IEC 61249-4-17:2009

IEC 61249-4-17:2009 defines a sectional specification for prepreg materials used in printed boards and other interconnecting structures, with a focus on unclad prepreg for multilayer board manufacture. It is specifically concerned with non-halogenated epoxide woven E-glass prepreg of defined flammability for vertical burning test performance in lead-free assembly contexts. For engineering, procurement, and conformity assessment teams, IEC 61249-4-17:2009 provides a technical reference for material selection, documented evaluation, and quality workflows tied to multilayer PCB production.

Overview of IEC 61249-4-17:2009

This technical document sits within the IEC 61249 series for materials used in printed boards and related interconnecting structures. Its scope is centered on prepreg materials that are not yet clad and are intended for multilayer board fabrication, with attention to non-halogenated epoxide woven E-glass construction and defined flammability behavior. As a primary reference for engineering documentation, it helps organizations align material specification, supplier review, and laboratory evaluation with the expected performance profile for lead-free assembly environments.

Compliance applications of IEC 61249-4-17:2009

IEC 61249-4-17:2009 is relevant in procurement and technical review when selecting prepreg for multilayer printed board builds where material composition and flammability characteristics must be documented. It may support product evaluation, incoming material control, and verification activities in PCB manufacturing and related electronics supply chains. The document is also useful during regulatory preparation and conformity assessment when teams need a traceable compliance reference for lead-free assembly programs, manufacturing specifications, and supplier declarations.

Importance of compliance with IEC 61249-4-17:2009

Using this reference helps reduce risk in material qualification by giving manufacturers and laboratories a consistent basis for technical validation and acceptance decisions. That consistency supports safety-related considerations, operational consistency, and testing workflows where prepreg performance must be reviewed against a defined sectional specification. It can also improve engineering validation and procurement confidence by aligning material selection with documented requirements, which is important when preparing evidence for quality assurance, conformity assessment, and internal compliance audits.
