 第十一讲、Allegro的class和subclass概念


所有的对象分成大类和子类  
 任何一个对象（焊盘丝印走线等）必定属于一个某一个class下的subclass.  
 方便对某一个类进行批量的操作  
 同一个对象放在不同的层的话也代表不同的含义

不同的类和子类的使用

 子类Design\_outline(板边)  
 子类Dimension（板边几何尺寸）

 子类Silkscreen\_Botton(底层丝印层)  
 子类Soldemask\_Top(顶层 阻焊层)  
 option->Etch(电气层)->  
 子类TOP/…/Botton(顶层到底层)（铜皮、走线、焊盘、过孔等）  
 option->Manufacturing(加工相关的内容)->  
 子类Ncdrill\_Figure(钻孔图形)  
 子类NCdrill\_Legend/Nclegend(钻孔表)  
 option->Package\_Geometry(装配相关)->  
 子类Assembly\_Top（底层指导装配图）（元器件封装的时候就要做好）  
 子类Place\_Bound\_Top(元器件边框位置)（元器件封装的时候就要做好）  
 子类Silkscreen\_Top（元器件丝印层）  
 option->Pin(引脚相关)->  
 子类TOP/…/Botton（对应层的器件的引脚）  
 子类Soldemask\_层 （对应层的阻焊层）  
 子类Pastmask\_层 （对应层的助焊层，开钢网用）  
 option->RefDes（位号相关）  
 子类Silkscreen\_Top(做板时候的丝印)  
 option->Route Keepin(画一个形状只能在里面布线，并非板边)  
 option->Route\_Keepout(画一个形状只能在外面布线)  
 option->Via Class(钻孔相关)


第 十二讲、Padstack Editor制作贴片焊盘和 通孔焊盘


为后期制作元器件的封装做准备  
 焊盘尺寸获得：  
 1、元器件的数据手册 获得焊盘的尺寸，封装的间距等。  
 2、软件LP Wizard  
 3、立创商城  
 0402电阻焊盘制作  
 打开Padstack Editor软件
