Frequently asked questions
What is the roller used for?
It presses the transparency or UV mask firmly and evenly onto the coated PCB before UV exposure, so no air gaps block the light.
Can it be used with any PCB coating?
It is a pressing tool and works with the UV exposure workflow. Use it with a UV-sensitive coated board and follow the exposure time given by that board's manufacturer.
