» PCB & ASSEMBLY Not only does hotmelt molding create a housing structure, but it also protects the assembly Source: Werner Wirth Zusammenfassung Für Elektronik, die täglich unterschiedlichen Witterungsverhältnissen unterliegt, eignet sich Komponentenschutz mit Hotmelt Moulding, bei dem in einem Arbeitsschritt die Baugruppe mit einem Material umhüllt wird und so zum Schutz eine Gehäusestruktur entsteht. At Werner Wirth, the right equipment is available for every application. There is an extensive machine program, from stand-alone systems to in-line systems. Tank systems, extruder technology and drum melters are available for processing the material. www.wernerwirth.de Résumé La protection du composant avec enduction sous fusion (Hotmelt molding) enrobant le module électronique avec un matériau en une seule étape et créant une enveloppe de protection, est parfaitement adaptée pour les composants électroniques qui sont soumis quotidiennement à des conditions météorologiques diverses. Резюме Для электроники, которая ежедневно подвергается воздействию различных погодных условий, подходит защита компонентов с помощью термоплавких материалов. При этом узел в один этап покрывается материалом, формирующим структуру защитного корпуса. The right equipment must be used to correctly process material, including tank systems, extruder technology and drum melters Source: Werner Wirth 66 EPPEurope » 04|2021
Product Updates « PCB & ASSEMBLY Robotic and laser soldering Flux-cored wire for low-spatter performance Indium Corporation is now offering CW-232, a uniquely formulated flux-cored wire that combines superior wetting speed and spread with extremely low-spatter performance. The company’s CW-232 is a highly activated rosin flux-cored wire developed to meet the demanding requirements of robotic and laser soldering applications by delivering additional wetting power in order to achieve higher throughput. CW-232 also works exceptionally well in hand soldering applications. Due to its “no-spatter” technology, it eliminates flux spattering that can burn operators’ hands, impair the vision system of the robotic soldering machines, or make finished products less aesthetically appealing. The flux-cored wire offers: • Extremely low-spatter performance • Very fast wetting, even capable of soldering to heavily tarnished surfaces • Light-colored residue • Compatible with Pb-free and SnPb alloys • Compatible with HASL, Immersion Silver, ENIG, and OSP surface finishes www.indium.com Source: Indium Corporation The CW-232 flux-cored wire delivers additional wetting power to achieve higher throughput LED assembly partnership Relying on high-speed inline mounters Yamaha Robotics SMT Section is a trusted supplier of surface-mount assembly solutions, with six generations of highspeed precision mounters in action on the RSG Elotech production lines. The company is a manufacturer of advanced energy-saving technologies such as high-efficiency LED lighting. Placing the 2.3 million surface-mount components that are handled on the nine highly automated production lines every day demands high speed, high accuracy, and high reliability. The connection with Yamaha Robotics is long established. In fact, there are currently six generations of their inline mounters serving the production lines at the factory in Bad Lobenstein. Early machines, from the YV and YV II series, continue to deliver high productivity and are working alongside the latest YS and highspeed modular YSM machines. “We have 24 Yamaha mounters in action right now,” confirms Frank Lauterbach. The current portfolio of the company’s mounters offers scalability from the onebeam/one-head YSM10R to the Z:TAR YSM40R, which combines four beams and four heads with advanced motion control and high-speed cameras giving the ability to place up to 200,000 cph. The simplified Auto-Loading Feeders (ALF) and the nonstop feeder-carriage exchange system are easy to use and save time at changeovers, and the Auto Tray Sequencer (ATS) boosts productivity by enabling non-stop loading of components in trays. The Factory Tools 4.0 software suite helps owners to setup and program the machines and monitor performance. The latest version includes the Dashboard, which embeds data-analytics know-how from Tableau Software to show performance graphically and assist with continuous improvement. Live production analytics let users manage their lines in realtime, while historical analysis tools help visualise metrics such as downtime, setup time, pickup errors, and stoppages. Both companies extended their co-operation even further by engineering a special SMT line taking advantage of YS12/YS12F mounters to handle PCBs up to 1800 mm long. Conceived to assemble large arrays of surface-mount LEDs, this line strengthens the company’s position in energy-saving lighting and buildingautomation markets by enabling high Source: Yamaha productivity and fast turnaround times. “Our engineering group worked with the team at RSG Elotech to create solutions for board transport and indexing,” explains Ralf Bierschenk, Chief Engineer. “In addition, we integrated Yamaha’s automated BIN-code management software to assist with programming. It simplifies the complex challenge of correcting for differences in LED brightness and helps the production team manage their inventory of LEDs efficiently.” www.yamaha-motor-im.eu The large feeder capacity of the company’s mounters enhances flexibility and efficiency EPPEurope » 04|2021 67
