Unit 3 Compliance is a West Yorkshire test lab and consultancy specialising in EMC testing, troubleshooting/problem solving, pre-compliance and product design support.
James has 10+ years’ experience in EMC design, testing, fault finding and problem diagnosis and in running an EMC test laboratory. He finds his wide ranging electronics and product design background invaluable in coming up with innovative solutions to all manner of EMC problems.
His career has spanned several different disciplines including industrial LCD monitor design, SMPS design, microcontroller coding, environmental testing, thermal design and simulation, high speed digital design/test and project management.
Outside of work James is a keen board gamer, cyclist, runner and mountaineer and can often be found on the local hills, occasionally muddy.
Radiated emissions made easy
This lecture will give you the basis on how to design digital products that meet EMC standards.
The importance of designing a PCB stack will be explained. The main topology of the PCB stackup, e.g. 4 layers, 6 layers, 8 layers, and 10 layers topology.
Typical issues with a missing ground plane during radiation emissions, conductivity immunity, and radiation immunity tests.
Typical emissions with poor stack up in the range 200 MHz - 1 GHz.(and why they look like that)
Then we will give some suggestions for routing signals between different layers to avoid EMC and SI problems.
We will discuss why the selection and type of capacitors and placement are so important in a digital circuit design. We will also discuss their effect on the bandwidth 1 MHz - 80 MHz.
Having spent more than 25 years working in the electronic field, Francesco is widely recognized as an industry expert. The services that he provides include electronic design, firmware development and PCB layout engineering. Additionally, he is an expert in EMI/EMC and helps companies that are having trouble passing EMC. As a result of his approach, he has been able to provide a working solution for many companies that previously failed EMC.

Practical EMC design considerations
In order to achieve electromagnetic compliance, it is key to consider various parasitic elements and their impact on noise as well as insertion loss. Practical design considerations based on a Flyback converter demo will be presented, identifying alternative component solutions and filtering in order to improve signal integrity and EMC.
Mohamed comes from a power supply design and development background. He worked in the Aerospace Industry for 10 years designing power supplies on various civilian and military projects. In addition, he was responsible for EMC testing, filter design and compliance. In the past 6 years before joining Wurth Electronics, he taught a variety of subjects at University towards a BTEC degree in electronics engineering. He joined Wurth in April 2015 as a Field Applications Engineer responsible for the South of the England, Wales and Ireland.
