Epoxy Silver Paste for MLCC

Epoxy silver paste is primarily used in the fabrication of flexible terminations for multilayer ceramic capacitors (MLCCs). Formulated with finely dispersed silver particles and a robust epoxy binder, it delivers excellent silver layer density, high conductivity, and stable curing behavior. The cured film exhibits strong bending resistance and exceptional interlayer adhesion, effectively preventing cracking or delamination during device flexing, handling, or assembly. In addition, its superior printability and compatibility with flexible substrates make it well suited for printing high-precision flexible thin-film circuits, supporting the reliability and miniaturization needs of advanced electronic components.
