Allegro PCB封装库（分类、命名很规范，已验证）该PCB库特点一：类型齐全，包含有阻容感分立元器件;SOIC(SO,SOP,SSOP,TSOP,TSSOP）;QFN;QFP(PQFP,SQFP,CQFP）;PLCC;BGA及常用连接器等PCB封装，共400多个的库文件。该PCB库特点二：库文件命名规范，例如BGA类型的PCB封装命名为：BGA+引脚数+PIN间距+主体长宽，这样的命名规则容易查找核对。该PCB库特点三：按照pad，ssm，fsm，symbol4个文件夹分类放置，便于库的管理该PCB库特点四:所有封装本人都有设计使用并生产过，拿后者可放心使用。该PCB库特点五:可提供PCB封装库的EXCEL查找表。更重要的是，大部分.dra封装都已附有3D模型。可节省大量的3D模型匹配时间。
