The increasing capacity of digital versatile discs (DVDs) means greater complexity in manufacturing and replication. Tighter tolerances and the added requirements associated with bonding two disks introduce new considerations into the development process.
"The dispensing and curing of the bonding adhesive must be critically controlled to ensure that DVDs meet exacting manufacturing standards set by the industry," says Scott Tremblay, senior engineer at Loctite Corp. (Rocky Hill, CT). To meet these new challenges, Loctite developed light-curing adhesives for high-speed, economical DVD bonding. Once cured, these adhesives offer high-strength adhesion to a wide array of DVD substrates, as well as environmental resistance.
The single-component no-mix adhesives comprise 100% solids (no solvents) and can be formulated for easy integration into a variety of application and dispensing systems, including the standard spin coating and capillary-flow applications.
LOCTITE(reg) 3002, 3003, and 3004 adhesives are primarily for bonding 0.6-mm single-sided, single-layer (DVD-5); dual-sided, single-layer (DVD-10); and single-sided dual-layer (DVD-9) digital versatile discs. None of the adhesives requires a lacquer coating prior to bonding. In addition, the adhesives cure rapidly and form a tack-free surface at the edges. LOCTITE 3002 and 3003 are suited for high-speed spin coating, while LOCTITE 3004 is suitable for high-speed capillary flow.

In a bid to boost the viability of lithium-based electric car batteries, a team at Lawrence Berkeley National Laboratory has developed a chemistry that could possibly double an EV’s driving range while cutting its battery cost in half.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
