DS DSEN 61249-2-9 2003-JUL-08 Materals for prnted boards and other nterconnectng structures - Part 2-9 Renforced base materals clad and unclad - Bsmalemdetrazne modfed epoxde or unmodfed woven E-glass renforced lamnated sheets of defned flammablty vertcal burnng test copper-clad
This part of IEC 61249 gives requirements for properties of bismaleimide/triazine modified epoxide, or unmodified, woven E-glass reinforced laminate sheets of defined flammability (vertical burning test), copper-clad in thicknesses of 0,05 mm to 3,2 mm. The flammability rating is acheived through the use of brominated fire retardants contained as an integral part of the epoxide polymeric structure. The glass transition temperature is defined to be 160°C minimum.
