In the electronics industry, the wavelengths of LED UV curing ultraviolet lamps for component packaging with UV glue mainly
include the following:

365nm: The ultraviolet light at this wavelength has high energy and strong penetration power. It can effectively activate the photoinitiators in most UV glues. It is suitable for curing thicker glue layers or UV glues with strong viscosity, ensuring the firmness and reliability of component packaging.

385nm: Its energy and penetration ability are between 365nm and 395nm. It can be used in component packaging scenarios that have certain requirements for curing depth and speed while also needing to avoid excessive curing.

395nm: Belonging to a longer ultraviolet band, the energy is relatively low. It is suitable for low-viscosity, fast-curing UV glues and the curing of thin coatings. When handling fine electronic components for packaging, it can cure more gently and is not easy to cause excessive reactions or local overheating.

405nm: The ultraviolet light at this wavelength is relatively mild and causes less damage to materials. It is suitable for packaging components made of sensitive materials or in scenarios with low requirements for curing temperature.
