Single/Double Sided Precision Vacuum UV Exposure Unit Model AY315 AY321 AZ210 AZ220

For the ultimate in reproduction definition, a vacuum LED UV exposure unit has to be the choice. Unlike the pressure pad units the AY/AZ series units use a vacuum to ensure that the artwork and material to be exposed are held in perfect contact with one another. When fine tracks are required on a PCB or detailed definition on a graphic reproduction, an AZ vacuum UV Exposure unit should be chosen.  Double or single sided exposure can be carried out by switching the mode on the unit. All of the AZ units now feature the latest rubber frame and glass plate vacuum system for the ultimate exposure resolution.  An adjustable selectable 0-999 seconds timer is fitted to give the operator greater flexibility.  These units are designed, manufactured and built in the UK A vacuum gauge is also fitted in the machine enabling the operator to check the level of vacuum before activating the UV LED Lamps.  A vacuum of up to -0.5 bar can be created.   All units are supplied complete with an IEC socket and moulded 13 amp plug.  The special Ultra Violet LEDs emit a wavelength of 350-400nm (UV A).  All the units feature a safety lid interlock switch, so that the UV lamps cannot be illuminated unless the lid is in the down position. A Double sided UV exposure unit is an essential tool for the production of double sided PCBs.  The ability to expose both sides of the board at once eliminates the immense problem of artwork registration for two separate exposures on a single sided unit.    These units feature a steel box with an LED panel in the base and lid.  The UV LED panel in the lid are mounted behind a flexible Mylar film and those in the base of the unit behind a sheet of glass.   When the lid is closed a vacuum chamber is made by switching the vacuum pump on giving perfect contact between the artwork and the material to be exposed.  The bottom set of LED lamps can be switched off, if only a single sided exposure is required Model Working Area* Timer UV Output Unit Dimensions Weight AY315 355 x 260mm (14.2″ x 10.24″) 0 – 999 Seconds Single Sided Unit 1 x 42 LED Panel (In Lid) 350-400nm Peak Wavelength 550 x 485 x 170 mm 15.0 kg AY321 535 x 350mm (21″ x 13.8″) 0 – 999 Seconds Double Sided 2 x 42 LED Panel (1 in Lid and 1 in Base) 350-400nm Peak Wavelength 720 x 580 x 170 mm 22.0 kg   Model Working Area* Timer UV Output Unit Dimensions Weight AZ210 355 x 260mm (14.2″ x 10.24″) 0 – 999 Seconds Single Sided Unit 2 x 42 LED Panel (In Lid) 350-400nm Peak Wavelength 550 x 485 x 170 mm 17.0 kg AZ220 535 x 350mm (21″ x 13.8″) 0 – 999 Seconds Double Sided Unit 4 x 42 LED Panel (2 x Panel In Lid and 2 x Panel in Base) 350-400nm Peak Wavelength 720 x 580 x 170 mm 25.0 kg
