communications engineering, as well as for maximum frequency electronics and power electronics. Since 2010, the CSW has combined the two most important conferences on compound semiconductors – the “International Symposium on Compound Semiconductors (ISCS)” and the “International Conference on Indium Phosphide and Related Materials (IPRM)”.


“Berlin is the ideal location for hosting the CSW thanks to its broad-based research activities in this field,” said Norbert Grote, Chairman of this year’s IPRM and head of department at the Fraunhofer HHI. “Some 450 scientists from all over the world will come to Berlin to exchange their knowledge. This gives us the opportunity to further strengthen the location and to promote these issues.”


Fraunhofer HHI and Fraunhofer IAF are both leading research institutes in the field of compound semiconductors. In Berlin, it is not only institutes and universities such as the Fraunhofer HHI, the Ferdinand Braun Institute, the Paul Drude Institut für Festkörperelektronik, the Institut für Kristallzüchtung, Humboldt- und Technische Universität, as well as the Helmholtz Zentrum, which are active in this field, but also companies like the u2t Photonics AG, a spin-off from Fraunhofer HHI. “When making a phone-call in the US, your chances of the optical components involved having been made in Berlin are pretty good,” said Norbert Grote.


Nordson honoured for technology innovation with 2 awards


The firm’s jet dispenser for side-view LED manufacturing won the SMT China magazine and EM Asia magazine awards.


Nordson ASYMTEK, an innovator in dispensing, coating, and jetting technologies, earned two prestigious awards for innovative technology during NEPCON China 2011.


Both the VISION Award from SMT China magazine and the Innovation Award from Electronics Manufacturing (EM) Asia magazine were presented to Nordson ASYMTEK for product excellence in the

dispensing category for its jet dispenser for side- view LED manufacturing.


This was the fifth year in a row that Nordson ASYMTEK received the SMT China award and the fifth time they received the EM Asia award.


Nordson ASYMTEK’s jet dispenser enables sticky silicon phosphor to be dispensed into extremely small and hard-to-reach cavities for side-view LEDs. Silicone phosphor dispensing is critical for LED colour quality.


The system uses a jet for non-contact dispensing, jetting 0.1 to 0.2mm dots through windows as small as 0.4mm into LED cavities. Unlike a needle, the jet retracts much less for silicone break-off, dispensing multiple shots faster, increasing speed and throughput. The jet’s small, controlled drops of fluid reach tight cavities consistently and reliably, unlike needles which have orifices larger than the cavity windows of side-view LEDs.


The SMT China VISION Award honours achievements in China’s electronics manufacturing industry. Awards are based on the creativeness and innovativeness of the product and its contribution in helping the downstream industries to reduce cost, improve quality, increase efficiency, enhance reliability, improve safety, and environmental friendliness.


The EM Asia Innovation Award recognises top performing companies in the Asian electronics industry for achieving the highest standards for products, materials, and equipment introduced and offered for sale in Asia. Entries were judged on innovation and achievement and for setting challenging objectives.


“We are honoured to receive these two awards,” said Frank Wang, Nordson ASYMTEK’s general manager, Greater China. “Nordson ASYMTEK has been recognised as the leader in dispensing and coating innovation and technology for over 25 years. We have grown with our customers to develop equipment and processes to enable them to produce many of the products we rely on today. Our patented jet dispensing technology for LEDs has helped our customers reduce process variation, increase yield, and reduce cost. We will continue to serve our customers throughout China and Asia with quality products and provide the very best
