What is BS EN IEC 61249-2-47-Materials for printed boards about?  
BS EN IEC 61249-2-47 is an international standard that discusses materials for printed boards and other interconnecting structures.
BS EN IEC 61249-2-47 gives requirements for properties of non-halogenated epoxide non-woven reinforced core/woven E-glass reinforced surface laminate sheets of thermal conductivity and defined flammability (vertical burning test), copper-clad for lead-free assembly in thicknesses of 0,60 mm up to 1,70 mm. The flammability rating is achieved through the use of non-halogenated fire retardants reacted as part of the epoxide polymeric structure. The glass transition temperature is defined to be 105 °C minimum. Thermal conductivity is defined to be (2,0 ± 0,30) W/(m•K).
Who is BS EN IEC 61249-2-47 - Materials for printed boards for? 
BS EN IEC 61249-2-47 on materials for printed boards is relevant to:
- Manufacturers of printed circuit boards (PCBs)
- Manufacturers of electronic components and interconnecting structures
- Manufacturers and suppliers of laminate sheets
- Quality control and testing personnel
- Inspection authorities
Why should you use BS EN IEC 61249-2-47 - Materials for printed boards?  
The Printed Circuit Board (PCB) is essential in all electronic devices, whether they are used for residential or industrial applications. In a multi-processor context, the interconnection arrangement can determine total system performance.
BS EN IEC 61249-2-47 covers best industry guidance on materials and construction, reference standards’ test methods to verify electrical properties along with their requirements, and non-electrical properties of the copper-clad laminate. Reference test methods for properties such as flexural strength, flammability, measling, amongst others and their respective requirements are also covered.
Compliance with requirements and tests provided by BS EN IEC 61249-2-47 can thus demonstrate the reliability, quality and performance of materials for printed boards and interconnecting structures.
