EN 61249-2-43:2016

Materials for printed boards and other interconnecting structures - Part 2-43: Reinforced base materials clad and unclad - Non-halogenated epoxide cellulose paper/woven E-glass reinforced laminate sheets of defined flammability (vertical burning test), copper-clad for lead-free assembly

IEC 61249-2-43:2016 gives requirements for properties of non-halogenated epoxide cellulose paper 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 non-halogenated fire retardants reacted as part of the epoxide polymeric structure. The glass transition temperature is defined to be 100 °C minimum.

Materialien für Leiterplatten und andere Verbindungsstrukturen - Teil 2-43: Kaschierte und unkaschierte verstärkte Basismaterialien - Kupferkaschierte mit Zellulose-Papier im Kernbereich und E-Glasgewebe in den Außenlagen verstärkte Laminattafeln auf der Basis von halogenfreiem Epoxidharz mit definierter Brennbarkeit (Brennprüfung mit vertikaler Prüflingslage) für bleifreie Bestückungstechnik

Matériaux pour circuits imprimés et autres structures d'interconnexion - Partie 2-43: Matériaux de base renforcés, plaqués et non plaqués - Feuilles stratifiées renforcées en verre de type E tissé/papier cellulose époxyde non halogéné, plaquées cuivre, d’inflammabilité définie (essai de combustion verticale) pour les assemblages sans plomb

L'IEC 61249-2-43:2016 fournit des exigences relatives aux propriétés des feuilles stratifiées de surface renforcées en verre de type E tissé et à coeur renforcé en papier cellulose époxyde non halogéné, plaquées cuivre, d'inflammabilité définie (essai de combustion verticale) pour les assemblages sans plomb et ayant une épaisseur comprise entre 0,60 mm et 1,70 mm. Les caractéristiques assignées d'inflammabilité sont obtenues en faisant réagir des ignifuges non halogénés qui font partie de la structure polymère époxyde. La température de transition vitreuse a été définie comme étant 100 °C au minimum.

Materiali za plošče tiskanih vezij in druge povezovalne strukture - 2-43. del: Kaširani in nekaširani ojačeni osnovni materiali - Laminatne plošče s sredico iz brezhalogenskega epoksidnega celuloznega papirja, zunaj ojačene z E-stekleno tkanino, z določeno vnetljivostjo (preskus z navpičnim gorenjem), kaširane z bakrom za tehniko sestavljanja brez svinca

Ta del standarda IEC 61249 določa zahteve za lastnosti laminatnih plošč s sredico iz brezhalogenskega epoksidnega celuloznega papirja, zunaj ojačene z E-stekleno tkanino, z določeno vnetljivostjo (preskus z navpičnim gorenjem), kaširane z bakrom za tehniko sestavljanja brez svinca, z 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 100 °C.
Nekatere zahteve glede lastnosti lahko vključujejo več razredov lastnosti. Želeni razred naj bi bil opredeljen na naročilnici, sicer se dobavi privzeti razred materiala.
