对标准IPC-7351B中焊盘命名规则的归纳

Summarization of Padstack Naming Conventions Defined in the Standard IPC-7351B

分析了标准IPC-7351B2010中定义的焊盘命名规则和实例,归纳出"默认焊盘+孔+改型参数"的名称结构。将形状编码简化到10类,去除重复的倒角命名规则,将Offset尺寸从一维坐标扩展到二维坐标,简化和优化了焊盘命名规则,有助于理解和实施标准IPC-7351B。

The naming conventions and instances of padstack defined in the standard IPC-7351 B 2010 are analyzed,and the name structure of the"Default padstack+Hole+Modified parameters"is summarized.The shape coding is simplified to ten classes,the repeated corner naming rules are removed,the offset dimensions are extended from onedimensional coordinates to two-dimensional coordinates,and the naming conventions of the padstack are simplified and optimized,which is helpful to understand and implement the standard IPC-7351 B.
