标准摘要
[中文适用范围]： 本部分IEC 61249规定了预浸料（prepreg）的性能要求，主要用于根据IEC 61249-2-37标准制造层压板，并用于根据IEC 62326-4标准制造多层印制电路板。由这些材料组成的多层板适用于无铅组装工艺。该材料也可用于粘合其他类型的层压板。根据本标准的预浸料具有定义的阻燃性（垂直燃烧测试）。通过在使用聚合物结构中的非卤素阻燃剂，实现完全固化预浸料的阻燃等级。根据供应商的说明固化预浸料后，玻璃化转变温度定义为150°C和200°C。 [外文原描述]： IEC 61249-4-16:2009 gives requirements for properties of prepreg that are mainly intended to be used as bonding sheets in connection with laminates according IEC 61249-2-37 when manufacturing multilayer boards according to IEC 62326-4. Multilayer boards comprised of these materials are suitable for lead-free assembly processes. This material may also be used to bond other types of laminates. Prepreg according to this standard is of defined flammability (vertical burning test). The flammability rating on fully cured prepreg is achieved through the use of non-halogenated flame retardants contained as an integral part of the polymeric structure. After curing of the prepreg according to the supplier's instructions, the glass transition temperature is defined to be 150 °C and 200 °C.
