Patent number: 10619074Abstract: A curing process of an ultraviolet curable paint by which a paint cured layer can be formed on an object to be processed without needing a long time, and intended color can be obtained of the object to be processed on which the paint cured layer is formed. The curing process of an ultraviolet curable paint is one for curing an ultraviolet curable paint through an ultraviolet irradiation step of irradiating a surface of an object to be processed to which the ultraviolet curable paint is applied with ultraviolet rays from an ultraviolet radiation unit. The ultraviolet curable paint is not sensitive to light of not less than 380 nm in wavelength but sensitive to light of less than 380 nm in wavelength. The ultraviolet radiation unit radiates ultraviolet rays having a peak wavelength within a range of not greater than 350 nm in wavelength.Type: GrantFiled: August 22, 2016Date of Patent: April 14, 2020Assignee: Ushio Denki Kabushiki KaishaInventors: Fumitoshi Takemoto, Makoto Wasamoto, Shinji Suzuki

Patent number: 10420221Abstract: A desmear treatment method for a wiring board material is provide that is capable of performing desmear treating on the interior of a through hole formed in an insulating layer without requiring complicated steps and obtaining an insulating layer having appropriate surface roughness. The desmear treatment method comprises forming a hole passing through an insulating layer, wherein the insulating layer is made of a resin containing a filler, and desmear treating the wiring board material with radicals. The wiring board material includes a depletable resist layer formed on the insulating layer, and the depletable resist layer is made of a resin to be depleted in the desmear treatment step. A method of manufacturing a wiring board material to be subjected to the desmear treatment method and a composite insulating layer forming material used in the manufacturing method are also disclosed.Type: GrantFiled: November 21, 2014Date of Patent: September 17, 2019Assignee: Ushio Denki Kabushiki KaishaInventors: Kenichi Hirose, Makoto Wasamoto, Shinichi Endo
