www.us-tech.com Dow Corning Introduces Optical Encapsulants for LEDs
Midland, MI — Dow Corning® has expanded its 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 de- manding LED designs. Delivering improved anti-silver corrosion capa-
bilities, the OE-6662 and OE-6652 optical encapsu- lants offer Shore D 64 and Shore D 59 levels of hard- ness, respectively. The improved gas barrier per- formance exhibited by both grades helps to protect delicate silver-plated LED electrodes from sulfur at- tacks. In addition to inhibiting degradation of light output efficiency, this can also help extend the over- all quality and lifetime of advanced LED designs.
New grades of Dow Corning OE-7620, OE- 7630, OE-7640 optical encapsulants provide hard-
ness ranges from Shore D 26, 29 and 43, respective- ly. 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 incum- bent materials, to ensure consistent high optical quality over the lifetime of an LED light source. According to the company, as next-generation
Hard-shell protection for LEDs. Production needs us.
LED designs and applications grow ever more de- manding, global lighting OEMs are seeking innova- tive new material solutions that can withstand the higher internal temperatures of new LEDs, as well as their increasingly harsh operating conditions. These latest additions to Dow Corning’s broad port- folio of optical silicone encapsulants for LEDs deliver the performance and protection necessary to enable ad- vanced lighting designs that provide reliable, high-quality illumination over the course of their expected life- times.

Mercury™ contactor. The triple edge tip geometry of
the Q-tip design improves probe to DUT pad alignment targeting, espe- cially over all ranges of temperature testing. Improved targeting means more reliable contact and higher first pass yields. The Mercury Q-tip reportedly
