あるという問題が発生していた。Furthermore, in the case of the heat curing type, as described above, curing is required at high temperature for a long time, so there is a disadvantage that the heat resistance of the electronic components used needs to be increased and the production time becomes long. In addition, in the case of the solvent volatilization type and the ultraviolet curing type, the resin composition that has entered the space between the electronic component and the board is difficult to volatilize in the former case, and in the latter case, the resin composition is exposed to ultraviolet rays. Since the electronic components were in the shadow and no irradiation was performed, they were in an uncured state. Therefore, 6
There is a problem with moisture-proof insulation that deterioration of insulation resistance occurs in a high temperature and high humidity environment of 0°C - 90%.As a resin that should solve these problems of ultraviolet curing type, the present applicant has developed a special resin. No. 59-234420 discloses a base bright resin i made of ultraviolet curable epoxy acrylate resin.
