New Melbourne Electronics Event A Now Australia’s Largest with a FE World of Test and Measurement Solutions! E R TU Electronics professionals and enthusiasts alike will find the latest new technology solutions all under one roof at this month’s Electronex in Melbourne. In the fast paced world of electronics this 2-day exhibition and major conference is the best opportunity to source all the latest products, technologies and solutions. Electronex is now firmly established as the largest specialised exhibition for electronics components, equipment and supplies in Australasia. Following the success of the inaugural event in Sydney last September, Electronex this year moves to Melbourne and combines a growing dedicated show of 90+ exhibitors with a 2-day technical conference conducted by the Surface Mount & Circuit Board Association. Electronex 2011 will be open from 14-15 September at Melbourne Park Function Centre (alongside Rod Laver Tennis Arena) which is conveniently located less than 1km from the city centre, with easy access and ample parking for visitors. Electronex provides the most comprehensive and diverse showcase you will see in Australia of specialist organisations providing the latest products and services for electronic product design, development, assembly, manufacture, test, measurement, repair, systems and component supply. And with practically every major Test & Measurement Equipment supplier launching new equipment ranges at the event you will see every conceivable equipment option for your test, measurement, servicing and maintenance requirements. “Last year’s show established this event as the largest electronics forum to be staged in many years in Australia for the Australasian region,” said Noel Gray (Managing Director, AEE Pty Ltd). “This year’s Melbourne event; which has increased in size and is expected to attract even larger attendance re-affirms its continued pre-eminence and the growing support and enthusiasm for a specialised electronics industry platform showcasing local Australian & NZ based suppliers and distributors of the latest electronics technology for our market”. Attendance to the Electronex exhibition is free to all business attendees & trade visitors.

The entry level model, the ProtoMat S43, will handle drilling, depaneling and most structuring jobs. The system is also suitable for engraving housing front panels. The S63 adds convenience. The all-rounder in Rapid PCB Proto80  Silicon Chip typing, it features a paste dispenser, which applies soldering paste with absolute precision. The unit also includes a fiducial camera and a 15-position automatic tool change and automatic milling width adjustment. It is ideal for accurately machining double-sided circuit boards. The top-of-the-line ProtoMat S103 features a vacuum table and pneu- matic milling depth limiter. This extends the machining capabilities to delicate materials requiring ultimate precision as is typical in RF or microwave applications. Aside from the new S-Series ProtoMats, LPKF has introduced a low priced entry-level model, the ProtoMat E33. Embedded Logic Solutions are on stand C27 at Electronex. siliconchip.com.au RE U AT Rohde & Schwarz E F ZNB and ZNC Vector Network Analysers On display at Electronex will be two new Vector Network Analysers from Rohde & Schwarz. The R&S ZNB is a new and superior mid-range vector network analyser. It is a general-purpose instrument that is ideal for use in component production lines for mobile radio or wireless applications as well as for production repair stations. It is also tailored to general network analysis applications in development, research, education and service. The R&S ZNB is available as a two-port and four-port version for frequency ranges up to 4.5 GHz and 8.5 GHz. The state-of-the art design has a higher measurement speed, a wider dynamic range and better RF specification (including raw data) than anything currently on the market. It features a large display (16:9 aspect ratio) with touchscreen and comprehensive functionality, including soft tools and softkeys for operating convenience. Its high measurement accuracy, low trace noise and long-term stability make it ideal for challenging applications. The R&S ZNC is a low-cost version of the R&S ZNB. They look the same, but the R&S ZNC is only available as a two-port version for frequency ranges up to 3 GHz. You’ll find Rohde & Schwarz on stand C05 at Electronex 2011.

The ‘2000’ silicone resin range includes SC2001, a general potting and encapsulating compound; SC2001FD, a fast cure compound and SC2003, a thixotropic compound. The new range, which will be available to view at Electronex, adds even more choice to Electrolube’s range. The new silicone resins all have high continuous operating temperatures, making them the perfect barrier against extreme conditions. SC2001 is a two-part compound with exceptional flexibility, flame retardancy and high temperature properties (up to 200˚C), excellent for both chemical and water resistance. As a general potting and encapsulating compound, it is tipped to become one of the best all-round silicone resins available in the Electrolube range. Also newly developed is SC2001FD, the fast cure addition to the new range. The two-part compound, like SC2001, has exceptional flame retardency, flexibility, low shrinkage and high temperature but it also has a fast cure nature, particularly suitable for use in automated mixing and dispensing equipment. The third new product, SC2003, includes high thixotropy, suitable for use in applications where the operating temperature is up to 200˚C. With a 1:1 ratio, flame retardancy, excellent flexibility and both chemical and water resistance, it offers yet another dimension to Electrolube’s product range. With varying hardness, viscosity and gel time, as well as differing electrical and thermal properties, Electrolube’s impressive range of resins will form part of the products to be exhibited at Electronex this year. 100 1 95 9 100 75 1 7 95 9 75 25 7 2 5 5 25 0 2 0 5 5 0 0 EL Australia Advert 181x60mm 122010_V4 21 December 2010 14:37:30 electronics design & assembly expo Make new connections at Australia’s New Electronics Expo • See the latest in Assembly, Design, Components, Test and Repair • New technology and new products to improve your business • Australia’s only dedicated trade event for the electronics industry • Over 80 Exhibitors with the latest ideas and innovations In association with electronics design & assembly +61 3 9676expo 2133 • Plus the SMCBA Design & Manufacture Conference 2011 www.electronex.com.au Melbourne Park Function Centre 14 – 15 September 2011 82  Silicon Chip siliconchip.com.au
