About This Item
IEC 61249-4-16:2009 addresses a sectional specification for prepreg materials used in printed boards and other interconnecting structures, with a focus on unclad materials for multilayer board manufacture. It is relevant where engineering teams need a technical document for material selection, product evaluation, and conformity assessment in lead-free assembly environments. The title indicates a multifunctional non-halogenated epoxide woven E-glass prepreg with defined flammability performance, making the document useful for procurement review, technical validation, and quality workflows tied to printed circuit board materials.
What is IEC 61249-4-16:2009?
IEC 61249-4-16:2009 is a sectional specification within the materials for printed boards series, describing requirements for an unclad prepreg intended for multilayer board production. Based on the official title, it is aimed at defining a particular material type: multifunctional non-halogenated epoxide woven E-glass prepreg with flammability characteristics assessed by a vertical burning test for lead-free assembly. In practice, it serves as a technical reference for documented evaluation, supplier comparison, and engineering review of laminate precursor materials.
Applications of IEC 61249-4-16:2009
This document is typically used in printed board design, board fabrication, and materials qualification workflows where multilayer structures are being specified or purchased. It can support laboratory evaluation of prepreg materials, production planning, and technical assessment of assemblies that rely on lead-free processing. Organizations involved in electronics manufacturing may use IEC 61249-4-16:2009 during procurement and compliance preparation when they need a clear material reference for board stack-up decisions, performance consistency, and quality assurance across manufacturing lots.
Why is IEC 61249-4-16:2009 important?
IEC 61249-4-16:2009 matters because it helps align material selection with controlled manufacturing and verification activities for multilayer printed boards. A defined sectional specification can reduce risk during technical review by giving suppliers, laboratories, and engineering teams a common basis for inspection and conformity assessment. It is especially useful where flammability behavior, non-halogenated composition, and lead-free assembly compatibility must be considered together. That makes it a practical compliance reference for procurement decisions, testing workflows, and operational consistency.
