Micro Assembly using Surface Tension

New course organized by FSRM. The objectives of the course is to present the applications of surface tension in Microsystems (microgrippers, fluidic lenses, actuators, valves, sealing systems…), to give the fundamentals in order to be able to understand capillary forces models from literature, to provide basics for capillary forces measurements and for surface tension based design. A strong focus will be put on micro-assembly applications (gripping, self-centering).

Target group
PhD students, researchers and engineers involved in surface microfluidics, micromanipulation or precision assembly. Designers active in the field of microsystems and brought face to face with adhesion and stiction in MEMS.

Content

  • key concepts towards capillary forces modelling and its possible application to the fields of microrobotics and microassembly: surface energy, surface tension, the contact angles and wettability together with the Young-Dupré equation, the pressure drop across the interface described by the so-called Laplace equation, the curvature of a surface in the 3D space. Additional concepts are the contact angles hysteresis, the surface impurities and heterogeneities, the dynamic spreading of a liquid on a substrate.
  • capillary forces modeling: models at equilibrium (2D and 3D), capillary forces at the sub-millimetric and nanometric scales
  • self-assembly: applications, main parameters and models for self-centering effects and oscillations damping
  • state-of-the-art, based on the fact that surface tension forces linearly decreases with the size while the weight decreases more quickly. While surface tension has been pointed out as being one of the disturbing effects in MEMS (stiction problems [kondo05, mastrangelo93, wu06]), other uses have been positively considered [berge93, hendriks05, lee00, oh06]. More particularly, surface tension effects have been applied to many fields such as capillary gripping [bark99, grutzeck99, obata04, biganzoli05, lambert06, schmid06], fluidic microvalves [feng03], actuation [borno06], optics [berge00].

Tutors
Pierre LAMBERT is CNRS senior researcher at FEMTO-ST (he was previously Assistant Professor at Université libre de Bruxelles). He has been active in the field of micro-assembly and surface forces modeling for many years. After obtaining his PhD in 2004, he developed microgripping applications at EPFL (LPM) in 2005 and in the Université Pierre and Marie Curie (2006). In 2008 he was visiting Professor at the EPFL (LPM) in the field of forces measurement and in 2009 he has been a scientific collaborator of the European project HYDROMEL.
In the field of the course, he is the author “Capillary Forces in Microassembly”, edited by Springer NY in 2007 and is the co-author of “Robotic Microassembly”, to be edited soon by Wiley-Interscience.

German machine tool industry anticipates significant recovery in demand for 2010

Germany’s machine tool industry is gaining renewed confidence for 2010. “Though the ongoing year is once again going to be a very difficult one, we nonetheless expect a significant upturn in business during the first half of the year”, explains Martin Kapp, Chairman of the VDW (German Machine Tool Builders’ Association), at the organisation’s annual press conference.

“Since September, orders have improved month by month”, he says in support of his assessment. In the fourth quarter of 2009, order bookings were up by 12 per cent from a low level. This is not due solely to the base effect: on the contrary, the order level has risen by more than 60 per cent compared to its nadir in July/August.

METAV 2010 showcases intelligent production technology for new requirements
The international machine tool industry is gearing up for the METAV in Düsseldorf from 23 to 27 February 2010. 680 prestigious exhibitors from 26 different counties will there be showcasing their innovations in terms of products and services for new requirements in industrial manufacturing operations. When it comes to new products, new markets, new processes, new concepts for corporate structures and cost optimisation, the German manufactures, in particular, have a lot to offer. When the Gordian knot has been cut and the global industrial sector is investing again, Germany’s machine tool industry will be up there with the front-runners, emphasises VDW Chairman Martin Kapp.
 
Very good mood @ the show
In fact I am in Düsseldorf these days and I can confirm the general trend. The alleyways are quite full and people are positive. Obviously it’s only part of the reality, but that part is really nice.

Planned productivity gains

In today’s difficult business environment, manufacturers are looking to boost their productivity and competitiveness – sustainably and substantially. ISCAR has launched a new 3P Productivity Plan, which already has helped hundreds of successful manufacturers to see an immediate savings of more than 25% in production cost due to an improvement in metalcutting productivity, plus better  ROI, speed of delivery and all-around competitiveness.

Important changes
The best part is that they see the gains sooner than they would by going it alone. Perhaps most important, they also acquire an organizational culture that welcomes change and continuous improvement. And who can put a price on that?
Among the 3P Productivity partners are the biggest names in automotive, off-road equipment, aerospace and medical device manufacturing, as well as world-class contract manufacturers and die and mold shops. A multitude of countries around the globe are represented. And the roster grows monthly. One thing they share in common is the drive for sustainable improvement in overall profitability and competitiveness, not just a one-shot fix for a single operation.
“Under the 3P Productivity Plan we follow a proven protocol leading to better productivity/profitability solutions sooner — and the advice is free,” says Jacob Harpaz, ISCAR CEO and IMC Group President. “We literally partner with the customer to improve their entire manufacturing environment, physically and organizationally.”

Immediate savings
Experience has shown that the early retoolings generate enough savings to fund the more capital-intensive changes later on. “Their pay-as-you go approach made implementation much more affordable,” said one 3P partner, a European medical device manufacturer. Recently, these early retoolings have produced even larger savings, thanks to new ISCAR high-performance SUMO TEC tools. Featuring a proprietary coating treatment, these inserts outproduce and outlast conventional inserts by wide margins.  ISCAR now offers most popular milling insert styles in SUMO TEC versions, and is expanding the SUMO TEC line to include tangential milling, holemaking, turning and parting tools as well.

We will go more in detail in the 3P programme in Eurotec’s next issue.

Take a very close look at Microsys

In addition to already well established trades fair including Motek, Control and Blechexpo, private trade fair promoter Paul Schall is now bringing a further event to the trade fair venue in Stuttgart. The 4th Microsys trade fair for micro and nano-technology will take place concurrent to the Motek international trade fair for assembly and handling technology at the Stuttgart Exhibition Centre from September 13 to 16, 2010.


Micro-technology makes ordinary things smaller, handier and more multifunctional. As a result, electronic controllers in cars now fit onto tiny chips and sensors. Driving is made more comfortable and safer. Driver assistance systems are experiencing a strong upsurge: The intelligent car compensates for things the driver doesn’t notice – it reacts more quickly at the decisive moment, “sees” better than the human eye at night and in the fog, and even scans the road. Combination radio / CD players, which were as large as a chest of drawers 10 years ago, are shrinking down to extremely small, compact systems thanks to micro-technology.

Nano-technology products can also be found in our daily surroundings, and offer practical advantages: glasses which no longer become fogged, sinks which require less frequent cleaning, cars which are washed clean by the rain, and textiles to which spots no longer adhere. All of this is made possible by extremely small particles in nano-coatings. Our television pictures become sharper and flat screens are flat because their control processes operate in miniature format.

A very targeted show
International exhibitors will demonstrate how micro and nano-technology products are manufactured and used at Microsys. “We currently see excellent opportunities for the development of micro and nano-technology for use in a broad range of industrial applications”, says trade fair promoter Paul Schall in his announcement. Whereas some of the competitors are concentrating to a greater extent on research, electronics or medical engineering, Schall is emphasizing the field of applied production technology as a thematic orientation for the event.

Small and efficient
Micro-technology deals with processes which are used for the production of bodies and geometric structures with dimensions in the micron range. To put this into perspective, a human hair has a diameter of 70 microns. The largest field of application for micro-technology is the production of integrated circuits, which were essential in making modern computer technology possible at all. In the case of structural dimensions of less than 100 nanometres we speak of nano-technology. One nanometre is roughly 70,000 times smaller than the diameter of a human hair.
