Wet Processing Technologies for Large Area Electronics

 

The Wet Processing Short Course is delivered by Printed Electronics Ltd (PEL) and the Centre for Process Innovation (CPI). It covers the inks and printer technology required for deposition techniques including screen, inkjet and flexo/gravure printing. The short course also covers coating techniques such as doctor blade and slot die, drawdown, spin and spray coating. In each case the advantages, disadvantages and technological challenges of each technique will be covered, along with issues arising in scale up for manufacture

Nicola Broughton, Senior Scientist
CPI, UK

Nicola is a Senior Scientist working on collaborative and commercial research projects in the field of printable electronics. With a background in cell biology, Nicola has worked as an industrial laboratory chemist developing new products and formulations for an aerosol manufacturer. At CPI Nicola has worked to develop functional ink formulations, particularly those containing nanomaterials. She also works to establish coating, printing and curing methods for a number of different applications including IoT enabled devices, wearable electronics and sensors.

 

Dr Rob Valentine
CPI, UK

Dr Rob Valentine graduated from University of Durham with an MChem before undertaking a PhD at the University of Edinburgh in the Synthesis and Characterisation of Novel Organic Electronic Materials. Following these postgraduate studies Rob joined CPI in 2012 where he has been ever since. During his time at CPI Rob has developed particular expertise in a range of topics including OTFT, Photovoltaics and Sensor Technologies covering areas such as material formulations, deposition techniques and device architecture.

 

Dr Neil Chilton, Technical Director
Printed Electronics Limited, UK

Neil has more than twenty years’ experience in the field of electronics and electronic components. After completing his BSc and PhD in Physics, his technical career took him to Japan where he worked for four years at the advanced materials research division of Nippon Steel Corporation. After returning to the UK he joined Europe’s then largest printed circuit board manufacturing company where he was later part of an MBO team and technical director. In 2006, together with co-founder Dr Steve Jones, he started Printed Electronics Limited to focus on the practical use of inkjet for manufacturing electronic interconnects, devices and systems
