IPC-4101E-WAM1涵盖了被称为层压板或预浸料的基材的要求，并在标准主体之后的规范表中列出。规格表主要用于电子互连用刚性和多层印制板。IPC-4101E-WAM1标准包含70个单独的规范表，可以使用关键字进行搜索。这些关键词允许用户找到性质相似但特性不同的材料，以微调其层压板和/或预浸料选择需求。IPC-4101E-WAM1包括附录A，该附录提供了补充检验要求，但前提是材料用户的采购订单或主图纸中有要求。

IPC-4101E-WAM1 covers the requirements for base materials that are referred to as laminate or prepreg and listed in the specification sheets which are found after the main body of the standard. The specification sheets are to be used primarily for rigid and multilayer printed boards for electronic interconnections. The IPC-4101E-WAM1 standard contains 70 individual specification sheets that can be searched using keywords. The keywords allow users to find materials of a similar nature, but with specific differing properties that fine-tune their laminate and/or prepreg selection needs. The IPC-4101E-WAM1 includes an Appendix A that provides supplemental inspection requirements, but only if required in the material user's purchase order or master drawing.
