ABSTRACT:
A casting resin compound as an assembly and encapsulation material for electronic and optoelectronic component parts, modules and components, for example for casting out optoelectronic components on the basis of acid anhydride-curable epoxy compounds, particularly bisphenol A-diglycidyl ether, contains multi-functional epoxy novolak resins, particularly an epoxy cresol novolak. This casting resin compound exhibits a clearly increased glass transition temperature, is suitable for mass-production, exhibits no health deteriorations, and supplies SMT-capable products that can be utilized in the automotive sector.
