Introduction
   Die Attach Paste  ”KEMITITE CT285” is epoxy resin based and solvent free Type paste.
   The highest thermal conductivity (25W/mK)
   Good reflow performance due lower moisture absorption resin system.
   CT285 is effectively used for power IC, transistor.
Features
1） Good workability for dispensing due to solvent free and one liquid type paste.
2） Highest thermal conductivity(25W/mK)
3） Bleed less.
