线束加工工艺流程依次为为下线、压接、预装、总装、检验、包装，本文主要介绍线束预装工艺卡的填写要求。
1、线束加工预装工艺卡的填写
(1)系列号：指预装工艺文件适用的电线束系列型号,同一项目中如果电线束的差异太大,而不能进行合并,必须用不同的系列号进行区分,不同的系列号之间的预装工艺文件不能通用。文章源自线束工程师之家-https://www.suncve.com/filling-in-the-pre-installation-process-card-of-wire-harness/

(2)适用车型:指预装工艺所适用的电线束型号文章源自线束工程师之家-https://www.suncve.com/filling-in-the-pre-installation-process-card-of-wire-harness/
(3)技术要求:指对操作的要求。如护套均采用“进线端”视图等文章源自线束工程师之家-https://www.suncve.com/filling-in-the-pre-installation-process-card-of-wire-harness/
(4)绘图区:内容可根据不同的电线束编制,绘制方法、色标、字体等内容按《工艺绘图标准》执行。文章源自线束工程师之家-https://www.suncve.com/filling-in-the-pre-installation-process-card-of-wire-harness/
(5)操作内容:指对预装图中半成品操作方法的简述和注意事项文章源自线束工程师之家-https://www.suncve.com/filling-in-the-pre-installation-process-card-of-wire-harness/
2、预装工艺卡设计的技巧
一般情况下线束产品图的视图方向全部为护套前端视图,而预装图的视图方向全部为护套后端祧图,编制预装工艺卡前把产品图直接镜像,就会得到进线端视图的产品图特别要注意护套的孔位号是否正确。镜像方法:在 AutoCaD中输入 MIRRTEXT,参数为0,然后选择“镜像”工具将产品图左右镜像处理。文章源自线束工程师之家-https://www.suncve.com/filling-in-the-pre-installation-process-card-of-wire-harness/
