About This Item
IEC 61249-2-34:2009 defines requirements for reinforced base materials used in printed boards and other interconnecting structures, specifically copper-clad woven E-glass laminate sheets with a non-halogenated modified or unmodified resin system. It is relevant where material selection must support controlled dielectric behavior and flammability performance in engineering documentation, procurement review, and compliance workflows. For organizations evaluating laminate materials, IEC 61249-2-34:2009 helps provide a consistent technical reference for documented evaluation and product selection.
What is IEC 61249-2-34:2009?
This document is a primary technical reference for copper-clad reinforced base materials used in printed boards and related interconnecting structures. Its scope centers on woven E-glass laminate sheets with defined relative permittivity and flammability characteristics, which are important in technical assessment and conformity assessment activities. In practice, it supports comparison of candidate materials against a documented engineering specification, helping laboratories, manufacturers, and procurement teams align product evaluation with the expected material profile.
Applications of IEC 61249-2-34:2009
The reference is commonly relevant in printed circuit board material selection, laminate qualification, and supplier documentation for electronic hardware programs. It may be used during laboratory evaluation, incoming material review, and engineering validation where copper-clad reinforced base materials need to be assessed against defined dielectric and flammability expectations. It is also useful in quality workflows that require traceable material data for manufacturing consistency, technical review, and procurement decisions tied to board fabrication or interconnecting structure design.
Why is IEC 61249-2-34:2009 important?
IEC 61249-2-34:2009 matters because material properties can affect safety, electrical performance, and build consistency in printed board applications. A clear technical reference helps reduce risk during product evaluation and supports repeatable testing workflows across suppliers and production lots. It is also valuable for compliance preparation, because documented material criteria can simplify technical validation, quality assurance checks, and conformity assessment for organizations working with regulated or specification-driven electronic assemblies.
