1. Product Overview

LOCTITE ABLESTIK ABP 8066T is a silver, hybrid chemistry die attach adhesive engineered for high thermal and electrical conductivity. It is heat-curable, dispensable, and designed to deliver long open time, high die shear strength, and stability at elevated temperatures. The material is hydrophobic and suitable for most metals and plastics, making it an effective soft solder alternative for power devices and integrated circuits, ensuring reliable heat transfer and mechanical performance.

2. Applications

  • Die attach for integrated circuits and components

  • Metallic leadframe bonding

  • Soft solder replacement in high thermal/electrical conductivity applications
