Abstract:
1. A machine comprising: a conveyor that defines a product path disposed in a gas space, the conveyor configured to receive and convey a circuit assembly treated with a UV curable coating material along the product path; a UV zone that comprises one or more LED-based UV radiation sources and at least one passage that isolates flow of gas associated with temperature control of the LED-based UV radiation sources from flow of gas to the gas space of the product path; a heating zone; and a controller configured to control heating of a circuit assembly treated with a UV curable coating material in the heating zone to achieve a target temperature of the treated circuit assembly prior to the UV zone and configured to control a temperature associated with the one or more LED-based UV radiation sources to control wavelength of emitted UV radiation wherein the temperature associated with the one or more LED-based UV radiation sources is less than the target temperature.
