Abstract
Thermal management plays an important role in the manufacturing of CDs and DVDs. Heat buildup on substrates needs to be kept at the lowest possible level. The magnitude of the problem increases with the productions of DVDs. The bonding process requires light penetrating through a substrate. Deep penetration and low temperature have long been a benefit of pulsed UV/Visible curing. After listing the reasons why pulsed UV/Visible curing penetrates opaque substrates with little or no heat build this paper outlines the optimization of the method for matching the pulsed light with substrates and curing formulations. The three most critical components of a DVD bonding production system are spectrum, peak power, and pulse duration. The “tuning” of these critical variables plays an important role in the matching process.
