The selling price of Sapphire substrates to be up US$30 in 4Q10 due to Supply disconnected

Following the contuse lacing of Sapphire substrates, some LED manufactures thought its price would be over US$30 in 4Q10, so they start making purchase on Sapphire substrates with cash. In Q1 of 2010, 2-inch sapphire substrates offering price was not enough US$15, but up straightly to US$25-30 in Q 3, and recently has been to US$30-35. To prevent idle production lines, some LED chipmakers had to begun price negotiation for Q4, while Some LED chipmakers had halted production lines and moved back delivery of MOCVD machines.

Dow Corning Electronics Announces New Silicone Encapsulant for Overmolding Process

Today Dow Corning Corporation’s Electronics group introduced its newest silicone encapsulant, Dow Corning ®OE-6636, designed for overmolding (compression molding) and dispensing processes. The product provides for a high refractive index (RI) of 1.54 which enables better light output (see Appendix 1, below), has a low moisture uptake, improves thermal aging  and light resistance, and possesses better adhesion to typical substrate for LED packages such as Poly Phthal Amid.
