UV Exposure Units (Mega Electronics)

A double sided vacuum UV 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. The AZ units are similar to the AY range except that they have flexible mylar film in front of the tubes in the lid which closes onto a glass base beneath which is located another set of UV tubes.

For the ultimate in reproduction definition, a vacuum 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.
