Technical details and manufacturing context for UV Curing Module

Definition
The UV Curing Module is an integral part of the Automated Conformal Coating Application System, responsible for the final curing stage where ultraviolet light initiates a photochemical reaction in the applied coating, transforming it from a liquid to a solid protective film on electronic components and printed circuit boards.
Working Principle
This module emits high-intensity ultraviolet light at specific wavelengths (typically 365nm or 395nm) that activates photoinitiators within the conformal coating material. The photoinitiators absorb the UV energy, decompose into free radicals, and initiate polymerization, causing the coating to cross-link and harden within seconds.
Common Materials
Quartz glass, Aluminum alloy housing, UV LED array or mercury vapor lamp
Technical Parameters
  • Peak wavelength of UV emission, typically 365nm or 395nm for optimal curing of common conformal coatings (nm) Standard Spec
