LAMINATE PLATE, METAL FOIL-CLAD LAMINATE PLATE, PRINTED-WIRING BOARD, CIRCUIT BOARD, LED BACKLIGHT UNIT, LED ILLUMINATION DEVICE, AND METHOD FOR PRODUCING LAMINATE PLATE

摘要

PROBLEM TO BE SOLVED: To provide a laminate plate with high heat-dispersing property without impairing heat resistance and drilling processability, and a method for producing the laminate plate.;SOLUTION: The laminate plate is equipped with a nonwoven layer 1 including a thermosetting resin composition which includes 80 to 400 volume parts of an inorganic filler per 100 volume parts of the thermosetting resin. The inorganic filler includes (A) gibbsite type aluminum hydroxide particles having an average particle diameter (D₅₀) of 2 to 15 m, (B) at least one inorganic component selected from the group consisting of boehmite particles having an average particle diameter (D₅₀) of 1.5 to 15 m and inorganic particles which have an average particle diameter (D₅₀) of 1.5 to 15 m and contain crystalline water having a release initiation temperature of 400C or higher or do not contain crystalline water, and (C) a fine particle component comprised of aluminum oxide particles having an average particle diameter (D₅₀) of 1.5 m or less. A mixing ratio (volume ratio) of (A) the gibbsite type aluminum hydroxide particles, (B) the inorganic component, and (C) the fine particle component is 1:0.1 to 3:0.1 to 3.;COPYRIGHT: (C)2011,JPO&INPIT
