UV LED curing systems deliver narrow bandwidth, high intensity UV light for low heat, rapid curing of optically-activated materials. Although LED curing systems do not deliver unwanted IR or visible light, some UV-absorbing substrates may still experience heating damage. This white paper demonstrates a novel method to reduce heat damage in UV-absorbing substrates by driving UV LED systems to deliver short, high-intensity pulses of light, resulting in higher throughput with increased yields.
