RESIN DERIVATIVE COMPOSITION AND ELECTRONIC PACKAGE BY USE THEREOF

摘要

PROBLEM TO BE SOLVED: To obtain a composition useful for a dielectric layer of a circuit plate by containing a resin material, a coloring agent and a fluorescent agent. SOLUTION: A resin derivative composition is comprised of containing: preferably about 78-about 98 wt.% of a resin material selected preferably from epoxy, cyanate and bismaleimide resins; preferably about 0.01-about 10 wt.% of a coloring agent selected from an organic dye, an organic pigment and an inorganic pigment; and preferably about 0.01-about 12 wt.% of a fluorescent agent as an ultraviolet absorption compound preferably containing the ultraviolet absorption compound to strengthen a fluorescent characteristic. An epoxy contains preferably an epoxy polymer resin including an epoxide derived from a monocyclic and polycyclic divalent phenol; and a cyanate contains preferably a polyfunctional cyanate ester monomer of the formula: R-(OCN)m (wherein m is 2-5; R is an aromatic organic group and NCO is bonded to an aromatic ring) or its polymer. A defect of a circuit can be inspected optically and accurately by applying a dielectric layer containing this composition to the circuit plate.
