Electronics Interconnection (EI) webinar series

 


 




NPL's Electronics Interconnection (EI) Group is presenting a new series of technical webinars in 2018.

This Group is internationally recognised for its practical and innovative work on lead-free reliability, PCB interconnection failures, tin whisker migration and conformal coating research.

These FREE online webinars provide the opportunity to draw on years of practical experience without the participant needing to leave his/her desk – to participate, all that is needed is a phone line and Internet access. Please note that registration is essential.

The majority of webinars run for between 60–90 minutes (and is limited to 100 delegate/company registrations). After the webinar, participants receive a copy of all of the slides and a listing of all relevant technical reports which can be downloaded for FREE.

Please note that all webinars are at UK time - check local time in other countries here

A Beginner's Guide to SIR, CAF and Condensation Testing
Presented by Martin Wickham

Tuesday 17 July 2018 (14:30 hrs UK time)

Book your place here

This webinar will discuss the advantages of using Surface Insulation Resistance testing to evaluate assembly processes and materials. It discusses test vehicle design, how to go about the testing and how to analyse the results. Conductive Anodic Filament testing will also be covered, including test vehicle design, test procedures and parameters, and failure analysis. The final part of the webinar will cover Condensation Testing and how it can be used to assess conformal coatings.

The webinar will cover:

  • Surface insulation resistance testing of printed circuit boards
  • Conductive anodic filament testing of printed circuit boards
  • Condensation testing to assess conformal coated assemblies

The majority of webinars run for between 60–90 minutes, with a Q&A session. The webinars are limited to 100 delegates/companies. A copy of each of the slides presented and links to NPL reports will be provided after the webinar.



Characterisation and Testing of Hydrophobic and Water Resistant Coatings – The Next Generation in Coating Technology?
Presented by Laura Kent

18 September 2018 (14:30 hrs UK time)

Book your place here

The application of electronics into new and increasingly harsh environments has paved the way for the development of a new generation of hydrophobic and water resistant coatings. Whilst traditional conformal coatings have been highly successful, they still absorb some moisture due to their polymeric nature. Issues have also arisen in terms of the coverage of fine details. The application of a hydrophobic coating, on its own or in addition to the conformal coatings may prove a potential solution to overcome these issues. This webinar looks at the application of these hydrophobic coatings both to a bare board and deposited on top of a conformal coating.

The webinar will cover:

  • Hydrophobic and water resistant coatings
  • Surface insulation resistance (SIR) humidity tests
  • Condensation testing
  • Water contact angle and surface energy tests
  • Future development work

The majority of webinars run for between 60–90 minutes, with a Q&A session. The webinars are limited to 100 delegates/companies. A copy of each of the slides presented and links to NPL reports will be provided after the webinar.



Condensation Testing – Initial Results from a Round Robin Project
Presented by Ling Zou

20 November 2018 (14:30 hrs UK time)

Book your place here

NPL has been working with 11 industrial partners to develop a test methodology for condensation testing to enable relative performance of conformal coatings to be determined. Details will be given of the test vehicle which has been designed incorporating components to provide a tougher coating challenge. A short-term test methodology has been devised using three increasing levels of condensation over a 24-hour period. Initial test results using the methodology with a range of common coatings will be given, including a discussion of how the results are analysed. Recent work on developing a method for condensation testing of double sided assemblies will also be given.

The webinar will cover:

  • Condensation testing of coated assemblies
  • Test methodology development for condensation testing
  • Double sided assembly condensation testing

The majority of webinars run for between 60–90 minutes, with a Q&A session. The webinars are limited to 100 delegates/companies. A copy of each of the slides presented and links to NPL reports will be provided after the webinar.
