1. Product Overview

LOCTITE® ABLESTIK ABP 6389 is a silver, epoxy-based, heat-curable die attach adhesive engineered for high reliability semiconductor packaging. It offers excellent thermal and electrical conductivity, low stress, and robust adhesion to Cu, Ag, and PPF leadframes, as well as to both BSM and non-BSM dies. The material supports low ON resistance (RDS(ON)) in MOSFET devices and is suitable for a wide range of package types, including SOIC, SOP, QFP, and QFN.

2. Applications

  • Die attach for semiconductor devices

  • High reliability packages for MOSFETs

  • Electronic adhesives and solder alternatives

  • Compatible with small to large dies on various metallic leadframes
