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. To establish the standard inspection of product cosmetic for operation to follow, and establish well workmanship by feedback and analyzing the inspection document to void failure.

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. It fits all product(containing product and PCBA) appearance inspection, including PCBA made by self or by other company and other.

3 名词解释(Words explanation)

无(None) 4 参考文件(Reference document) ANS/IPC-A-610D 5 职责(Responsibility)

5.1 生产单位(Production unit): 5.2 负责产品检验之执行.

5.3 Be responsible for doing product inspection

5.4 质量管理部(Quality unit): 5.5 负责产品规格之制定及产品品质之抽样检验管制

5.6 Be responsible for making product specification and controlling the spot check of

product quality 6 作业流程及内容(Flow chart and content ) 检验前的准备(preparation for inspecting): 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. Before inspecting, be sure of the tool, material, glue, cleanser, etc. Operator should have wrist strap or electrostatic glove for prevention ESD(Electronic static Discharge ), but the

finished good with。

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。 It is not means the product accept or reject that the standard of inspection have some abnormal , but should feed back to engineer to confirm.

检验环境要求光线充足,以目视为主,辅以放大镜和卡尺

外观检验项目基准参见附件一~三。

The item of cosmetic inspection standard reference Appendix 1 to 3.

7 修订权限(Authority of modification)

本规范由质量管理部工程师撰写, 经研发单位及生产单位会签, 由质量管理部最高主管核准后实施, 修改程序亦同. This criteria is prepared by Quality unit engineer and signed off with R&D(Research and Develop department )and Production unit, and then approve by Quality manager. Modify procedure as the same above.
