The National Physical Laboratory (NPL) is internationally recognised for its practical and innovative work on electronic interconnection reliability, printed circuit board (PCB) failures and conformal coating research. We offer a range of webinars at no charge, giving you the opportunity to draw on years of practical experience without leaving your desk.
Electrical fatigue degradation in coatings due to partial discharge
Degradation of dielectric materials can occur when they are subjected to multiple partial discharges. These may lead to a reduction in their electrical withstanding voltage and result in full dielectric breakdown at significantly lower voltages. NPL has developed capability to test multiple samples simultaneously at low pressure, where partial discharges and subsequent full breakdown can occur at lower voltages. This webinar will give details of the new system and show examples of coating tests, giving the outcomes of applying multiple partial discharges to PCB protective coatings.
Presenters - Ana Robador, Meenakshy Ramankutty and Martin Wickham
Tuesday 9 September 14:30 – 15:30
Did you miss our last electronics reliability webinar? Make sure to catch up on YouTube to find out more about high voltage partial discharge measurements in multilayer printed circuit boards. You can access our full list of past webinars on our YouTube channel. If you’d like to be kept up to date about the next webinar in our electronics reliability series, please complete the ‘contact us’ form below and ‘opt-in’ to receive emails.
You are welcome to attend both webinar formats. A copy of the slides presented, access to the webinar recording and links to NPL reports will be provided after each webinar where appropriate.
Our series of fundamental webinars are aimed at early career engineers, reviewing measurement techniques and how to apply them to better understand reliability performance and potential impact on product life cycle. These quick-fire sessions allow a high level of knowledge exchange where technical knowhow is not essential and are an excellent precursor to product trouble shooting and quality control.
The majority of our technical webinars run for 60 minutes and provide in depth analysis and measurement of testing and performance of applications where we review techniques and better understand reliability performance. These sessions provide interpretation and are crucial in the support of product development and in-field performance issues.
