National Physical Laboratory proudly showed, for the first time publicly, a time-lapse film taken over a 24-hour period, showing the complete disintegration of pure tin.

This Tin Pest video is a world first and is likely to be requested by other technical organisations. NPL is currently looking to see how best to provide access for its showing.

This Soldering Science & Technology Club meeting was well attended to hear the presentations by the NPL team:

‘Improving the Prediction of Reliability Performance of Lead-Free Assemblies’ – Milos Dusek

‘Reliability in High Frequency Vibration of Lead-Free Solder Joints’ – Davide Di Maio

‘A New Technique for Reliability Assessment based on Power Cycling’ – Milos Dusek

‘Corrosion Properties of Lead-Free Alloys’ – Ling Zou

‘Will Tin Finished Components Whisker?’ – Martin Wickham

‘Measuring the Tin-pest Transformation’ Davide Di Maio

‘Reliability of Substrates after Processing at Lead-Free Soldering Temperatures’ – Martin Wickham

Dr. Chris Hunt, Chairman for the day, also introduced Paul Cooper from Radstone Digital Processing who presented ‘ Thermal Management Technology Developments in the US’, a report on a UK DTI Mission to assess the use of modelling with both passive and active cooling scenarios, assess market uptake and identify potential collaboration partners.

The final joint presentation of the day was by Bob Willis & Chris Hunt outlining plans for the ‘NPL Industry Defect Database’.

All presentations are available on the NPL website: www.npl.co.uk/ei/
