Estimating the term…
A film for an electronic substrate according to an embodiment has a moisture-absorption rate of less than 0.3% of the initial weight when immersed in water for 24 hours, and thus is less susceptible than existing films for electronic substrates are to changes in dimension or degradation in electrical characteristics caused by containing moisture according to changes in temperature and humidity. Also, the film for an electronic substrate is equal or superior to existing films in terms of flexibility and physicochemical characteristics, and thus may be applied to the manufacture of laminates with a conductive film such as FCCL and electronic substrates such as FPCB to improve processability, durability, transmission capacity, etc.
A film for an electronic board, which comprises a polyester resin in which a diol comprising 1,4-cyclohexanedimethanol and an aromatic dicarboxylic acid are polymerized, wherein the film has a moisture absorption rate of less than 0.3% relative to the initial weight when immersed in water at room temperature for 24 hours.
A laminate for an electronic board, which comprises a substrate layer and a conductive layer disposed on at least one side of the substrate layer, wherein the substrate layer comprises a polyester resin in which a diol comprising 1,4-cyclohexanedimethanol and an aromatic dicarboxylic acid are polymerized, and the substrate layer has a moisture absorption rate of less than 0.3% relative to the initial weight when immersed in water at room temperature for 24 hours.
An electronic board, which comprises a substrate layer and a conductive pattern layer disposed on at least one side of the substrate layer, wherein the substrate layer comprises a polyester resin in which a diol comprising 1,4-cyclohexanedimethanol and an aromatic dicarboxylic acid are polymerized, and the substrate layer has a moisture absorption rate of less than 0.3% relative to the initial weight when immersed in water at room temperature for 24 hours.
