Materials for printed boards and other interconnecting structures - Part 2-43: Reinforced base materials clad and unclad - Non-halogenated epoxide cellulose paper/woven E-glass reinforced laminate sheets of defined flammability (vertical burning test), copper-clad for lead-free assembly
Materials for printed boards and other interconnecting structures - Part 2-43: Reinforced base materials clad and unclad.
Non-halogenated epoxide cellulose paper/woven E-glass reinforced laminate sheets of defined flammability (vertical burning test), copper-clad for lead-free assembly.
IEC 61249-2-43:2016 gives requirements for properties of non-halogenated epoxide cellulose paper reinforced core/woven E-glass reinforced surface laminate sheets of 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 100 °C minimum.
