1．目的
建立PCBA外观检验标准，为生产过程的作业以及产品质量保证提供指导。
1、 适用范围 Scope:
2.1本标准通用于本公司生产任何产品PCBA的外观检验（在无特殊规定的情况外）。包括公司内部生产和发外加工的产品。
2.2 特殊规定是指：因零件的特性，或其它特殊需求，PCBA的标准可加以适当修订，其有效性应超越通用型的外观标准。
2、 定义 Definition:
3.1标准
【允收标准】 (Accept Criterion)：允收标准为包括理想状况、允收状况、拒收状况等三种状况。
【理想状况】 (Target Condition)：此组装情形接近理想与完美的组装结果。能有良好组装可靠度，判定为理想状况。
【允收状况】 (Accept Condition)：此组装情形未符合接近理想状况，但能维持组装可靠度故视为合格状况，判定为允收状况。
【拒收状况】(Reject Condition)：此组装情形未能符合标准，其有可能影响产品的功能性，但基于外观因素以维持本公司产品的竞争力，判定为拒收状况。
3.2 缺陷定义
【致命缺陷】(Critical Defect)：指缺陷足以造成人体或机器产生伤害，或危及生命财产安全的缺陷，称为致命缺陷，以CR表示的。
【主要缺陷】(Major Defect)：指缺陷对制品的实质功能上已失去实用性或造成可靠度降低，产品损坏、功能不良称为主要缺陷，以MA表示的。
【次要缺陷】(Minor Defect)：系指单位缺陷的使用性能，实质上并无降低其实用性 ，且仍能达到所期望目的，一般为外观或机构组装上的差异，以MI表示的。
