This specification covers qualification and performance of high frequency (microwave) boards, including single-sided, double-sided, with or without plated-through holes, multilayer with or without blind/buried vias and metal core boards. It addresses final finish and surface plating coating requirements, conductors, holes/vias, frequency of acceptance testing and quality conformance as well as electrical, mechanical and environmental requirements. Revision C incorporates many new requirements in areas such as HASL coatings, alternative surface finishes, edge plating, marking, microvia capture and target lands, copper cap plating of filled holes, copper filled microvias, PTFE smear and dielectric removal. For use with IPC-6011. Number of pages: 64. Released July 2016.
IPC-6018C Qualification and Performance Specification for High Frequency (Microwave) Printed Boards
This specification covers end product inspection and test of high frequency (microwave) printed boards for microstrip, stripline, mixed dielectric and multilayer stripline applications with or without buried/blind vias, and metal cores. The printed board may contain embedded active or passive circuitry with distributive capacitive planes, capacitive or resistive components conforming to IPC-6017. The printed board may contain build up High Density Interconnect (HDI) layers.
