                                            FCT测试流程及要求
 
All applicable documents shall be adhered to. If a conflICT exists between this specification and an applicable document, this specification shall take precedence. This assembly is static sensitive and should only be handled in a static controlled environment.
所有适用文件须要被满足,如果本文件和适用文件之间存在冲突,请以该测试标准为准,该产品对静电敏感需要在静电可控的环境下组装
 
Pre-Test Requirements预测试要求
 
The Pre-Test Requirements apply to the F1208201 after the attachment of the alarm unit wiring to the assembly. Once the UUT has successfully completed Pre-Test, it’s ready for Functional Testing.
当报警器连接到产品上后进行F1208201预测试,当UUT成功通过预测试后,将进入到功能测试
The test procedure outlined here is a minimum requirement. At this time the manufacturing organization may elect to include a Manufacturing Defect Analysis (MDA) procedure, to verify the correct manufacturing process of the assembly.
这里列出来的测试流程只是*基本的测试要求,制造厂商可以选择其它的要求包括产品不佳分析流程来确认制造中的流程是否正确
