Vakuum Production and Dispensing - 1

SCHEUGENPFLUG AG METERING AND DISPENSING TECHNOLOGY Vacuum Production and Dispensing Demanding requirements – The requirements for electronic components are rapidly increasing in many aspects. For safety-relevant components or components with a wide scope of functions, vacuum dispensing is the process of choice to achieve the required component reliability. For components with undercuts or small cavities that must be filled, or for the ever smaller components resulting from miniaturisation, vacuum dispensing is increasingly the only option. Many electronic components today have a wider range of functions and must fulfil stringent reliability requirements. Once installed, they are usually difficult to replace. Often they are not even meant to be replaceable and are designed to perform their function throughout the product’s entire lifespan. And with advancing component miniaturisation, these issues are becoming even more important. Thus, to achieve the desired quality, it is necessary to carry out the entire dispensing process in an evacuated environment, i.e. in a vacuum, and precisely position the workpiece while it is processed. At the same time, components are becoming ever more complex. Their shape and textures are not, of course, optimised for ease of bonding or sealing, because other criteria are more significant. As a result, the dispensing material may form gaps around edges or in corners of the workpiece. Coiled products, such as transformers, motors or ignition coils inherently contain very small gaps, which must be filled without bubbles. Another consideration are the growing requirements for electronic components. They ultimately lead to increasing demands on dispensing, too. Superior dispensing quality to maximise highvoltage and insulation resistivity, for example, is therefore a must, and that requires an uninterrupted, stable vacuum. A production process completely free of air bubbles and with effective protection against moisture is today’s state of the art, and process reliability here is equal to that of atmospheric-pressure dispensing.

Ultimate Economic Efficiency and Quality to Suit the specific requirements Vacuum Dispensing The vacuum dispensing systems from Scheugenpflug are equipped with a metering unit for 1C or 2C media and have been developed for economic volume production at ultimate quality levels. Process reliability in this case matters most, which is ensured through reliable dispensing and repeatability. To ensure bubble-free feeding of the dispensing medium one of the A310 preparation and feeding units see page 40 is used. Powerful vacuum pumps evacuate the entire space around the component or components....

LeanVDS B and LeanVDS U Models compact Entry-Level Model As vacuum dispensing is gaining in importance, the demand for systems for lower production volumes and entry-level models that use this technology is also growing. With its LeanVDS models, Scheugenpflug now offers vacuum dispensing systems that put quality vacuum dispensing within reach of that market sector’s budgets, making unreliable re-evacuation as a result of cutting corners when investing in a vacuum system a thing of the past. The LeanVDS is available in sizes 300 × 300 mm without axes (Basic) and from sizes 420 × 420 mm with...

Optimized for Large Workpieces Even if many components are becoming ever smaller, large and very large parts must also sometimes be filled under vacuum. In these cases, the vacuum dispensing system Basic is the right choice. As these large components do not have to be – and often cannot be – moved within the unit, the system does not need motion axes, making it less complex and more easily scalable. The control unit for the VDS B is the UVISneo see page 82. A quick overview: Multi-nozzle (+) Cycle time (+) Workpiece size ++ ++ = very good + = good (+) = limited – = not recom. VDS B...

Allrounder for a broad Range of Requirements In electronics manufacture, flexibility is the domain of universal systems, which allow a quick reaction to product changes. The vacuum dispensing system Universal is ideally suited for flexible volume production of medium-sized and large workpieces. Whether you are facing demanding component geometries, complex dispensing programs or a wide range of different workpieces, with this system you are prepared for everything. The VDS U is usually equipped with three motion axes and an automatic cup position. The VDS U uses the UVISneo control unit see...

Power to make Time less of a Limitation Time can be a limiting factor for many reasons. This problem can be easily overcome with the vacuum dispensing system VDS P(ower), which is usually equipped with three motion axes, an automatic cup position and a multi-piston metering system (2- to 8-nozzles, depending on required performance; other sizes on request). In a single evacuation cycle, as many components as possible are processed at the same time. They are arranged in an even grid, so that one dispensing stroke processes several workpieces at once. This system is the perfect solution for...
