- Reduce the temperatures and process times of electroless and immersion plating processes using ultrasound.
- Study the effect of pulsed ultrasound on electroless and immersion plating.
- Evaluate alternatives to formaldehyde and/or use ultrasound to reduce the concentrations of formaldehyde employed in electroless copper.
- Investigate the effect of ultrasound on the grain structure, porosity, coverage, throwing power and composition of the electroless and immersion deposits
- Determine feasibility of scale-up with pilot-scale production tests.
- Dissemination of results and findings through publication of quality papers in journals and presentations at prestigious international conferences
Environmental benefits – this project has shown how ultrasound can be used to lower electroless plating temperatures saving energy and water usage. In addition the reduction in formaldehyde concentrations has benefits in terms of health and safety.
Economic benefits – reduced energy and water consumption leads to lower manufacturing costs. Increasing the plating speed by up to 35% represents potential for increased production capacity.
Societal benefits – The electronics sector is competing against the low cost economies of the World. The potential cost reductions that have been demonstrated will help protect jobs in the UK
The results from this project have led to 2 follow on projects namely:
KTP with The National Physical Laboratory (NPL) –using Coventry’s knowledge of electroless and immersion deposition for selective metallisation of fabrics.
KTP with Stevenage Circuits Ltd - the use of ultrasound to enable enhanced coverage and planarization in electrochemical deposition processes.
A number of other funding proposals based on this project are planned to be submitted to H2020 calls whilst an EPSRC platform bid on Electroless Plating of Injection Moulded Waveguides has been submitted.
Dissemination – presentations have been given at 22 conferences and seminars including major international conferences such as;
• May 2014, 13th Electronic Circuits World Convention, Nuremburg, Germany
• October 2013, IMAPS 2013, Orlando, USA (Invited)
• November 2012, XIII World Interfinish Congress and Exhibition, Milan, Italy
• September 2011, Eurocorr 2011, Stockholm, Sweden
Journal publications – 1 journal paper and 2 conference papers have been published whilst 4 more are either in preparation or at peer review.
Preventing Motion Sickness in Automated Vehicles
The overall aim of this JIP accordingly is to avoid or minimise the occurrence of motion sickness in automated vehicles. The project aims at realising this by explicating the underlying causes of motion sickness in automated vehicles, adopt reliable, sensitive, and valid methods to assess its occurrence, and sketch ways it can be mitigated by adapted (automated) vehicle design and/or other countermeasures.
SUITS (Sustainable Urban Integrated Transport Systems: Transferable tools for S-M local authorities) aim is to substantially increase the capacity of Small-Medium local authorities to develop and implement sustainable, inclusive, integrated and accessible transport strategies, policies, technologies, practices, procedures, tools, measures and intelligent transport systems that recognize the end-to-end travel experiences of all users and freight.
Physics and Ballet
Researchers from Coventry University's Mobility & Transport joined members of the Royal Ballet got together in February to explore the dynamic relationship between physics and ballet.
Optimisable system-level thermal models for power electronic converters
This project is focused on the design of reliable yet efficient thermal models underpinning an optimal design framework for power electronic converters. Due to the high number of times these models must be evaluated during the optimisation process, they are required to be of low computational cost (so-called ‘optimisable’).
