Title:
INSULATING MATERIAL, PROCESS FOR PRODUCING ELECTRONIC PART/DEVICE, AND ELECTRONIC PART/DEVICE
Document Type and Number:
WIPO Patent Application WO/2007/129662
Kind Code:
A1
Abstract:
An insulating material giving a cured object which is less apt to suffer dielectric
breakdown and excellent in resistance to thermal cycling and high-temperature
standing resistance; an electronic part/device; and a process for producing
the part/device. The insulating material comprises a curable compound (a),
a hardener (b), a high-molecular polymer having an aromatic skeleton, and an
inorganic filler (e) in specific proportions, wherein the curable compound
(a) is either a curable compound having two or more epoxy groups per molecule and
a polycyclic aromatic hydrocarbon skeleton (a1) as at least part of the main chain
or a curable compound having two or more epoxy groups per molecule and, as at least
part of the main chain, a skeleton (a2) comprising two or more aromatic rings directly
bonded through a single bond and the proportion of the skeleton (a1) or skeleton
(a2) in all skeletons of the curable compound (a) is 30 wt.% or higher. The electronic
part/device (1) has an insulating layer (4) formed from the insulating material.
