Title:
SUBSTRATE FOR USE IN CHIP TYPE LED PACKAGE
Document Type and Number:
Japanese Patent JP2010114427
Kind Code:
A
Abstract:
To provide a substrate which has an extremely small linear expansion coefficient of an insulation layer in the surface direction thereof while having a practically sufficient heat resistance, and is excellent for use in a chip type LED package.
An electrically conductive layer 2, an insulation layer 1, and a heat-dissipation plate 3 are laminated in this order. The insulation layer 1 is formed of a liquid-crystal polyester soluble in a solvent and a sheet composed of inorganic fibers and/or organic fibers. The laminated member thus obtained is used as a substrate for a chip type LED package. Preferably, the insulation layer 1 contains an inorganic filler.
