Evaluation of embedded electronics for use in harsh environments
Presented by Dan Flintoft Tuesday 1 October 2019 (14:30 hrs UK time) Book your place here
The ongoing trend of miniaturisation in the electronics industry has been focused on the reduction in size of components and component packaging. However, with an inevitable limit due to manufacturing capability, an alternative is required. Device embedded substrates are a promising solution which looks at miniaturisation from a substrate perspective, using a 3D approach to circuit design by placing components into the substrate as well as on the surface. This manufacturing method has been shown to increase circuit density, reduce signal paths, and reduce parasitic capacitances and inductances. Devices containing embedded components are already on the market but have yet to be evaluated fully for use in harsh environments.
NPL's work in this area, in collaboration with the University of Surrey, is looking at the reliability of embedded electronics to evaluate them for use within harsh environments through the creation of a test vehicle which was designed for testing of the reliability of the interconnect structures connecting the components. This is being achieved through the use of NPL's harsh environment test facilities. The ongoing testing, for example thermal cycling from –55 ºC to +125 ºC, will indicate the structure's suitability for use in harsh environments. Testing will also provide an insight into adaptations required in the standard testing parameters for industry.
Battery metrology at NPL – lithium ion cell characterisation
Presented by Kate Clayton Tuesday 12 November 2019 (14:30 hrs UK time) Book your place here
In 2017, the government announced the end to sales of new conventional petrol and diesel cars and vans by 2040 in order to reduce carbon emissions and the associated negative health effects from poor air quality. Electric vehicles (EVs) are expected to provide an alternative solution to the ban. However, increasing sales in EVs requires an improvement in consumer confidence. The government has announced to make over £600 million of funding available to support the uptake and manufacture of ultra low emission vehicles with an investment of £246 million to support the development of new battery technologies.
Research in battery technology is a growing area with lithium ion chemistry set to dominate the electric vehicle market in the short to medium term due to its high energy density and low self-discharge properties. However, the need for improvement is great with focus directed towards lowering cost, improving performance and increasing the safety of the battery. Success in these areas is expected to open a competitive market, improve consumer confidence and increase the uptake of EVs on the road. Battery metrology is a strategic focus for NPL and pivotal for the realisation of zero emission vehicles.
Register for this talk to hear about the facilities at NPL available for lithium ion battery metrology, our capability in this area with a focus on using electrochemical impedance spectroscopy to evaluate the battery system and the research that we have been doing upon nickel manganese cobalt (8:1:1) and graphite electrode materials.
