), and this method of authorization is outside the scope of this document.

AEC-Q100关于ESD测试的说明

1.3.1 AEC Q100 Qualification
Successful completion and documentation of the test results from requirements outlined in this document allows the supplier to claim that the part is “AEC Q100 qualified”. For ESD, it is highly recommended that the passing voltage be specified in the supplier datasheet with a footnote on any pin exceptions. This will allow suppliers to state, e.g., "AEC-Q100 qualified to ESD Classification 2".
