生成Gerber文件的方法及步骤:
1.定义分类钻孔
进入菜单Manufacture-NC-Drill customization,选Auto generate sysmbols 2.放置钻孔表
进入菜单Manufacture-NC-Drill Legend, 点OK后在PCB上放置
3.进入菜单Manufacture-NC-NC parameters,设置相关参数 Leader:12, code: ASCII, format: 2:3
Coordinater: absolute, output units:metric (如果PCB设计是用毫米制的,就选这个) 4.生产钻孔文件NC Drill
进入菜单Manufacture-NC-NC Drill 选择 .DRL文件的路径
选 Tool sequence: increasing, 选repeat codes 点Drill生成钻孔文件 5.生成Artwork文件
在菜单Shape-Global Dynamic shape中Void controls中的artwork format选Gerber RS274X
进入菜单Manufacture-Artwork
在General parameters对话框中设置相关项: ? Device type: Gerber RS274X ? Error action: Abort film
? Format: 5, 5 (要比PCB精度设置多一位) ? Suppress选Leading zeros 和 Equal coordinates
? Output units: millimeters (如果PCB设计是用毫米制的,就选这个) ? Scale factor for output : 1
在Film Control对话框中设置相关项: ? Check database before artwork选上 ? Vertor based pad behabior选上 ? 对于所有内层(信号和Plane层),suppress unconnected pads选上 ? 信号层选Positive,电源层选Negative ? Undefined linewidth: 0.15 ? Shape bounding box: 2.54 ? Offset X: 0 Y:0 ? Rotation: 0
