EN 61249-2-41:2010

Materials for printed boards and other interconnecting structures - Part 2-41: Reinforced base materials clad and unclad - Brominated epoxide cellulose paper/woven E-glass reinforced laminate sheets of defined flammability (vertical burning test), copper-clad for lead-free assembly

IEC 61249-2-41:2010 gives requirements for properties of brominated 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 brominated 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 2-41: Kaschierte und unkaschierte verstärkte Basismaterialien - Kupferkaschierte mit Zellulose-Papier und E-Glasgewebe verstärkte Laminattafeln für bleifreie Fertigung auf der Basis von bromhaltigem Epoxidharz mit definierter Brennbarkeit (Brennprüfung mit vertikaler Prüflingslage)

Matériaux pour circuits imprimés et autres structures d'interconnexion - Partie 2-41: Matériaux de base renforcés, plaqués et non plaqués - Feuilles stratifiées renforcées en tissu de verre de type E/papier cellulose époxyde bromé, plaquées cuivre, d'inflammabilité définie (essai de combustion verticale) pour les assemblages sans plomb

La CEI 61249-2-41:2010 fournit des exigences concernant les propriétés des feuilles stratifiées renforcées en tissu de verre de type E/papier cellulose époxyde bromé, 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 d'inflammabilité sont obtenues en faisant réagir des ignifuges bromés dans la structure polymère qui font partie de la structure polymère époxyde. La température de transition vitreuse a été définie comme devant être de 100 °C au minimum.

Materiali za plošče tiskanih vezij in druge povezovalne strukture - 2-41. del: Pokovinjeni in nepokovinjeni ojačeni osnovni materiali - Z bakrom pokovinjeni laminat z določeno gorljivostjo (navpični preskus gorljivosti), ki ima jedro ojačeno z bromiranim epoksidnim celuloznim papirjem in površino s tkanim E-steklom za sestavljanje brez svinca (IEC 61249-2-41:2010)

Ta del IEC 61249 podaja zahteve za lastnosti z bakrom pokovinjenega laminata z določeno gorljivostjo (navpični preskus gorljivosti), ki ima jedro ojačeno z bromiranim epoksidnim celuloznim papirjem in površino s tkanim E-steklom za sestavljanje brez svinca, debeline med 0,60 mm in 1,70 mm. Ocena gorljivosti se doseže z uporabo bromiranih zaščitnih sredstev proti požaru, ki reagirajo kot del epoksidne polimerne strukture. Točka posteklenitve je opredeljena kot vsaj 100 °C. Nekatere zahteve za lastnosti imajo lahko več razredov zmogljivosti. Želeni razred je treba navesti na naročilnici, sicer se dobavi privzeti razred materiala.
