Other UV-based systems require mechanical shutters. Mercury must be disposed of correctly at the end of the curing lamp's life. Larger amounts of expensive photo-initiators are used. Photo-initiators, the additives needed to start a chain reaction that results in the actual cure process, are activated when exposed to the correct wavelengths of light. And lamp changes are required to alter the spectrum.
Process control can be limited and thick materials difficult to penetrate.
Pulsed-UV systems offer high peak power with control of cures at a low average power, low temperatures and in little time. Pulsed-UV gives an assembler deep, complete cures and instantaneous results. Because heat is controlled, there is far less potential for damage to the product within the process than with continuous-wave UV curing. No blowers are required to reduce air temperature. There is no need for nitrogen, shutters or other protective equipment.
