Abstract
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).
