Metal Halide UV Lamps - PCB Industry
Usually, Metal Halide Medium Pressure UV lamps are constructed from a quartz envelope that contains mercury with metal halide additives that helps create specific wavelengths of ultraviolet radiation. With the addition of metal halides, it creates a shift in the spectral output, producing longer wavelengths which as a result enable a greater depth of cure.
Over the past few years, these Metal Halide UV lamps are increasingly used in the Printing Industry and for various other industrial applications, such as the production of CD’s/DVD’s, wood products, printed circuit boards, and many more. We at Super-Cure, strive to meet the challenging requirements of Industry by supplying bespoke solution at the competitive price. We supply medium pressure UV lamps for all reprographics equipment available in the market from 400 watts upwards. However, some specific quality of the metal halide lamp can be determined by short exposure times, long service, and reliable ignition.
Gallium Iodide – this lamp is suitable for curing of white pigmented coatings as it introduces spectral lines at 400nm and 420nm of the electromagnetic spectrum. This lamp is commonly used for Better Curing of Opaque White Inks..
Iron Iodide – Iron Iodide based UV lamp enhances the spectral output between 320-400nm. This lamp is used whenever deeper penetration is required. The range of applications includes thick pigmented coatings and very thick clear coats.
Choosing the right spectral output for effective and efficient UV curing performance is vital as multi-spectrum lamps may consist of two or more additives. Using the right quality of UV lamps for specific curing requirements can improve performance across a wide range of different exposure products. To obtain the desired results in every process, each selected lamp must closely match the requirements of the photochemical process.
