Materials for printed boards and other interconnecting structures - Part 2-42: Reinforced base materials, clad and unclad - Brominated epoxide non-woven/woven E-glass reinforced laminated sheets of defined flammability (vertical burning test), copper-clad
This part of IEC 61249 gives requirements for properties of brominated epoxide non-woven
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 brominated fire retardants
reacted as part of the epoxide polymeric structure. The glass transition temperature is defined
to be 105 °C minimum.
Some property requirements may have several classes of performance. The class desired
should be specified on the purchase order, otherwise the default class of material will be
supplied.
