SUBSTRATE FOR ILLUMINATION AND SUBSTRATE HAVING GOOD HEAT RADIATION PROPERTY COMPRISING A HYBRID LAYER

摘要

PURPOSE: A heat emitting substrate and an illuminating substrate with a hybrid layer are provided to be miniaturized by applying thermoplastic polymer liquid crystal polymer resin to form the hybrid layer. CONSTITUTION: A hybrid layer(300) comprises thermoplastic polymer and conductive filler. An insulating layer(500) is laminated on the upper side of the hybrid layer. A metal layer(700) is formed on the upper side of the insulating layer. The insulating layer comprises the thermoplastic polymer and thermally conductive ceramic filler. Via connects the metal layer and the hybrid layer.
