  2. 一、目的: 为使CAM文件处理规范化, 使操作员的操作技能明确化而制定本操作程序。 二、范围: 本程序适用于双面多层板厂CAM制作生产菲林;以确保CAM制作出来的各类工具能满足客户品质要求;并在公司制程能力范围内方便生产使用。

  3. 三、内容: CAM工作流程;制作工具;CAM概述;钻带制作;内层线路菲林制作;外层线路菲林制作;嚗光阻焊菲林制作;字符菲林制作;拼版及加板边;输出文件;备份生产文件及送档案室存档。

  4. 收到MI指示 MI 问题 在PC机登记 1 CAM工作流程: 钻带、生产菲林编辑 NO 自检 OK 完成的工具在PC机登记 备份生产资料 送档案室入档

  5. 2 . 制作工具: 3. WZ目前使用Genesi2000系统进行工具的制作。 4.CAM概述: 5. WZ CAM现使用Genesi2000系统制作工具,主 要包括:Create、Input、Orig、Edit、Spnl、 Panel、Analysis、Dfm、Layer compare、 Netlist compare、Output等等。 6.钻带制作: 7. 制作步骤:

  6. 8.创建一个Job,创建一个Step,Input(输入); 9.定义层的属性,层对齐,设定Pcb的零点,设定 Profile; 10.资料初步检查; 11.对接到的MI指示、菲林、孔图、Cad Data、外形图纸进行检查; 12.孔图与Cad Data(菲林上)的孔数、孔位是否一致; 13.MI指示上的孔位、孔数与孔图及Cad Data是否一致; 14.MI指示上的外形数据与外形图上的数据是否一致; 15.MI指示上的钻刀刀径是否正确; 16.拼版编辑程序、文件存档并通知钻首板;
