LOCTITE® ABLESTIK ATB F125E
Features and Benefits
This white, highly reliable, epoxy-based adhesive film can be used for die-attach applications.
LOCTITE® ABLESTIK ATB F125E is a white, high-reliability epoxy adhesive film with a thickness of 25μm. It is typically used for die attach in discrete, IC, and chip stack packages. It’s ideal for wafer lamination processes or as a preform decal, where it shows excellent workability and provides consistent dicing and die pickup for small die applications.
