For the ultimate in reproduction definition, a vacuum UV exposure unit has to be the choice. Unlike other pressure pad units the FORTEX series of exposure units uses a vacuum to ensure the artwork and material to be exposed are held in perfect contact. This makes these UV Exposure units suitable for the processing of UV sensitive flexible materials.
When fine tracks are required on a PCB or detailed definition on a graphic reproduction, a vacuum UV Exposure unit should be chosen. A popular use for these precision UV exposure units is for the exposure of artworks Photo tools for the production of Microfluidic devices in combination with Chips/wafers etc . The 0 – 999 second digital timer is then set via the touch membrane control panel and the start button pressed, this activates the integral vacuum pump, which removes the air from the chamber ensuring perfect contact between artwork and material to be exposed. Only when a vacuum has been achieved will the tubes activate and the exposure commence. When completed the vacuum pump is turned off and a valve automatically releases the vacuum allowing the lid to be raised. These units are manufactured from aluminium, but due to its larger size case the largest unit ( AY 380 ) is made of steel. All units come complete with an IEC socket and moulded 13-amp plug.
These units have UV tubes with an emission peak of 360-365nm
