The Model 3000 is an extremely well proven single drawer, double sided Ultra Violet exposure unit, designed with medium volume production in mind. This unit is ideal for fast primary imaging on dry film resists. It is also suitable for those users that require occasionally to expose liquid photo-imagable solder masks without the expense of a dedicated unit.
All the main functions of the Model 3000 UV Exposure Unit are controlled by a dedicated microprocessor with all variables and options such as exposure, vacuum delays and vacuum modes being held in each of its seven memories.
Ultra Violet Exposures are controlled by the inbuilt light integrator system which accurately measures the amount of UV energy available ensuring repeatable exposures throughout the life of the lamps.
The specially designed lamps have a major peak of energy at 365nm which closely matches the spectral response of the majority of dry film and liquid resists currently available. The energy output of this lamp can also be determined with three switched preset levels, allowing excellent control of exposure.
As standard, the Model 3000 has a well proven low profile vacuum frame which includes a specially designed hard wearing moulded seal. This facilitates very quick changing of the polyester sheet and a fast evacuation of the vacuum drawer. The system also helps to eliminate upper photo tool shift.
In addition full or soft vacuum can be selected within each memory and a variable vacuum delay can be entered to ensure the vacuum is stable before the exposure commences. The Model 3000 is a well proven exposure unit with a fast and accurate capability. Engineered to last and with ease of maintenance in mind, the Model 3000 will give many years of reliable hard work.
