描述在信息文件的处理和生成中使用库的情况。其中包含的数据涵盖了内部库（信息文件中存在）和外部库的定义和使用。这些库可用于使生成的数据更加紧凑，并促进数据交换和存档。库中的子例程可以在任何数据信息模块中使用一次或多次，也可以在一个或多个数据信息模块中使用。补充IPC-D-350系列。（本文件不涉及本系列中其他标准的细节）。

Describes the usage of libraries within the processing and generation of information files. The data contained within covers both the definition and usage of internal (existing within the information file) and external libraries. The libraries can be used to make generated data more compact and facilitate data exchange and archival. The subroutines within a library can be used one or more times within any Data Information Module and also in one or more Data Infomation Modules. Supplements the IPC-D-350 series.
