Bob has been involved with the introduction and implementation of lead-free process technology for the last seven years. He recently received A SOLDERTEC/Tin Technology Global Lead-Free Award for his contribution to the industry to help the implementation of the technology. He was responsible for co-ordination and introduction of the first series of hands-on lead-free training workshops in Europe for Cookson Electronics during 1999-2001. These events were run in France, Italy and the UK and involved lead-free theory, hands-on paste printing, reflow, wave and hand soldering exercises. Each non commercial event provided the first opportunity for engineers to get first hand experience in the use of lead-free production processes and money raised from the events was presented to local charity. More recently he co-ordinated the SMART Group Lead-Free Hands On Experience at Nepcon Electronics 2003. This gave the opportunity for over 150 engineers to process four different PCB solder finishes, with two different lead-free pastes through convection and vapour phase reflow. He also ran the Experience 2 & 3 in 2004/2005. 2006 sees Nepcon back at Birmingham and Bob will again be organising the features. Bob was recently presented with awards from the SMTA and IPC for his industry support.

He has also run training workshops with research groups like ITTF, SINTEF, NPL & IVF in Europe. Bob has organised and run three lead-free production lines at international exhibitions Productronica, Hanover Fair and Nepcon Electronics in Germany and England to provide an insight to the practical use of lead-free soldering on BGA Ball Grid Array, CSP Chip Scale Package, 0210 chip and through hole intrusive reflow connectors. This has resulted in technical papers being published in Germany, USA and the United Kingdom.

Dendrite Failure – Causes & Cures Webinar

Mar 24, 2018 | Dendrite failure on printed circuit board assemblies is quite common but often not investigated fully to pin point the root cause. This is due to the intermittent nature of the failure or just replacing components seems to solve the problem Book at https://www.bobwillis.co.uk/event/dendrite-failure-causes-cures/

Manual Cleaning of Printed Board Assemblies – Step By Step Guide Coming Soon

Oct 23, 2017 | After rework, modification or second stage assembly cleaning may need to be considered. Ideally a no clean flux, gel or solder paste should be used to avoid the need to clean selected areas. If manual cleaning is to be conducted every effort should be made to use materials or application methods that result in the minimum residues from the soldering process Planning and training staff in manual cleaning is very important to get the best possible result visually and to maintain product reliability. This is one of the first training sessions to cover manual cleaning of board assemblies, highlighting the problems and solutions to manual cleaning To ensure you are equipped to get maximum benefit from the event, read our Webinar Guide https://www.bobwillis.co.uk/wp-content/uploads/2017/01/WebinarAttendance2017.pdf
