1. Product Overview

LOCTITE ABLESTIK ABP 8065TNP is a silver-filled BMI acrylate conductive die attach paste. It offers medium to high thermal conductivity, excellent electrical conductivity, and strong die shear strength. The material does not contain intentionally added PFAS, making it more sustainable. With its stamping and dispensing capability, it provides efficient application for bonding small die in high-reliability electronic packages. It also serves as a soft solder alternative where high thermal and electrical performance is required.


2. Applications

  • Conductive die attach for small die in semiconductor packages

  • High-reliability power devices requiring efficient heat dissipation

  • Alternative to soft solder for enhanced thermal/electrical performance

  • Compatible with Au, Ag, Cu, and AgCu leadframes
