JELIGHT COMPANY

The UVO method is a photo-sensitized oxidation process in which the contaminant molecules of photo resists, resins, human skin oils, cleaning solvent residues, silicone oils, and flux are excited and/or dissociated by the absorption of short-wavelength UV radiation. Atomic oxygen is simultaneously generated when molecular oxygen is dissociated by 184.9 nm and ozone by 253.7 nm uv. The 253.7 nm UV radiation is absorbed by most hydrocarbons and also by ozone. The products of this excitation of contaminant molecules react with atomic oxygen to form simpler, volatile molecules which desorbs from the surface. Therefore, when both UV wavelengths are present atomic oxygen is continuously generated, and ozone is continually formed and destroyed. By placing properly pre-cleaned samples within five millimeters of ozone producing UV source, such as the low pressure mercury vapor grid lamp in the UVO-Cleaner ®, near atomically clean surfaces can be achieved in less than one minute.

elight Company, Inc. designs, manufactures, and internationally distributes a wide range of high-quality special replacement mercury, gallium, iron and other metal halide bulbs. Also known as ultraviolet curing, drying, or graphics arts lamps. Medium pressure bulbs are used to cure inks and adhesives quickly and consistently. Ultraviolet curing uses less energy than conventional drying methods, and minimizes VOC emissions. We are supplier of quality direct replacement for series of printing equipment and uv ovens ncluding Gallus, Mark Andy, GEW, IST, Brewer, and more. Applications: Adhesive setting CD & DVD curing Exposure Equipment Graphics Arts Printing Inkjet Systems Label Printing Photochemical Lamps & Wells Portable Curing Equipment Printed Circuit Boards Roller Coaters Screen Printing
