For the ultimate in reproduction definition, a vacuum UV Exposure unit has to be the choice. Unlike the pressure pad units the AY series use a vacuum to ensure the artwork and material to be exposed are held in perfect contact. When fine tracks are required on a PCB or detailed definition on a graphic reproduction, an AY vacuum unit should be chosen. All the AY units now feature the latest rubber blanket and glass vacuum system for the ultimate exposure resolution. An adjustable selectable 0-600 seconds or 0-100 minutes is fitted to give the operator greater flexibility the vacuum pump activation and bleed is controlled by separate switches independent of the timer. A vacuum gauge is also fitted in the machine enabling the operator to check the level of vacuum before activating the UV tubes. All units come complete with an IEC socket and moulded 13 amp plug.
These units have UV tubes with an emission peak of 350-400nm
