First paper – TBA
Second paper – Topics and trends in ESD control in 2016
The field of ESD control might seem to the casual observer to be – well, “static”! Not so – Jeremy takes a brief look at the 61340-5-1 ESD control standard for electronics manufacture and the thinking behind changes that will come in with a new 2016 version. He takes a look at the activities of the Industry Council on ESD Target Levels and trend in increasing susceptibility of ESD sensitive electronic devices. There has been confusion in the industry over the relationship between component ESD susceptibility and system susceptibility to ESD during operation, leading to the Ind. Co. White Paper 3 and concept of System Efficient ESD Design (SEED).
Finally, Jeremy describes a new project on control of electrostatic threats in healthcare facilities, recently started in IEC TC101.
Third paper – Calibration of PFD probes in non-sinusoidal fields
Electromagnetic field probes are often used to demonstrate compliance with ICNIRP guidelines. A probe is calibrated against a continuous wave field, but is subsequently used to measure a variety of modulated and pulsed signals. Probes have previously been observed to under- or overestimate electromagnetic exposure in these harsher environments. This work focuses on the measurement of low frequency (< 100 kHz) fields that are commonly encountered in industrial, scientific and medical environments such as around welding machines and in the vicinity of MRI scanners. The periodic but non-sinusoidal structure of these waveforms present a unique set of challenges when quantifying the probe performance. The performance of a test probe is tested against a series of trapezoidal and more realistic waveforms, and it is concluded that the bandwidth alone may not be sufficient to determine whether a probe is suited to a particular set of measurements.
Fourth paper – Trials and tribulations of the Radio Equipment Directive – changing requirements for broadcast receivers and related matters
On 13 June 2016 broadcast receiver move into the radio Equipment Directive. This means that Article 3.2 will apply for the first time “Radio equipment shall be so constructed that it both effectively uses and supports the efficient use of radio spectrum in order to avoid harmful interference”. Brian will describe what has been happening on the standards front for TV receivers (and what has not, for radio receivers).
Information on speakers
Speaker 1 – TBA
Speaker 2 – Dr Jeremy Smallwood BSc CEng MIET CPhys FInstP
Jeremy spent seven years as an electronics designer before returning to Southampton University to complete his PhD researching electrostatic discharge (ESD) ignition of pyrotechnic materials. He later worked at ERA Technology Ltd. on electrostatics R&D projects and consultancy. In 1998 he started Electrostatic Solutions Ltd, specialising in training, consultancy, test and R&D for the electronics industry, electrostatic hazards avoidance, electrostatic materials measurement and applications development.
Jeremy has over 50 publications in electrostatics, ESD ignition hazards and ESD control in the electronics industry. In 2010 he was awarded the ESD Association Industry Pioneer Recognition
Award. He is a regular speaker at international conferences and workshops. He is active in British Standards panels on handling of electrostatic sensitive devices and control of undesirable static
electricity. Between 2000 and 2012 he was Chairman of International Electrotechnical Commission Technical Committee 101 (Electrostatics) responsible for world standards in electrostatics, and
continues to work as a UK expert delegate to this Committee. From 2013 – 2015 he held a part time post as Snr. Research Fellow at Southampton University High Voltage Group while maintaining his Electrostatic Solutions Ltd consulting, research and training activities.
Speaker 3 – Ralf Mouthaan
Ralf Mouthaan studied physics at the University of Nottingham and graduated in 2008. He has since worked at the UK’s National Physical Laboratory as part of the Electromagnetic Technologies group.
Ralf’s work has focused on electromagnetic exposure metrology, developing and maintaining the UK’s national standards in this area. He has contributed to calibration services for electromagnetic field probes, specific absorption rate probes, induced current clamps and MRI implant safety. Other interests have included dielectric measurements, pulse risetime measurements and implanted antennas.
