nation of properties for integration in established electrical printed circuit board technology. In addition, the ma- terial can be fabricated into wave- guides using conventional manufac- turing techniques available today. “Dow Corning’s breakthrough
polymer waveguide silicone has posi- tioned us at the forefront of a new era in robust, data-rich computing, espe- cially as we continue to collaborate with outstanding industry leaders like IBM,” said Eric Peeters, vice president, Dow Corning Electronic Solutions. “Optical waveguides made from Dow Corning’s silicone polymer technology offer customers revolu- tionary new options for transmitting data substantially faster, and with lower heat and energy consumption. We are confident that silicone-based board-level interconnects will quickly supersede conventional electronic signal distribution to deliver the amazing speeds needed for tomor- row’s supercomputers.”
tronic materials group to integrate products and technologies acquired from Spraylat Corporation, Mt. Ver- non, N.Y., in December 2012. PPG now offers a full line of elec-
trically conductive, resistive, and di- electric inks and conductive coatings for radio-frequency interference/elec- tromagnetic interference (RFI/EMI) suppression. These inks and coatings are used in diverse applications such as touch-control panels for smart- phones, tablets and other consumer de-
vices; interactive and electrochromic displays; biomedical sensors; printed keypads and other industrial mem- brane switch controls; radio-frequency identification (RFID) tags; and other products that require printed circuitry. Conductive polymer thick film
(PTF) inks, which are typically for- mulated with a metallic flake or pow- der to carry a charge and bound with a thermoplastic resin, can be printed on polymer-based film, polycarbon- ate, paper and other substrates.
PTF inks are compatible with
most printing methods, from flatbed and rotary-screen printing and flex- ography to rotogravure, as well as tampo (pad) and inkjet printing. Cre- ating the new group is intended to provide better choices for printed electronic materials. Contact: PPG Industrial Coat-

A presentation — “Stable and
Easily Processable Optical Silicones for Low-Loss Polymer Waveguides” — given at the Photonics West Confer- ence by Brandon Swatowski, applica- tion engineer for Dow Corning Elec- tronics Solutions, reported that fabri- cation of full waveguide builds can be completed in less than 45 minutes, and enable a high degree of process flexibility. Silicone polymer material, which is dispensed as a liquid, processes more quickly than competi- tive waveguide materials such as glass and does not require a con- trolled atmosphere chamber. Swatowski’s presentation went
on to say that waveguide builds based on the silicone polymer showed excellent adhesion to polyimide sub- strates. It also discussed how optical characterization of the new polymer waveguide silicones showed losses as low as 0.03dB/cm, with environmen- tal stability extending past 2,000 hours exposure to high humidity and temperature, and good performance sustained over 500 thermal cycles be- tween –40 and +120°C.
