1. Product Overview

LOCTITE ABLESTIK ABP 8910T is a blue, electrically insulating die attach adhesive based on BMI hybrid technology with alumina filler. It features high thermal reliability (MRT performance), good thermal conductivity, and medium modulus for robust mechanical performance. Designed for medium to large die sizes, it delivers high reliability and consistent adhesion across various substrates. The adhesive is heat-curable with a recommended cure profile of 30-minute ramp to 175°C plus 15 minutes at 175°C.


2. Applications

  • Die attach for medium to large semiconductor dies

  • Adhesion on substrates such as Copper, Silver, PPF, and Alloy 42

  • High-reliability electronic assemblies requiring thermal management

  • Applications requiring controlled bondline thickness and minimal warpage
