UV-int Technical Blog

UV ultraviolet is electromagnetic radiation with wavelengths between visible light and X-rays, ranging from 100-400nm. According to different wavelengths, UV is divided into UVA(315-400nm), UVB(280-315nm), UVC(100-280nm), etc.

UV is widely used in printing curing, medical disinfection, industrial testing and other fields.

UV energy meter is a professional instrument used to measure the radiation energy of UV light sources, also known as UV joule meter or ultraviolet irradiance meter.

Mainly used for energy monitoring in UV curing processes to ensure UV coatings, adhesives and other materials receive sufficient curing energy.

UV-int dual probe UV energy meter supports automatic recognition of different spectral range probes, widely used for testing in confined spaces, such as mobile phone speakers, mobile phone motors and other precision product UV testing environments.

Specially designed for high-temperature UV curing environments, such as automotive coatings, industrial baking processes, and other applications requiring high-temperature resistance.

Material yellowing during UV curing is a common problem, main reasons include:

• Photoinitiator decomposition producing free radical residues

• Oxidation reactions causing material discoloration

• Poor quality of resins and additives

Understanding specific causes and taking appropriate measures can effectively avoid UV curing yellowing problems.

UV technology plays a crucial role in the electronics industry, particularly in:

• PCB manufacturing and curing

• Semiconductor packaging

• Display panel production

• Electronic component assembly
