INSULATION MATERIAL FOR ELECTRONIC DEVICE

摘要

The present invention relates to insulating material for an electronic device that may inhibit damage to electronic devices by a high temperature curing process, and simultaneously contribute to improvement in reliability of electronic devices. The insulating material for an electronic device comprises soluble polyimide resin comprising a specific repeat unit, and a residual solvent comprising a low boiling point solvent having boiling point of 130 to 180°C, wherein after curing at a temperature of 250°C or less, the amount of outgassing is 4 ppm or less based on total weight of the soluble polyimide resin, and the amount of outgassing derived from water or alcohol is less than 0.1 ppm.
