Description

IEC 61249-2-32 Ed. 1.0 b – Materials for printed boards and other interconnecting structures – Part 2-32: 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 3,7 at 1 GHz) and flammability (vertical

IEC 61249-2-32:2009 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 3,7 and the dissipation factor is equal to or less than 0,0070 at 1 GHz.
