Effects of UV Curing Energy on Unprotected Areas of a PCB

Q: Will exposing areas of a printed circuit board (not covered by an adhesive or conformal coating) to UV-curing energy, damage the PCB in anyway?

A: Any frequency of energy that gets impinged onto a substrate has two options: it can get reflected, in which case it is harmless, or it can get absorbed, in which case it will turn into heat. Some light-curing equipment, like the Dymax BlueWave® 200 version 3.0 spot lamp, have an intensity adjustment feature which allows for the ability to reduce unneeded energy. Adjusting the intensity reduces any excess energy that may turn into heat and damage temperature-sensitive substrates.
