PRODUCT SHOWCASE Electronex 2026 in Sydney: Rosehill Gardens Event Centre, 3rd & 4th June Following the outstanding success of last May’s Electronex Electronics Design and Assembly Expo held in Melbourne, Electronex 2026 Sydney has generated a strong response, with over 85% of exhibition space already booked. The 2026 Expo will take place at Rosehill Gardens Event Centre, Sydney, on the 3rd and 4th of June 2026, in conjunction with the annual Surface Mount and Circuit Board Association (SMCBA) conference. The Melbourne show, staged alongside National Manufacturing Week (NMW), attracted a record number of engineers, managers and senior decision-­makers from across the manufacturing and electronics industries. With 85 stands representing more than 100 companies, it was the largest Electronex held to date. More than 250 exhibiting staff also took part in valuable networking opportunities, including the popular Exhibitor Networking Function. Visitor numbers were around 15% higher than Electronex 2023 (the last time it was held in Melbourne), and exhibitors were delighted with the quality of enquiries. Face-to-face contact remains invaluable for discussing technical requirements and discovering new technologies in this vital high-tech manufacturing sector. 10 Silicon Chip Electronex is now in its 14th year and firmly established as Australia’s premier event for the electronics industry. Strong visitor engagement & industry support The Melbourne Expo drew around 2000 trade visitors from all Australian states and New Zealand, reflecting the show’s national reach. The concurrent Surface Mount and Circuit Board conference featured a stellar lineup of local and international speakers, offering deep insights into current and emerging technologies. A post-show visitor survey reinforced the event’s value. 75% of attendees were directly involved in purchasing, specifying, or recommending products. 93% discovered new companies, while 85% discovered new products or technologies. 97% said that a dedicated event such as Electronex is beneficial to their industry. Notably, 56% were first-time visitors, and many long-term exhibitors reported that it was one of the most successful events they had attended. Competitions and technical highlights The free on-floor seminars were also well attended, giving exhibitors a platform to present the latest innovations Australia's electronics magazine Australasian Exhibitions and Events Pty Ltd Tel: (03) 9676 2133 mail: info<at>auexhibitions.com.au Web: www.electronex.com.au and solutions. The SMCBA, Australia’s association for electronics design and assembly professionals, with support from IPC International, also conducted the Australian rounds of the IPC Hand Soldering Competition and the inaugural IPC/WHMA Wire Harness Competition. In a closely contested HSC, Tony Cimino from the Australian Centre for Robotics took first place, ahead of Rodney Tacey from Bluefish444. Tony received a JBC B-Iron Soldering Station and an invitation to compete in the World Finals in Munich, Germany. The Wire Harness Competition winner was Sai Praneeth Jasti from Design 2000, with Tony Cimino taking runnerup honours. Join us at Electronex 2026 With almost all the exhibition space already sold, companies interested in participating in Electronex 2026 Sydney who haven’t already booked are encouraged to secure their stands as soon as possible. siliconchip.com.au
