Method of manufacturing electrodes for flat heat generator

摘要

A method of manufacturing electrodes for a flat heat generator is provided for creating electrodes in an arbitrary shape on an arbitrary site of an arbitrarily shaped flat heat generator, to allow a required portion to generate heat, and to allow a heat source to move. The method includes the steps of forming a negative film for ultraviolet exposure masking from a master which has a set of electrodes for the flat heat generator designed in an arbitrary shape and at an arbitrary site, forming a thin-film member including an uncured portion of epoxy film, by irradiating the thin-film member with ultraviolet rays through masking of the negative film, dissolving the uncured portion of epoxy resin with a developing solution to form the set of electrodes, and depositing a metal on the set of electrodes through an ionization reaction within an electrolytic solution bath to from an electrodes.

1. A method of manufacturing an electrode for a flat heat generator configured to generate heat by an electric action, comprising:
a first step of forming a thin-film member coated with an insulating film for said flat heat generator by printing a thin film of epoxy resin on both sides of said flat heat generator; a second step of drying said thin-film member by heating the same; a third step of designing a set of electrodes for said flat heat generator at an arbitrary position and in an arbitrary shape to create a master, overlaying an imaging film on said master, and forming a negative film for ultraviolet exposure masking through exposure processing; a fourth step of overlaying said negative films on both sides of said thin-film member, and irradiating both sides of said thin-film member with ultraviolet rays to form a thin-film member which includes a cured portion of epoxy resin and an uncured portion of epoxy resin; a fifth step of forming the set of electrodes by immersing said thin-film member irradiated with ultraviolet rays in a developing solution for developing, and dissolving the uncured portion of epoxy resin to expose said flat heat generator; and a sixth step of connecting a metal plate serving as an anode and the developed thin-film member serving as a cathode and subjected to plating to a power source, and immersing said metal plate and said developed thin-film member in an electrolytic solution bath to deposit a metal on the set of electrodes exposed on said flat heat generator through an ionization reaction to form the electrodes.
