Materials for printed boards and other interconnecting structures - Part 2-31: Reinforced base materials, clad and unclad - Halogenated modified or unmodified resin system, woven E-glass laminate sheets of defined relative permittivity (equal to or less than 4,1 at 1 GHz) and flammability (vertical burning test), copper-clad
Materials for printed boards and other interconnecting structures - Part 2-31: Reinforced base materials, clad and unclad - Halogenated modified or unmodified resin system, woven E-glass laminate sheets of defined relative permittivity (equal to or less than 4,1 at 1 GHz) and flammability (vertical burning test), copper-clad.
IEC 61249-2-31:2009 specifies requirements for properties of modified epoxide woven E-glass laminate sheet of a thickness of 0,05 mm up to 3,2 mm, of defined flammability (vertical burning test), copper-clad.
The glass transition temperature is defined to be 150 ¦C minimum.
The relative permittivity is equal to or less than 4,1 and the dissipation factor is equal to or less than 0,0120 at 1 GHz.
