LOCTITE® ABLESTIK QMI505MT

Features and Benefits

LOCTITE ABLESTIK QMI505MT, Rubberized epoxy, Die attach
LOCTITE® ABLESTIK QMI505MT die attach paste is designed for attachment of integrated circuits and components to advanced metal and ceramic surfaces. A package or device manufactured with LOCTITE ABLESTIK QMI505MT will have good resistance to delamination and “popcorning” after exposure to reflow temperatures. Please refer to the TDS for alternate cure schedules.
