UV exposure units are equipment primarily used in screen printing, photopolymerization, and printed circuit board manufacturing. Their main function is to expose a surface coated with a photosensitive material to ultraviolet light, which triggers a chemical reaction in the material, allowing the creation of images or patterns.
Our UV exposure devices and vacuum frames are custom-made based on the dimensions of the frames to be irradiated with UV light. They can be compact, modular, and even removable, with adjustable light sources.
What are they for?
Serigraphy: In screen printing, UV curing is used to transfer designs onto a mesh that can then be used to print on various surfaces.
Photopolymerization: In electronic component manufacturing, UV curing is used to cure or harden resins and materials that react to UV light.
Printed circuit board production: Used to etch circuit designs onto photosensitive material.
Features of UV exposure devices
UV Light Source: Uses one or more ultraviolet lamps – such as mercury lamps or UV LEDs – that emit light at specific wavelengths to activate the photosensitive material.
Time control: Allows you to adjust the exposure time to achieve the desired result based on the type of material and design.
Exposure surface: It may have a platform where the material to be irradiated is placed, which can be made of glass or another material that allows UV light to pass through.
Vacuum system: Most of our UV exposure machines have a vacuum system to ensure uniform contact between the negative film where the design is located and the photosensitive material, avoiding air bubbles.
Size: Exposure machines come in a variety of sizes, from small for home use to large for industrial production. At UVINFRA, we manufacture our exposure machines to the specifications of each customer.
Safety controls: Many units may include safety features to protect the user from UV light exposure, such as covers or automatic shut-off systems. Contact us to know more about it.
In short, UV exposure machines are an essential tool in various manufacturing processes that require the precise transfer of images or patterns through exposure to ultraviolet light.
