Materials for printed boards and other interconnecting structures - Part 2-22: Reinforced base materials clad and unclad - Modified non-halogenated epoxide woven E-glass laminated sheets of defined flammability (vertical burning test), copper-clad"
Materials for printed boards and other interconnecting structures - Part 2-22: Reinforced base materials clad and unclad - Modified non-halogenated epoxide woven E-glass laminated sheets of defined flammability (vertical burning test), copper-clad.
This part of IEC 61249 gives requirements for properties of modified non-halogenated epoxide woven E-glass laminated sheet 0.05 mm up to 3.2 mm, of defined flammability (vertical burning test), copper-clad.
The flammability rating is achieved through the use of phosphorus compounds and/or aluminium hydroxide fire retardants contained as part of the polymeric structure.
The glass transition temperature is defined to be between 150 °C to 190 °C.
