About This Item
IEC 61249-2-42:2010 defines requirements for reinforced base materials used in printed boards and other interconnecting structures, specifically brominated epoxide non-woven/woven E-glass reinforced laminate sheets of defined flammability with copper-clad options for lead-free assembly. For engineering, procurement, and compliance teams, it serves as a technical reference when evaluating substrate materials for documented performance, material selection, and conformity assessment. IEC 61249-2-42:2010 is relevant where consistent laminate properties and controlled flammability characteristics are part of the product specification and verification activities.
What is IEC 61249-2-42:2010?
This document is part of the IEC 61249 series for materials used in printed boards and related interconnecting structures. It focuses on a specific class of reinforced laminate sheets based on brominated epoxide with E-glass reinforcement, in clad and unclad forms, and includes a copper-clad version intended for lead-free assembly contexts. In practice, it supports technical review, material qualification, and documented evaluation of base materials used in electronics manufacturing and related quality workflows.
Applications of IEC 61249-2-42:2010
The reference is typically used by organizations involved in printed circuit board material procurement, laminate specification, incoming inspection, and laboratory evaluation. It may support engineering documentation for copper-clad board materials where defined flammability behavior is relevant to product design and safety-related assessment. It is also useful during supplier comparison, technical validation, and testing workflows when teams need a shared baseline for material selection and compliance preparation.
Why is IEC 61249-2-42:2010 important?
For manufacturers and buyers, the value of IEC 61249-2-42:2010 lies in helping align material expectations before production begins. A clear technical reference can reduce procurement risk, support consistent verification activities, and improve traceability during conformity assessment. It also helps laboratories and engineering teams compare materials using a common framework, which can strengthen quality assurance, operational consistency, and preparation for downstream compliance or certification steps.
