In addition to inhibiting degradation of light output efficiency

Increasingly, LED manufacturers are demanding improved detection and classification of yield relevant defects of interest, which enables them to take faster corrective actions to improve their yields at higher inspection throughput. There is also a growing need to boost productivity by enabling faster production recipe creation," said Jeff Donnelly, group vice president, Growth and Emerging Markets (GEM) at KLA-Tencor. "The ICOS WI-2280 addresses critical market requirements—ultimately enabling LED manufacturers to achieve better lumens per watt and lumens per dollar performance. We remain committed to advancing our industry-leading ICOS product line to meet the LED community's emerging needs.

Dow Corning, a global leader in silicones, silicon-based technology and innovation, further expanded its industry-leading portfolio of phenyl silicone optical encapsulants with five new two-part, heat-curable grades. The new products offer enhanced reliability, better anti-silver corrosion and greater durability for LED designs. They also further underscore Dow Corning’s commitment to driving best-in-class improvements in the performance and reliability of solid-state lighting.

Delivering improved anti-silver corrosion capabilities, Dow Corning? OE-6662 and OE-6652 optical encapsulants offer Shore D 64 and Shore D 59 levels of hardness, respectively. The improved gas barrier performance exhibited by both grades helps to protect delicate silver-plated LED electrodes from sulfur attacks. In addition to inhibiting degradation of light output efficiency, this can also help extend the overall quality and lifetime of advanced LED designs.

New grades of Dow Corning OE-7620, OE-7630, OE-7640 optical encapsulants provide hardness ranges from Shore D 26, 29 and 43, respectively. The lower hardness of these materials translates into enhanced mechanical protection for emerging LED packaging designs. In addition, all three new grades in this advanced product family offer greatly improved thermal and photostability over incumbent materials, to ensure consistent high optical quality over the lifetime of an LED light source.
