优质大功率LED导电胶*285

单组份，导热系数25W/mK，适合3-5W大功率LED和模组。自动点胶机适用。

Introduction
   Die Attach Paste  ”KEMITITE *285” is epoxy resin based and solvent free T*e paste.

   The highest thermal conductivity (25W/mK)

   Good reflow performance due lower moisture absorption resin system.

   *285 is effectively used for power IC, transistor.

Features
1） Good workability for dispensing due to solvent free and one liquid t*e paste.

2） Highest thermal conductivity(25W/mK)

3） Bleed less.
