1. Product Overview

LOCTITE® ABLESTIK ABP 6395T is a silver, epoxy-based electrically conductive die attach adhesive engineered for high-reliability and high thermal conductivity in electronic packaging. It provides strong adhesion to both BSM and non-BSM dies and is compatible with a variety of metal surfaces including Ag, Cu, and PPF leadframes. Its one-component formulation ensures good workability, controlled resin bleeding, and consistent performance across small to large die sizes. The material supports high mechanical and thermal performance across standard electronic package types.


2. Applications

  • Die attach for semiconductor devices

  • Electronic adhesive for SOIC, SOP, QFP, and QFN packages

  • Bonding BSM and non-BSM dies of varying sizes

  • Applications requiring high thermal and electrical conductivity

  • Use on Ag, Cu, and PPF leadframes
