(Main)Materials for printed boards and other interconnecting structures – Part 2-47: Reinforced base materials clad and unclad – Non-halogenated epoxide non-woven/woven E-glass reinforced laminate sheets of thermal conductivity 2.0 W/(m•K) and defined flammability (vertical burning test), copper-clad for lead-free assembly
Materials for printed boards and other interconnecting structures – Part 2-47: Reinforced base materials clad and unclad – Non-halogenated epoxide non-woven/woven E-glass reinforced laminate sheets of thermal conductivity 2.0 W/(m•K) and defined flammability (vertical burning test), copper-clad for lead-free assembly
IEC 61249-2-47:2018(E) gives requirements for properties of non-halogenated epoxide non‑woven reinforced core/woven E-glass reinforced surface laminate sheets of thermal conductivity and 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 non-halogenated fire retardants reacted as part of the epoxide polymeric structure. The glass transition temperature is defined to be 105 °C minimum. Thermal conductivity is defined to be (2,0 ± 0,30) W/(m•K).

Matériaux pour circuits imprimés et autres structures d’interconnexion – Partie 2-47: Matériaux de base renforcés, plaqués et non plaqués – Feuilles stratifiées renforcées en verre de type E tissé/non tissé époxyde non halogéné, plaquées cuivre de conductivité thermique 2,0 W/(m•K) et d’inflammabilité définie (essai de combustion verticale) pour les assemblages sans plomb
L’IEC 61249-2-47:2018 donne les exigences relatives aux propriétés des feuilles stratifiées de surface renforcée en verre de type E tissé et à cœur renforcé non tissé époxyde non halogéné, de conductivité thermique et d’inflammabilité définie (essai de combustion verticale), plaquées cuivre pour les assemblages sans plomb, d’épaisseurs comprises entre 0,60 mm et 1,70 mm. Les caractéristiques d’inflammabilité sont obtenues en faisant réagir des ignifuges non halogénés qui font partie de la structure polymère époxyde. La température de transition vitreuse est définie comme étant d’au moins 105 °C. La conductivité thermique est définie comme étant de (2,0 ± 0,30) W/(m•K).
Materiali za plošče tiskanih vezij in druge povezovalne strukture - 2-47. del: Pokovinjeni in nepokovinjeni ojačeni osnovni materiali - Z bakrom pokovinjeni laminat s toplotno prevodnostjo (2,0W/m K) in z določeno gorljivostjo (navpični preskus gorljivosti), s površino z netkanim/tkanim E-steklom za sestavljanje brez svinca
Ta del standarda IEC 61249 podaja zahteve za lastnosti z bakrom pokovinjenega laminata s toplotno prevodnostjo in z določeno gorljivostjo (navpični preskus gorljivosti), s površino z netkanim/tkanim E-steklom za sestavljanje brez svinca ter debelino od 0,60 mm do 1,70 mm. Ocena gorljivosti se doseže z uporabo nehalogeniranih zaščitnih sredstev proti ognju, ki reagirajo kot del epoksidne polimerne strukture. Točka posteklenitve je opredeljena kot najmanj 105 °C. Toplotna prevodnost je opredeljena kot (2,0 ± 0,30) W/(m•K).
