PCBA检验规范
1目的(Purpose)
建立产品外观目视检验标准,使产品检验之判定有所依循,同时藉由检验资料的回馈分析建立良好的workmanship,防止不良之发生.
Toestablishthestandardinspectionofproductcosmeticforoperationtofollow,andestablishwellworkmanshipbyfeedbackandanalyzingtheinspectiondocumenttovoidfailure.
2范围(Scope)
本规范适用于所有产品(含半成品及成品PCBA)的外观目视检验,包含自行生产制造之PCBA,委托外包生产制造之PCBA,以及外购入厂组立或单独包装出货之PCBA等.
Itfitsallproduct(containingproductandPCBA)appearanceinspection,includingPCBAmadebyselforbyothercompanyandother.

6作业流程及内容(Flowchartandcontent)
6.1检验前的准备(preparationforinspecting):
检验前须先确认所使用的工具,材料,胶,清洁剂等,是否合乎规定.检验PCBA时必须配戴防静电手套或防静电手环,而成品有外壳部分则不在此限.
Beforeinspecting,besureofthetool,material,glue,cleanser,etc.OperatorshouldhavewriststraporelectrostaticgloveforpreventionESD(ElectronicstaticDischarge),butthefinishedgoodwith。
6.2若有检验标准未规范的异常现象发生时,不代表该产品允收或拒收,应向值班工程师询问。
